ITEM 1.  BUSINESS.
- -------  ---------

(a)  GENERAL DEVELOPMENT OF BUSINESS.

      Harleysville Group Inc. (the "Company") is a regional
insurance holding company headquartered in Pennsylvania which
engages, through its subsidiaries, in the property and casualty
insurance business.  As used herein, "Harleysville Group" refers to
Harleysville Group Inc. and its subsidiaries.  Harleysville Group
is approximately 54% owned by Harleysville Mutual Insurance Company
(the "Mutual Company").

      Harleysville Group and the Mutual Company operate together as
a network of regional insurance companies that underwrite a broad
line of personal and commercial coverages.  These insurance
coverages are marketed primarily in the eastern and midwestern
United States through approximately 22,600 independent insurance
agents associated with approximately 3,000 insurance agencies. 
Regional offices are maintained in Georgia, Illinois, Indiana,
Maryland, Massachusetts, Michigan, Minnesota, New Jersey, New York,
North Carolina, Ohio, Pennsylvania, Tennessee, Virginia and
Wisconsin.  The Company's property and casualty insurance
subsidiaries are:  Great Oaks Insurance Company ("Great Oaks"),
Harleysville-Atlantic Insurance Company ("Atlantic"),  Harleysville
Insurance Company of New Jersey ("HNJ"), Huron Insurance Company
("Huron"), Lake States Insurance Company ("Lake States"), Mid-
America Insurance Company ("Mid-America"), Minnesota Fire and
Casualty Company ("Minnesota Fire"), New York Casualty Insurance
Company ("New York Casualty") and Worcester Insurance Company
("Worcester").  

      The Company is pursuing a strategy of building a national
network of regional insurance companies.  Management believes that
the Company's regional organization permits each regional operation
to benefit from economies of scale provided by centralized support
while encouraging local marketing autonomy and managerial
entrepreneurship.  Services which directly involve the insured or
the agent (i.e., underwriting, claims and marketing) generally are
performed locally in accordance with Company-wide standards to
promote high quality service, while actuarial, investment, legal,
data processing and similar services are performed centrally.  The
Company's network of regional insurance companies has expanded
significantly in the last fourteen years.  In 1983, the Company
acquired Worcester, a property and casualty insurer which has
conducted business in New England since 1823.  In 1984, HNJ was
formed by the Company and began underwriting property and casualty
insurance in New Jersey.  In 1987, the Company acquired Atlantic,
a property and casualty insurer which has conducted business in the
southeastern United States since 1905.  In 1991, the Company
acquired Mid-America, (formerly named Connecticut Union Insurance
Company) which conducted business in Connecticut, and New York
Casualty, which conducts business in upstate New York.  In 1993, 

                                          3

the Company acquired Lake States, which primarily conducts business
in Michigan.  In 1994, the Company formed Great Oaks which began
underwriting property and casualty insurance in Ohio.  In 1997, the
Company acquired Minnesota Fire, which primarily conducts business
in Minnesota and neighboring states.

      The Company's property and casualty subsidiaries participate
in an intercompany pooling arrangement whereby these subsidiaries
cede to the Mutual Company all of their net premiums written and
assume from the Mutual Company a portion of the pooled business,
which included all of the Mutual Company's property and casualty
insurance business except for new and renewal Pennsylvania personal
automobile insurance insured after January 1, 1991 by a subsidiary
of the Mutual Company, Pennland Insurance Company ("Pennland") and
new and renewal New Jersey personal automobile insurance insured
after January 1, 1992 by another subsidiary of the Mutual Company,
Harleysville-Garden State Insurance Company ("Garden State"). 
Beginning January 1, 1996, Harleysville Group's participation in
the pooling arrangement increased from 60% to 65% and Pennland
became a participant in the pooling arrangement.  Beginning January
1, 1997, Harleysville Group's participation in the pooling
arrangement increased from 65% to 70% and Lake States became a
participant in the pooling arrangement.  Beginning January 1, 1998,
Harleysville Group's participation in the pooling arrangement
increased from 70% to 72% and Minnesota Fire became a participant
in the pooling arrangement.  See "Business - Narrative Description
of Business - Pooling Arrangement."

      The Company is a Delaware corporation formed in 1979 as a
wholly-owned subsidiary of the Mutual Company.  In May 1986, the
Company completed an initial public offering of its common stock,
reducing the percentage of outstanding shares owned by the Mutual
Company to approximately 70%.  In April 1992, the Mutual Company
completed a secondary public offering further reducing the
percentage of outstanding shares owned by the Mutual Company to
approximately 54%. 

(b)  FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS.

      The Company is of the opinion that all of its operations are
within one industry segment and that no information as to industry
segments is required pursuant to Statement of Financial Accounting
Standards No. 14 or Regulation S-K. 

                                          4

(c)  NARRATIVE DESCRIPTION OF BUSINESS.

PROPERTY AND CASUALTY UNDERWRITING

      Harleysville Group and the Mutual Company together underwrite
a broad line of personal and commercial property and casualty
coverages, including automobile, homeowners, commercial multi-peril
and workers compensation.  The Mutual Company and the Company's
insurance subsidiaries participate in an intercompany pooling
arrangement under which such subsidiaries and the Mutual Company
combine their property and casualty business.  Garden State has not
participated in the pooling arrangement.  On January 1, 1996,
Pennland began participation in the pooling arrangement and
Harleysville Group's participation increased to 65%.  Beginning
January 1, 1997, Harleysville Group's participation in the pooling
arrangement increased from 65% to 70% and Lake States became a
participant in the pooling arrangement.   Beginning January 1,
1998, Harleysville Group's participation in the pooling arrangement
increased from 70% to 72% and Minnesota Fire became a participant
in the pooling arrangement.

      Harleysville Group and the Mutual Company have a pooled rating
of "A" (excellent) by A.M. Best Company, Inc. ("Best's") based upon
1996 statutory results and operating performance.  Best's ratings
are based upon factors relevant to policyholders and are not
directed toward the protection of investors.  Management believes
that the Best's rating is an important factor in marketing
Harleysville Group's products to its agents and customers.

      The following table sets forth the premiums earned, by line of
insurance, for Harleysville Group for the periods indicated:

      The following table sets forth ratios for the Company's
property and casualty subsidiaries, prepared in accordance with
generally accepted accounting principles ("GAAP") and with
statutory accounting practices ("SAP") prescribed or permitted by
state insurance authorities.  The statutory combined ratio is a
standard measure of underwriting profitability.  This ratio is the
sum of (i) the ratio of incurred losses and loss settlement
expenses to net earned premium ("loss ratio"); (ii) the ratio of
expenses incurred for commissions, premium taxes, administrative
and other underwriting expenses to net written premium ("expense
ratio"); and (iii) the ratio of dividends to policyholders to net
earned premium ("dividend ratio").  The GAAP combined ratio is
calculated in the same manner except that it is based on GAAP
amounts and the denominator for each component is net earned
premium.  When the combined ratio is under 100%, underwriting
results are generally considered profitable.  Conversely, when the
combined ratio is over 100%, underwriting results are generally
considered unprofitable.  The combined ratio does not reflect
investment income, federal income taxes or other non-operating
income or expense.  Harleysville Group's operating income is a
function of both underwriting results and investment income.

POOLING ARRANGEMENT

      The Company's property and casualty subsidiaries participate
in an intercompany pooling arrangement with the Mutual Company. 
The underwriting pool is intended to produce a more uniform and
stable underwriting result from year to year for all companies in
the pool than they would experience individually and to reduce the
risk of loss of any of the pool participants by spreading the risk
among all the participants.  Each company participating in the pool
has at its disposal the capacity of the entire pool, rather than
being limited to policy exposures of a size commensurate with its
own capital and surplus.  The additional capacity exists because
such policy exposures are spread among all the pool participants
which each have their own capital and surplus.  Regulation is
applied to the individual companies rather than to the pool.

                                          6

<PAGE>


      Pursuant to the terms of the pooling agreement with the Mutual
Company, each of the Company's subsidiary participants cedes
premiums, losses and expenses on all of its business to the Mutual
Company which, in turn, retrocedes to such subsidiaries a specified
portion of premiums, losses and expenses of the Mutual Company and
such subsidiaries.  Under the terms of the intercompany pooling
agreement which became effective January 1, 1986, Huron and HNJ
ceded to the Mutual Company all of their insurance business written
on or after January 1, 1986.  All of the Mutual Company's property
and casualty insurance business written or in force on or after
January 1, 1986,  was also included in the pooled business.  The
pooling agreement provides, however, that Harleysville Group is not
liable for any losses occurring prior to January 1, 1986.  The
pooling agreement does not legally discharge Harleysville Group
from its primary liability for the full amount of the policies
ceded.  However, it makes the Mutual Company liable to Harleysville
Group to the extent of the business ceded. 

      The following table sets forth a chronology of the changes
that have occurred in the pooling agreement since it became
effective on January 1, 1986.

      When pool participation percentages increased as described
above, cash and investments equal to the net increase in
liabilities assumed less a ceding commission related to the net
increase in the liability for unearned premiums, was transferred
from the Mutual Company to Harleysville Group.  See Note 3(a) of
the Notes to Consolidated Financial Statements.

      All premiums, losses, loss settlement expenses and other
underwriting expenses are prorated among the parties to the pooling
arrangement on the basis of their participation in the pool.  The
method of establishing reserves is set forth under "Business -
Reserves."  The pooling agreement may be amended or terminated by
agreement of the parties.  Termination may occur only at the end of
a calendar year.  The Company and the Mutual Company maintain a
coordinating committee which reviews and evaluates the pooling
arrangements  between the  Company  and the Mutual Company.  See
"Business-Relationship with the Mutual Company."  In evaluating
pool participation changes, the coordinating committee considers
current and proposed acquisitions, the relative capital positions
and revenue contributions of the pool participants, and growth
prospects and ability to access capital markets to support that
growth.  Harleysville Group does not intend to terminate its
participation in the pooling agreement.

     RESERVES.  Loss reserves are estimates at a given point in
time of what the insurer expects to pay to claimants for claims
occurring on or before such point in time, including claims which
have not yet been reported to the insurer.  These are estimates,
and it can be expected that the ultimate liability will exceed or
be less than such estimates.  During the loss settlement period,
additional facts regarding individual claims may become known, and
consequently it often becomes necessary to refine and adjust the
estimates of liability.

      Harleysville Group maintains reserves for the eventual payment
of losses and loss settlement expenses with respect to both
reported and unreported claims.  Loss settlement expense reserves
are intended to cover the ultimate costs of settling all claims,
including investigation and litigation costs relating to such
claims.  The amount of loss reserves for reported claims is based
primarily upon a case-by-case evaluation of the type of risk
involved and knowledge of the circumstances surrounding each claim
and the insurance policy provisions relating to the type of loss. 
The amounts of loss reserves for unreported claims and loss
settlement expense reserves are determined on the basis of
historical information by line of insurance as adjusted to current
conditions.  Inflation is implicitly provided for in the reserving
function through analysis of costs, trends and reviews of
historical reserving results.  Reserves are closely monitored and
are recomputed periodically by Harleysville Group and the Mutual
Company using new information on reported claims and a variety of
statistical techniques.  With the exception of reserves relating to
some workers compensation long-term disability cases, loss reserves
are not discounted.

      The following table sets forth the development of net reserves
for unpaid losses and loss settlement expenses from 1987 through
1997 for the pooled business of the Mutual Company and Harleysville
Group.  "Reserve for losses and loss settlement expenses" sets
forth the estimated liability for unpaid losses and loss settlement
expenses recorded at the balance sheet date for each of the
indicated years.  This liability represents the estimated amount of
losses and loss settlement expenses for claims arising in the
current and all prior years that are unpaid at the balance sheet
date, including losses incurred but not reported. 

      The "Reserves reestimated" portion of the table shows the
reestimated amount of the previously recorded liability based on
experience of each succeeding year.  The estimate is increased or
decreased as payments are made and more information becomes known
about the severity of remaining unpaid claims.  For example, the
1990 liability has developed a deficiency after seven years, in
that reestimated losses and loss settlement expenses are expected
to exceed the initial estimated liability established in 1990 of
$676.5 million by $12.8 million, or 1.9%.

      The "Cumulative amount of reserves paid" portion of the table
shows the cumulative losses and loss settlement expense payments
made in succeeding years for losses incurred prior to the balance
sheet date.  For example, the 1990 column indicates that as of
December 31, 1997, payments of $605.4 million of the currently
reestimated ultimate liability for losses and loss settlement
expenses had been made.

      The "Redundancy (deficiency)" portion of the table shows the
cumulative redundancy or deficiency at December 31, 1997 of the
reserve estimate shown on the top line of the corresponding column. 
A redundancy in reserves means that reserves established in prior
years exceeded actual losses and loss settlement expenses or were
reevaluated at less than the original reserved amount.  A
deficiency in reserves means that the reserves established in prior
years were less than actual losses and loss settlement expenses or
were reevaluated at more than the originally reserved amount.

      The following table includes all 1997 pool participants as if
they had participated in the pooling arrangement in all years
indicated except for acquired pool participant companies, which are
included from their date of acquisition.  Under the terms of the
pooling arrangement, Harleysville Group is not responsible for
losses on the pooled business occurring prior to January 1, 1986.

      Harleysville Group's reserves primarily are derived from those
established for the total pooled business.  The terms of the
pooling agreement provide that Harleysville Group is responsible
only for pooled losses incurred on or after the effective date,
January 1, 1986.  The GAAP loss reserve experience of Harleysville
Group, as reflected in its financial statements, is shown in the
following table which sets forth a reconciliation of beginning and
ending net reserves for unpaid losses and loss settlement expenses
for the years indicated for the business of Harleysville Group
only.

      Harleysville Group recognized a decrease in the provision for
insured events of prior years (favorable development) of $29.7, 
$35.0 and $10.9 million in 1997, 1996 and 1995, respectively.  The
favorable development in 1997 and 1996 primarily related to lower
than expected claim severity in the workers compensation and
automobile lines of business.  The 1995 favorable development
primarily related to lower than expected claim severity in workers
compensation.

     The following table sets forth the development of net reserves
for unpaid losses and loss settlement expenses for Harleysville
Group.  The effect of changes to the pooling agreement
participation is reflected in this table.  For example, the January
1, 1989 increase in Harleysville Group's pooling participation from
35% to 50% is reflected in the first line of the 1989 column. 
Amounts of assets equal to increases in net liabilities was
transferred to Harleysville Group from the Mutual Company in
conjunction with each respective pooling change.  The amount of the
assets transferred has been netted against and has reduced the
cumulative amounts paid for years prior to the pooling changes. 
For example, the 1988 column of the "Cumulative amount of reserves
paid" portion of the table reflects the assets transferred in
conjunction with the 1989 increase in the pooling percentage from
35% to 50% as a decrease netted in the "one year later" line.  The
cumulative amounts paid are reflected in this manner to maintain
comparability.  This is because when Harleysville Group pays claims
subsequent to the date of a pool participation increase, the
amounts paid are greater, however, the prior year's reserve amounts
are reflective of a lower pool participation percentage.  By
reflecting pooling participation increases in this manner, loss
development is not obscured.  Loss development reflects
Harleysville Group's share of the total pooled business loss
development since January 1, 1986 when Harleysville Group began
participation, plus loss development of any subsidiary not
participating in the pooling agreement.

     Loss development information for the total pooled business is
presented on pages 11 to 13 to provide greater analysis of
underlying claims development.

     REINSURANCE.  Harleysville Group follows the customary industry
practice of reinsuring a portion of its exposures and paying to the
reinsurers a portion of the premiums received on all policies. 
Insurance is ceded principally to reduce the net liability on
individual risks and to protect against catastrophic losses. 
Reinsurance does not legally discharge an insurer from its primary
liability for the full amount of the policies, although it does
make the assuming reinsurer liable to the insurer to the extent of
the reinsurance ceded.  Therefore, a ceding company is subject to
credit risk with respect to its reinsurers.

     The reinsurance described below is maintained for the Company's
subsidiaries and the Mutual Company and its wholly-owned
subsidiaries.  Reinsurance premiums and recoveries are allocated to
participants in the pooling agreement according to pooling
percentages.

     Reinsurance for property and auto physical damage losses is
currently maintained under a per risk excess of loss treaty
affording recovery to $4,250,000, above a retention of $750,000. 
Harleysville Group's 1998 pooling share of such recovery would be
$3,060,000 above a retention of $540,000.  In addition, the
Company's subsidiaries and the Mutual Company and its wholly-owned
subsidiaries are reinsured under a catastrophe reinsurance treaty
effective for one year from July 1, 1997 which provides coverage
for 85% of up to $147 million in excess of a retention of $20
million for any given catastrophe.  Harleysville Group's 1998
pooling share of this coverage would be 85% of up to $105.8 million
in excess of a retention of $14.4 million for any given
catastrophe.  Pursuant to the terms of the treaty, the maximum
recovery would be $125 million for any catastrophe involving an
insured loss equal to or greater than $167 million.  Harleysville
Group's 1998 pooling share of this maximum recovery would be $90
million for any catastrophe involving an insured loss of $120
million or greater.  The treaty includes reinstatement provisions
providing for coverage for a second catastrophe and requiring
payment of an additional premium in the event of a first
catastrophe occurring.  Harleysville Group has not purchased funded
catastrophe covers.

     Casualty reinsurance (including liability and workers
compensation) is currently maintained under an excess of loss
treaty affording recovery to $19,000,000 above a retention of
$1,000,000 each loss occurrence.  Harleysville Group's 1998 pooling
share of such recovery would be $13,680,000 above a retention of
$720,000.  In addition, there is reinsurance to protect
Harleysville Group from large workers compensation losses.  For
umbrella liability coverages, reinsurance protection up to
$4,000,000 is provided over a retention of $1,000,000. 
Harleysville Group's 1998 pooling share would provide for recovery
of $2,880,000 over a retention of $720,000.

                                         17

     Harleysville Group has a reinsurance agreement with Mutual
whereby, in 1998, Mutual reinsures accumulated catastrophe losses
in a quarter up to $16,200,000 in excess of $1,800,000 in return
for a reinsurance premium.  The agreement excludes catastrophe
losses resulting from earthquakes or hurricanes.

     The terms and charges for reinsurance coverage are typically
negotiated annually.  The reinsurance market is subject to
conditions which are similar to those in the direct property and
casualty insurance market, and there can be no assurance that
reinsurance will remain available to Harleysville Group to the same
extent and at the same cost currently maintained.

     Harleysville Group considers numerous factors in choosing
reinsurers, the most important of which is the financial stability
of the reinsurer.  Harleysville Group has not experienced any
material collectibility problems for its reinsurance recoverables.

     COMPETITION.  The property and casualty insurance industry is
highly competitive on the basis of both price and service.  There
are numerous companies competing for this business in the
geographic areas where Harleysville Group operates, many of which
are substantially larger and have considerably greater financial
resources than Harleysville Group.  In addition, because the
insurance products of Harleysville Group and the Mutual Company are
marketed exclusively through independent insurance agencies, most
of which represent more than one company, Harleysville Group faces
competition within each agency.

INVESTMENTS

     An important element of the financial results of Harleysville
Group is the return on invested assets.  An investment objective of 
Harleysville Group is to maintain a widely diversified fixed
maturities portfolio structured to maximize after-tax investment
income while minimizing credit risk through investments in high
quality instruments.  An objective also is to provide adequate
funds to pay claims without forced sales of investments.  From 1994
to 1997, Harleysville Group invested $64 million in equity
securities with the objective of capital appreciation.  At December
31, 1997, the investment portfolio did not contain any securities
that were rated at less than investment grade, and it did not
contain any real estate or mortgage loans.

     Harleysville Group has adopted and follows an investment
philosophy which precludes the purchase of non-investment grade
fixed income securities.  However, due to uncertainties in the
economic environment, it is possible that the quality of
investments held in Harleysville Group's portfolio may change.

      Harleysville Group invests in both taxable and tax-exempt
securities as part of its strategy to maximize after-tax income. 
Such strategy considers, among other factors, the impact of the
alternative minimum tax.  Tax-exempt bonds made up approximately  
45%, 45% and 37% of the total investment portfolio at December 31,
1997, 1996 and 1995, respectively.

REGULATION

      Insurance companies are subject to supervision and regulation
in the states in which they transact business.  Such supervision
and regulation relate to numerous aspects of an insurance company's
business and financial condition.  The primary purpose of such
supervision and regulation is the protection of policyholders.  The
extent of such regulation varies, but generally derives from state
statutes which delegate regulatory, supervisory and administrative
authority to state insurance departments.  Accordingly, the
authority of the state insurance departments includes the
establishment of standards of solvency which must be met and
maintained by insurers, the licensing to do business of insurers
and agents, the nature of and limitations on investments, premium
rates for property and casualty insurance, the provisions which
insurers must make for current losses and future liabilities, the
deposit of securities for the benefit of policyholders and the
approval of policy forms.  Such insurance departments also conduct
periodic examinations of the affairs of insurance companies and
require the filing of annual and other reports relating to the
financial condition of insurance companies.

      All of the states in which Harleysville Group and the Mutual
Company do business have guaranty fund laws under which insurers
doing business in such states can be assessed up to 2% of annual
premiums written by the insurer in that state in order to fund
policyholder liabilities of insolvent insurance companies.  Under
these laws in general, an insurer is subject to assessment,
depending upon its market share of a given line of business, to
assist in the payment of policyholder and third party claims
against insolvent insurers.  During the five years ended December
31, 1997, the amount of such insolvency assessments paid by
Harleysville Group and the Mutual Company was not material.

      State laws also require Harleysville Group to participate in
involuntary insurance programs for automobile insurance, as well as
other property and casualty lines, in states in which Harleysville
Group operates.  These programs include joint underwriting
associations, assigned risk plans, fair access to insurance
requirements ("FAIR") plans, reinsurance facilities and wind storm
plans.  These state laws generally require all companies that write
lines covered by these programs to provide coverage (either
directly or through reinsurance) for insureds who cannot obtain
insurance in the voluntary market.  The legislation creating these
programs usually allocates a pro rata portion of risks attributable
to such insureds to each company on the basis of direct written
premiums or the number of automobiles insured.  Generally, state
law requires participation in such programs as a condition to doing
business.  The loss ratio on insurance written under involuntary
programs generally has been greater than the loss ratio on
insurance in the voluntary market.

                                         21

      State insurance holding company acts regulate insurance
holding company systems.  Each insurance company in the holding
company system is required to register with the insurance
supervisory agency of its state of domicile and furnish certain
information concerning the operations of companies within the
holding company system that may materially affect the operations,
management or financial condition of the insurer within the system. 
Such laws further require disclosure of material transactions
including the payment of "extraordinary dividends" from the
insurance subsidiaries to the Company.

      Insurance holding company acts require that all transactions
within the holding company system affecting the Mutual Company and
the Company's insurance subsidiaries must be fair and equitable. 
Further, approval of the applicable insurance commissioner is
required prior to the consummation of transactions affecting the
control of an insurer.

      The property and casualty insurance industry has been subject
to significant public scrutiny and comment primarily due to
concerns regarding solvency issues, rising insurance costs, and the
industry's methods of operations.  Accordingly, new regulations and
legislation are being proposed to bring the insurance industry
under federal control; to strengthen state oversight, particularly
in the field of solvency and investments; to further restrict an
insurer's ability to underwrite and price risks; and to impose new
taxes and assessments.  It is not possible to predict whether, in
what form or in what jurisdictions any of these proposals might be
adopted or the effect, if any, on the Company.

      The Company's insurance subsidiaries are restricted by the
insurance laws of their respective states of domicile as to the
amount of dividends they may pay to the Company without the prior
approval of the respective state regulatory authorities. 
Generally, the maximum dividend that may be paid by an insurance
subsidiary during any year without prior regulatory approval is
limited to a stated percentage of that subsidiary's statutory
surplus as of a certain date, or adjusted net income of the
subsidiary, for the preceding year.   Applying current regulatory
restrictions as of December 31, 1997, $24,061,000 would be
available for distribution to Harleysville Group Inc. without prior
approval until September 30, 1998, after which $57,808,000 would be
available for distribution to Harleysville Group Inc. without prior
approval.  The Company's insurance subsidiaries paid dividends of
$31.7 million to Harleysville Group Inc. in 1997.  No dividends
were paid in 1996 or 1995.

      The National Association of Insurance Commissioners has
adopted risk-based capital (RBC) standards that require insurance
companies to calculate and report statutory capital and surplus
needs based on a formula measuring underwriting, investment and
other business risks inherent in an individual company's
operations.  These RBC standards have not affected the operations
of Harleysville Group since each of the Company's insurance
subsidiaries has statutory capital and surplus in excess of RBC
requirements.

RELATIONSHIP WITH THE MUTUAL COMPANY

      Harleysville Group's operations are interrelated with the
operations of the Mutual Company due to the pooling arrangement and
other factors.  The Mutual Company owns approximately 54% of
Harleysville Group.  Harleysville Group employees provide a variety
of services to the Mutual Company and its wholly-owned
subsidiaries.  The cost of facilities and employees required to
conduct the business of both companies is charged on a cost-
allocated basis.  Harleysville Group also manages the operations of
the Mutual Company and its wholly-owned subsidiaries pursuant to a
management agreement which commenced January 1, 1993 under which
Harleysville Group receives a management fee.  Harleysville Group
also manages the operations of Berkshire Mutual Insurance Company,

                                         23

<PAGE>


a small property and casualty insurance company, pursuant to a
management services agreement.  Harleysville Group received $6.0
million, $6.6 million and $6.9 million for the years ended December
31, 1997, 1996 and 1995, respectively, for all such management
services.

      All of the Company's officers are officers of the Mutual
Company, and five of the Company's eight directors are directors of
the Mutual Company.  A coordinating committee exists to review and
evaluate the pooling agreement and is responsible for matters
involving actual or potential conflicts of interest between the two
companies.  The decisions of the coordinating committee are binding
on the two companies.  No intercompany transaction can be
authorized by the coordinating committee unless the Company's
committee members conclude that such transaction is fair and
equitable to Harleysville Group.  The coordinating committee
consists of seven non-employee directors, three from Harleysville
Group Inc. and three from the Mutual Company all of whom are not
members of both Boards and one, the Chairman, who is a member of
both Boards.  For information concerning the members of the
coordinating committee, see "Board and Committee Meetings" section
on pages 5 to 6 of the Company's proxy statement relating to the
annual meeting of the shareholders to be held April 22, 1998 which
is incorporated by reference in this Form 10-K Report.

      The Mutual Company leases the home office from Harleysville
Group with which it shares most of the facility.  Rental income
under the lease was $2,754,000 for 1997 and 1996 and $2,750,000 for
1995.  Harleysville Group believes that the lease terms are no less
favorable to it than if the property were leased to a non-
affiliate.

        In connection with the acquisition of Mid-America and New
York Casualty, the Company borrowed approximately $18.5 million
from the Mutual Company.  See Note 8 of the Notes to Consolidated
Financial Statements.  For additional information with respect to
transactions with the Mutual Company, see Note 3 of the Notes to
Consolidated Financial Statements.

EMPLOYEES

      All employees are paid by Harleysville Group and, accordingly,
are considered to be employees of Harleysville Group.  As of
December 31, 1997, there were 2,732 employees.  They provide a
variety of services to the Mutual Company and its wholly-owned
subsidiaries.  See "Business-Relationship with the Mutual Company"
and Note 3(c) of the Notes to Consolidated Financial Statements.

ITEM 2. PROPERTIES.
- ------- ----------

      The buildings which house the headquarters of Harleysville
Group and the Mutual Company are leased by the Mutual Company from
a subsidiary of Harleysville Group.  See "Business-Relationship
with the Mutual Company."  The Mutual Company charges Harleysville
Group for an appropriate portion of the rent under an intercompany
allocation agreement.  The buildings containing the headquarters of
Harleysville Group and the Mutual Company have approximately
220,000 square feet of office space.  Harleysville Group also rents
office facilities in certain of the states in which it does
business.


ITEM 3. LEGAL PROCEEDINGS.
- ------- -----------------

      Harleysville Group is a party to numerous lawsuits arising in
the ordinary course of its insurance business.  Harleysville Group
believes that the resolution of these lawsuits will not have a
material adverse effect on its financial condition.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
- ------- ---------------------------------------------------

      No matter was submitted during the fourth quarter of 1997 to
a vote of holders of the Company's Common Stock.

                               TO
              HARLEYSVILLE MUTUAL INSURANCE COMPANY
                     HURON INSURANCE COMPANY
          HARLEYSVILLE INSURANCE COMPANY OF NEW JERSEY

               PROPORTIONAL REINSURANCE AGREEMENT
               ----------------------------------

     This Ninth Amendment to the proportional Reinsurance Agreement
is entered into by and between HARLEYSVILLE INSURANCE COMPANY
("HMIC"), HURON INSURANCE COMPANY ("HURON"), HARLEYSVILLE INSURANCE
COMPANY OF NEW JERSEY ("HICNJ"), HARLEYSVILLE-ATLANTIC INSURANCE
COMPANY ("HAIC"), WORCESTER INSURANCE COMPANY ("WIC"), MID-AMERICA
INSURANCE COMPANY ("MAIC"), NEW YORK CASUALTY INSURANCE COMPANY
("NYC), GREAT OAKS INSURANCE COMPANY ("GOIC"), PENNLAND INSURANCE
COMPANY ("PENNLAND"), LAKES STATES INSURANCE COMPANY ("LSIC") AND
MINNESOTA FIRE AND CASUALTY COMPANY ("MF&C").

     The purpose of this Amendment is to amend the Proportional
Reinsurance Agreement ("the Agreement") between Harleysville Mutual
Insurance Company, Huron Insurance Company, Harleysville Insurance
Company of New Jersey, Harleysville-Atlantic Insurance Company,
Worcester Insurance Company, Mid-America Insurance Company, New
York Casualty Insurance Company, Great Oaks Insurance Company,
Pennland Insurance Company and Lake States Insurance Company dated
April 7, 1986, and amended June 30, 1987, December 30, 1988,
November 22, 1989, March 19, 1990, August 9, 1993 (with revision
dated August 2, 1994), March 16, 1995, March 18, 1986, and March 3,
1997 (with Addendum dated March 3, 1997), in which those companies
created a common risk-sharing pool for their underwriting
operations, to address business assumed by HMIC from Boyertown
Mutual Insurance Company ("Boyertown") prior to its renewal at
Harleysville's rates, and to provide for the participation of a new
subsidiary, MF&C.

                                1


<PAGE>

     In consideration of the mutual agreements hereinafter set
forth and contained in the Agreement, the parties hereby agree as
follows:

     1.  HMIC has entered into a Liability and Asset Transfer with
         Boyertown, which is only licensed in the Commonwealth of
         Pennsylvania, whereby HMIC will assume the assets and
         liabilities, policy and corporate, of Boyertown, which
         assumption is being undertaken with the approval of the
         Pennsylvania Insurance Department because of Boyertown's
         precarious financial condition.  Therefore until such
         policies are renewed by HMIC or another company which is
         a participant in the Agreement, such business shall be
         excluded from this Agreement and be solely a liability or
         asset of HMIC.

     2.  MF&C is a subsidiary of HMIC as that term is defined in
         Paragraph 1.6 of Part I of the Proportional Reinsurance
         Agreement.

     3.  MF&C shall participate in the Agreement as of January 1,
         1998.

     4.  As of January 1, 1998, the proportionate share of all
         participants shall be as set forth in Exhibit I to this
         Ninth Amendment.

     5.  All other terms and conditions of the Proportional
         Reinsurance Agreement, as amended from time to time, shall
         remain the same and apply to MF&C, except the term
         "opening of business" found in Part I, Paragraph 1.1 shall

[FN]
<F1>  The Company's insurance subsidiaries participate in an underwriting
      pooling arrangement with Mutual.  Harleysville Group's participation was
      60% from January 1, 1993 to December 31, 1995 and 65% for 1996.  Lake
      States was acquired as of November 1, 1993, and was not a participant in
      the pool through 1996.  As of January 1, 1997, Harleysville Group's
      participation increased to 70% and Lake States became a participant in
      the pool.  Minnesota Fire was acquired as of October 1, 1997 and became
      a participant in the pool as of January 1, 1998 at which time
      Harleysville Group's participation increased to 72%.  See "Management's
      Discussion and Analysis of Results of Operations and Financial
      Condition" and Note 3(a) of the Notes to Consolidated Financial
      Statements.  The presentation of earnings per share amounts prior to
      1997 reflect retroactive application of a new accounting standard.  See
      Note 1.  For 1993, net income is net of a $281,000 charge for the
      cumulative effect of accounting changes, net of income taxes.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS
                         OF OPERATIONS AND FINANCIAL CONDITION

RESULTS OF OPERATIONS

       Harleysville Group underwrites property and casualty
insurance, including auto, homeowners, commercial multi-peril,
workers compensation and other lines of business, that is marketed
primarily in the eastern and midwestern United States through
independent agents.  The Company's property and casualty
subsidiaries participate in a pooling agreement with Mutual.  The
pooling agreement provides for the allocation of premiums, losses,
loss settlement expenses and underwriting expenses between
Harleysville Group and Mutual.  Harleysville Group is not liable
for any pooled losses occurring prior to January 1, 1986, the date
the pooling agreement became effective.  Beginning January 1, 1996,
Harleysville Group's participation in the pooling agreement
increased from 60% to 65% and Pennland Insurance Company
(Pennland), a wholly-owned subsidiary of Mutual that writes
Pennsylvania personal automobile policies, became a participant in
the pooling agreement.  Lake States was not a participant in the
pooling agreement in 1996 or 1995.  Beginning January 1, 1997,
Harleysville Group's participation increased to 70% and Lake States
became a participant in the pooling arrangement.  Minnesota Fire
was acquired as of October 1, 1997 and became a participant in the
pooling agreement as of January 1, 1998 at which time Harleysville
Group's participation increased to 72%.

       When the Company's subsidiaries' pooling participation
increases, there is a larger retrocession of this pooled business
from Mutual.  Through this retrocession, Harleysville Group is
assuming a larger share of premiums, losses and expenses for
current and future periods originating both from its subsidiaries
and Mutual.  An increase in Harleysville Group's pooling
participation results in a larger share of the pooled liabilities
being assumed by Harleysville Group.  Cash and investments are
received by Harleysville Group equal to this greater share of loss
reserves, unearned premiums and other insurance liabilities
(primarily commissions and premium taxes) less a ceding commission
based on acquisition costs related to unearned premiums.  An
increase in pool participation also increases Harleysville Group's
leverage and exposure to adverse development.  Only balance sheet
entries have been made as of the date of changes in pool
participation and no gain or loss has been recognized on the
transactions.

       Historically, Harleysville Group's results of operations have
been influenced by factors affecting the property and casualty
insurance industry in general.  The operating results of the U.S.
property and casualty insurance industry have been subject to
significant variations due to competition, weather, catastrophic
events, regulation, general economic conditions, judicial trends,
fluctuations in interest rates and other changes in the investment
environment.

difficult to attract and retain properly priced personal and
commercial lines business.  Harleysville Group's premium growth and
underwriting results have been, and continue to be, affected by
this market condition.  It is management's policy to maintain its
underwriting standards, even at the expense of premium growth.


       1997 COMPARED TO 1996

       Premiums earned increased $9.7 million for the year ended
December 31, 1997.  Of such increase, $9.6 million was due to the
acquisition of Minnesota Fire.  The change in pool participation
did not materially affect premiums earned.  However, effective
January 1, 1997, 30% of Lake States' business was ceded to and
retained by Mutual and an additional 5% of the pooled business was
assumed from Mutual.

       Investment income increased $3.8 million for the year ended
December 31, 1997 primarily resulting from an increase in invested
assets provided by operating cash flow including $29.0 million from
a cash transfer received for various insurance liabilities assumed
January 1, 1997 in connection with the increase in Harleysville
Group's pool participation.  Also, invested assets increased by
$26.4 million due to the October 1, 1997 acquisition of Minnesota
Fire.  

       Realized investment gains increased $3.4 million for the year
ended December 31, 1997 primarily resulting from sales of equity
securities at greater gains.

       Income before income taxes increased $35.9 million for the
year ended December 31, 1997 primarily due to improved underwriting
results and the higher investment income and realized investment
gains.  Harleysville Group's combined ratio determined under
generally accepted accounting principles (GAAP) decreased to 103.6%
for the year ended December 31, 1997 from 108.4% for the year ended
December 31, 1996.  The 1996 results were adversely affected by two
hurricanes that struck the North Carolina coast and a blizzard
which, together, resulted in losses of $28.2 million ($0.66 per
basic share after taxes) and adversely affected Harleysville
Group's 1996 combined ratio by 4.6 points.  Excluding this impact,
the GAAP combined ratio improved 0.2 points primarily due to
improved results in the personal automobile line of business.

       1997 COMPARED TO 1996 (CONTINUED)

       Harleysville Group recognized favorable development in the
provision for insured events of prior years of $29.7 million and
$35.0 million in 1997 and 1996, respectively.  The decreased
favorable development primarily related to a smaller variance from
expected claim severity in the automobile lines of business.

       The 1997 effective tax expense rate increased to 19.6%
compared to 8.6% in 1996 primarily due to tax-exempt investment
income comprising a lower proportion of income before income taxes
in 1997.

       Weather-related events have impacted Harleysville Group's
results over the past several years.  Harleysville Group is
attempting to reduce the impact of catastrophes by achieving
greater geographic distribution of risks, reducing exposure in
catastrophe-prone areas and through reinsurance.  Effective January
1, 1997, Harleysville Group entered into a reinsurance agreement
with Mutual whereby Mutual reinsures accumulated catastrophe losses
in a quarter up to $15,750,000 ($16,200,000 in 1998) in excess of
$1,750,000 ($1,800,000 in 1998) in return for a reinsurance
premium.  The agreement excludes catastrophe losses resulting from
earthquakes or hurricanes.  Under this agreement, Harleysville
Group ceded to Mutual premiums earned of $2.6 million and losses
incurred of $1.6 million for 1997.  Effective for one year from
July 1, 1997, the Company's subsidiaries, and Mutual and its
wholly-owned subsidiaries are reinsured under a catastrophe
reinsurance treaty that provides coverage for 85% of up to $147
million in excess of a retention of $20 million for any given
catastrophe.  Harleysville Group's 1998 pooling share of this
coverage would be 85% of up to $105.8 million in excess of a
retention of $14.4 million for any given catastrophe.  Accordingly,
pursuant to the terms of the treaty, the maximum recovery would be
$125 million for any catastrophe involving an insured loss of $167
million or greater.  Harleysville Group's 1998 pooling share of
this maximum recovery would be $90 million for any catastrophe
involving an insured loss of $120 million or greater.  The treaty
includes reinstatement provisions providing for coverage for a
second catastrophe and requiring payment of an additional premium
in the event of a first catastrophe occurring.

       1996 COMPARED TO 1995

       Premiums earned increased $138.2 million for the year ended
December 31, 1996.  Of such increase, $76.7 million was due to the
increased pooling participation.  Excluding the effect of this
change, the premiums earned from pooled business increased $30.5
million for the year ended December 31, 1996 due to an increase in
commercial lines business.  The remaining increase of $31.0 million
was due to growth in Lake States, primarily from its expansion into
the neighboring states of Indiana, Illinois and Wisconsin.

       Investment income increased $9.6 million for the year ended
December 31, 1996 resulting from an increase in invested assets. 
Such increase was primarily provided by a $117.8 million cash
transfer received for various insurance liabilities assumed January
1, 1996 in connection with the increase in Harleysville Group's
pool participation.

       Realized investment gains increased $0.9 million for the year
ended December 31, 1996 primarily resulting from sales of equity
securities.

       Income before income taxes decreased $21.3 million for the
year ended December 31, 1996 primarily due to higher losses from
severe weather, partially offset by the higher investment income
and realized investment gains.  Harleysville Group's GAAP combined
ratio increased to 108.4% for the year ended December 31, 1996 from
104.0% for the year ended December 31, 1995.

       The 1996 results were adversely affected by Hurricanes Fran
and Bertha that both struck the North Carolina coast and resulted
in losses of $13.0 million.  In January 1996, a blizzard and
related storms resulted in losses of $15.2 million.  Together,
these losses totaled $28.2 million ($0.66 per basic share after
taxes) and adversely affected Harleysville Group's 1996 combined
ratio by 4.6 points.  Excluding this impact, the GAAP combined
ratio improved 0.2 points due to improved results in the personal
automobile line of business.

       Harleysville Group recognized favorable development in the
provision for insured events of prior years of $35.0 million and
$10.9 million in 1996 and 1995, respectively.  The increase relates
to lower than expected claim severity in the workers compensation
and automobile lines of business.

       The 1996 effective tax expense rate declined to 8.6% compared
to 21.5% in 1995 primarily due to tax-exempt investment income
comprising a higher proportion of income before income taxes in
1996.

       YEAR 2000

       Harleysville Group is in the process of comprehensively
assessing and modifying, where necessary, its computer applications
to ensure their functionality with respect to the year 2000
millennium change.  This process began in 1996 with an assessment
of the basic transaction processing systems, which include the
policy issuance, billing and claims systems.  The modifications of
these systems is planned to be completed and tested during the
second half of 1998.  Currently, Harleysville Group is completing
detailed plans for the remaining work to be done.  As most of
Harleysville Group's computer systems have been internally
developed, Harleysville Group primarily is utilizing internal
resources through redeployment of existing information technology
resources.  Costs incurred have not been material and, at present,
are not expected to be material in any single future year.

       Year 2000 computer problems create risk for Harleysville Group
because of unforeseen problems in computer systems of its own and
of third parties with whom Harleysville Group does business. 
Failure of the Harleysville Group or third party computer systems
could have a material impact on Harleysville Group's ability to
conduct its business.

       Harleysville Group is in the process of reviewing the
coverages provided under insurance policies it underwrites to
evaluate the potential impact on future results of operations, if
any, of year 2000 computer problems.


       NEW ACCOUNTING STANDARDS

       In 1997, Statement of Financial Accounting Standards (SFAS)
No. 130, "Comprehensive Income," was issued and established
standards for the reporting and disclosure of comprehensive income
and its components (revenues, expenses, gains and losses).  The
statement requires that all items that are required to be
recognized under accounting standards as components of
comprehensive income be reported in a financial statement that is
displayed with the same prominence as other financial statements. 
The statement requires that an enterprise (a) classify items of
other comprehensive income by their nature in a financial statement
and (b) display the accumulated balance of other comprehensive
income separately from retained earnings and additional paid-in
capital in the equity section of a statement of financial position. 
The statement is effective for fiscal years beginning after
December 31, 1997.  Harleysville Group will adopt the statement in
1998.

       NEW ACCOUNTING STANDARDS (CONTINUED)

       In 1997, SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," was issued and established
standards for the way public business enterprises report
information about operating segments in annual financial 
statements.  The statement requires that those enterprises report 
selected information about operating segments in interim financial
reports issued to shareholders.  It also establishes standards for
related disclosures about products and services, geographic areas
and major customers.  The statement is effective for fiscal years
beginning after December 15, 1997.  Harleysville Group is in the
process of determining the effect of this statement upon its
financial reporting requirements. 


       LIQUIDITY AND CAPITAL RESOURCES

       Liquidity is a measure of the ability to generate sufficient
cash to meet cash obligations as they come due.  Harleysville
Group's primary sources of cash are premium income, investment in-
come and maturing investments.  Cash outflows can be variable
because of uncertainties regarding settlement dates for liabilities
for unpaid losses and because of the potential for large losses
either individually or in the aggregate.  Accordingly, Harleysville
Group maintains investment and reinsurance programs generally
intended to provide adequate funds to pay claims without forced
sales of investments.  Harleysville Group models its exposure to
catastrophes and has the ability to pay claims without selling held
to maturity securities even for events having a low probability
(less than 1%).  In recent years, Harleysville Group has experi- 
enced more frequent catastrophes than in prior years and has been
able to pay claims without liquidating any investments.  Harleys-
ville Group has also considered scenarios of declines in revenue
and increases in loss payments and has the ability to meet cash
requirements under such scenarios without selling held to maturity
securities.  Harleysville Group's policy with respect to fixed
maturity investments is to purchase only those that are of
investment grade quality.

       Net cash provided by operating activities was $89.8 million
and $207.0 million for 1997 and 1996, respectively.  The decrease
in net cash provided by operating activities in 1997 primarily
reflects the effect of amendments to the pooling agreement with
Mutual.  Cash transfers of $29.0 million and $117.8 million were
received effective January 1, 1997 and 1996, respectively, by
Harleysville Group related to the various liabilities assumed in
connection with such amendments.

       LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

       Net cash used by investing activities was $84.9 million and
$206.6 million for 1997 and 1996, respectively.  The lower amount
in 1997 reflects the investment of the cash provided by operating
activities.

       Financing activities used net cash of $5.6 million in 1997
compared to $1.5 million in 1996.  The change was primarily due to
an increase in dividend payments and a decrease in the issuance of
common stock as Mutual did not reinvest its dividend from the
Company.

       The Company maintained $3.8 million of cash and marketable
securities at the holding company level at December 31, 1997, which
is available for general corporate purposes including dividends,
debt service, capital contributions to subsidiaries and
acquisitions.  Harleysville Group has no material commitments for
capital expenditures as of December 31, 1997.

       As a holding company, the Company's principal source of cash
for the payment of dividends is dividends from its subsidiaries. 
The Company's insurance subsidiaries are subject to state laws that
restrict their ability to pay dividends.

       Applying the current regulatory restrictions as of December
31, 1997, $24.1 million would be available for distribution to the
Company by its subsidiaries without prior regulatory approval until
September 30, 1998, after which $57.8 million would be available
for distribution to the Company without prior approval.  In 1997,
the Company's insurance subsidiaries paid dividends of $31.7
million to the Company which was used to purchase Minnesota Fire. 
See the Business-Regulation section of the Company's 1997 Form 10-K 
which includes a reconciliation of net income and shareholders'
equity as determined under statutory accounting practices to net
income and shareholders' equity as determined in accordance with
generally accepted accounting principles. Also, see Note 9 of the
Notes to Consolidated Financial Statements. 

       The National Association of Insurance Commissioners has
adopted risk-based capital (RBC) standards that require insurance
companies to calculate and report statutory capital and surplus
needs based on a formula measuring underwriting, investment and
other business risks inherent in an individual company's
operations.  These RBC standards have not affected the operations
of Harleysville Group since each of the Company's insurance
subsidiaries has statutory capital and surplus in excess of RBC
requirements.

       LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

       Harleysville Group had off-balance-sheet credit risk related
to $59.0 million of premium balances due to Mutual from agents at
December 31, 1997.


       IMPACT OF INFLATION

       Property and casualty insurance premiums are established
before the amount of losses and loss settlement expenses, or the
extent to which inflation may affect such expenses, are known. 
Consequently, Harleysville Group attempts, in establishing rates,
to anticipate the potential impact of inflation.  In the past,
inflation has contributed to increased losses and loss settlement
expenses.

       Principles of Consolidation and Basis of Presentation

       The accompanying financial statements include the accounts of
Harleysville Group prepared in conformity with generally accepted
accounting principles, which differ in some respects from those
followed in reports to insurance regulatory authorities.  All
significant intercompany balances and transactions have been
eliminated in consolidation.

       The preparation of financial statements in conformity with
generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the
reported amounts of revenues and expenses during the reporting
period.  Actual results could differ from these estimates.

       INVESTMENTS

       Accounting for fixed maturities depends on their
classification as held to maturity, available for sale or trading. 
Fixed maturities classified as available for sale are carried at
fair value, with unrealized gains or losses credited or charged
directly to a separate component of shareholders' equity.

       POLICIES (CONTINUED)

       INVESTMENTS (CONTINUED)

       Investments in fixed maturities that are classified as held to
maturity are carried at amortized cost.  Equity securities are
carried at fair value.  There were no investments classified as
trading.  Short-term investments are recorded at cost, which
approximates fair value.

       Realized gains and losses on sales of investments are
recognized in net income on the specific identification basis. 
Unrealized investment gains or losses, net of applicable income
taxes, are reflected directly in shareholders' equity and,
accordingly, have no effect on net income.

       PREMIUMS

       Premiums are recognized as revenue ratably over the terms of
the respective policies.  Unearned premiums are calculated on the
monthly pro rata basis.

       POLICY ACQUISITION COSTS

       Policy acquisition costs, such as commissions, premium taxes
and certain other underwriting and agency expenses that vary with
and are directly related to the production of business, are
deferred and amortized over the effective period of the related
insurance policies.  The method followed in computing deferred
policy acquisition costs limits the amount of such deferred costs
to their estimated realizable value, which gives effect to the
premium to be earned, related investment income, losses and loss
settlement expenses, and certain other costs expected to be
incurred as the premium is earned.

       LOSSES AND LOSS SETTLEMENT EXPENSES

       The liability for losses and loss settlement expenses
represents estimates of the ultimate unpaid cost of all losses
incurred which includes the gross liabilities to Harleysville
Group's policyholders plus the net liability to Mutual under the
pooling agreement.  See Note 3(a).  Such estimates may be more or
less than the amounts ultimately paid when the claims are settled. 
These estimates are periodically reviewed and adjusted as
necessary; such adjustments are reflected in current operations.

       STOCK-BASED COMPENSATION

       Stock-based compensation plans are accounted for under the
provisions of Accounting Principles Board (APB) Opinion No. 25,
"Accounting for Stock Issued to Employees," and related
interpretations.  As such, compensation expense would be recorded
on the date of a stock option grant only if the current market
price of the underlying stock exceeded the exercise price.  For
disclosure purposes, pro forma net income and earnings per share
are provided in accordance with Statement of Financial Accounting
Standards (SFAS) No. 123, "Accounting for Stock-Based
Compensation."  

       PROPERTY AND EQUIPMENT

       Property and equipment are carried at cost less accumulated
depreciation.  Depreciation is calculated primarily on the
straight-line basis over the estimated useful lives of the assets
(40 years for buildings and three to 15 years for equipment).

       INCOME TAXES

       Deferred income tax assets and liabilities are recognized for
the future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and
liabilities and their respective tax bases.  


       EARNINGS PER SHARE

       In 1997, SFAS No. 128 "Earnings Per Share," was issued and
replaced the calculation of primary and fully diluted earnings per
share with basic and diluted earnings per share.  Basic earnings
per share are computed by dividing earnings by the weighted-average
number of common shares outstanding during the year.  For
Harleysville Group, basic and primary earnings per share do not
differ for the years presented.  Diluted earnings per share
includes the dilutive effect of the stock option and stock purchase
plans described in Note 11.  Share and per share amounts have been
retroactively adjusted to reflect a two-for-one stock split in
1997.

 2 - ACQUISITION

       On October 1, 1997 Harleysville Group Inc. acquired Minnesota
Fire, a property and casualty insurance company conducting business
primarily in Minnesota and neighboring states, for $33,986,000  in
cash.  The acquisition was accounted for as a purchase and resulted
in goodwill of $7,028,000 which is being amortized over 40 years on
the straight-line basis.  The consolidated financial statements
include the results of operations of Minnesota Fire from the date
of acquisition.  Pro forma consolidated results of operations are
not presented because the amounts are not materially different from
Harleysville Group's historical results.  Supplemental cash flow
information for the acquisition is as follows:

 3 - TRANSACTIONS WITH AFFILIATES

       (a) UNDERWRITING

       The insurance subsidiaries participate in a reinsurance
pooling agreement with Mutual whereby such subsidiaries cede to
Mutual all of their insurance business and assume from Mutual an
amount equal to their participation in the pooling agreement.  All
losses and loss settlement expenses and other underwriting expenses
are prorated among the parties on the basis of participation in the
pooling agreement.  The agreement pertains to all insurance
business written or earned on or after January 1, 1986. 
Harleysville Group's participation in the pooling agreement was 60%
for 1995.  Beginning January 1, 1996, Harleysville Group's
participation increased to 65% and Pennland Insurance Company
(Pennland), a subsidiary of Mutual, became a participant in the
pooling arrangement.  Pennland writes Pennsylvania personal
automobile business which had earned premiums of $63.0 million in
1996.  Lake States was not a participant in the pooling agreement
in 1996 or 1995.  Beginning January 1, 1997, Harleysville Group's
participation increased to 70% and Lake States became a participant
in the pooling arrangement.  Minnesota Fire was acquired as of
October 1, 1997 and became a participant in the pool as of January
1, 1998, at which time Harleysville Group's participation increased
to 72%.  In connection with these changes in pool participation,
Harleysville Group received cash and investments from Mutual of
$14,962,000, $29,002,000 and $117,800,000, which related to the

1996, respectively.  These liabilities consist of the following at
January 1:

       Because this agreement does not relieve Harleysville Group of
primary liability as the originating insurer, there is a
concentration of credit risk arising from business ceded to Mutual. 
However, the reinsurance pooling agreement provides for the right
of offset and the net balance with Mutual is a liability at
December 31, 1997 and 1996.  Mutual has an A. M. Best rating of "A"
(Excellent) and, in accordance with certain state regulatory
requirements, maintained $334.0 million (fair value) of investments
in a trust account to secure liabilities under the reinsurance
pooling agreement at December 31, 1997.

       The following amounts represent reinsurance transactions
between Harleysville Group and Mutual under the pooling
arrangement:

 3 - TRANSACTIONS WITH AFFILIATES (CONTINUED)

       (a) UNDERWRITING (CONTINUED)

       Effective January 1, 1997, Harleysville Group entered into a
reinsurance agreement with Mutual whereby Mutual reinsures
accumulated catastrophe losses in a quarter up to $15,750,000
($16,200,000 in 1998) in excess of $1,750,000 ($1,800,000 in 1998)
in return for a reinsurance premium.  The agreement excludes
catastrophe losses resulting from earthquakes or hurricanes, and
supplements the existing external catastrophe reinsurance program. 
Under this agreement, Harleysville Group ceded to Mutual premiums
earned of $2,615,000 and losses incurred of $1,616,000 for 1997.

       (b) PROPERTY

       Harleysville Ltd. leases the home office to Mutual which
shares most of the facility with Harleysville Group.  Rental income
under the lease was $2,754,000, for both 1997 and 1996 and
$2,750,000 for 1995 and is included in other income after
elimination of intercompany amounts of $1,639,000, $1,552,000 and
$1,405,000 in 1997, 1996 and 1995, respectively.

       (c) MANAGEMENT AGREEMENTS

       Harleysville Group Inc. received $5,992,000, $6,628,000 and
$6,944,000 of management fee income in 1997, 1996 and 1995,
respectively, under agreements whereby Harleysville Group Inc.
provides management services to Mutual and other affiliates.

       (d) INTERCOMPANY BALANCES

       Intercompany balances are created primarily from the pooling
arrangement (settled quarterly), allocation of common expenses,
collection of premium balances and payment of claims (settled
monthly).  No interest is charged or received on intercompany
balances due to the timely settlement terms and nature of the
items.  Interest expense on the loan from Mutual described in Note
8 was $1,275,000, $1,212,000 and $1,360,000 in 1997, 1996 and 1995,
respectively.

       Harleysville Group had off-balance-sheet credit risk related
to approximately $59,000,000 of premium balances due to Mutual from
agents at both December 31, 1997 and 1996.

       During 1995, Harleysville Group sold Kmart Corp. bonds that
had been classified as held to maturity due to a significant
deterioration in the issuer's creditworthiness.  These bonds had an
amortized cost of $4,690,000, and the sale resulted in a realized
gain of $76,000.  There were no other sales from the held to
maturity portfolio.

       Harleysville Group has not held or issued derivative financial
instruments.


 5 - REINSURANCE

       In the ordinary course of business, Harleysville Group cedes
insurance to, and assumes insurance from, insurers to  limit its
maximum loss exposure through diversification of its risks.  See
Note 3(a) for discussion of reinsurance with Mutual.  Reinsurance
contracts do not relieve Harleysville Group of primary liability as
the originating insurer.  After excluding reinsurance transactions
with Mutual under the pooling arrangement,  the effect of
Harleysville Group's share of other reinsurance on premiums written
and earned is as follows:

       Harleysville Group recognized favorable development in the
provision for insured events of prior years of $29,728,000,
$34,999,000 and $10,887,000 in 1997, 1996 and 1995, respectively. 
The favorable development in 1997 and 1996 primarily related to
lower than expected claim severity in the workers compensation and
automobile lines of business.  The 1995 favorable development
primarily related to lower than expected claim severity in workers
compensation.

       In establishing the liability for unpaid losses and loss
settlement expenses, management considers facts currently known and
the current state of the law and coverage litigation.  Liabilities
are recognized for known losses (including the cost of related
litigation) when sufficient information has been developed to
indicate the involvement of a specific insurance policy, and

management can reasonably estimate its liability.  In addition,
liabilities have been established to cover additional exposures on
both known and unasserted losses.  Estimates of the liabilities are
reviewed and updated continually.

       The property and casualty insurance industry has received
significant publicity about environmental-related losses from
exposures insured many years ago.  Since the intercompany pooling
agreement pertains to insurance business written or earned on or
after January 1, 1986, Harleysville Group has not incurred
significant environmental-related losses.

       Debt is as follows:

     The fair value of the notes was $75,517,000 and $73,267,000 at
December 31, 1997 and 1996, respectively, based on quoted market
prices for the same or similar debt.  The carrying value of the
remaining debt approximates fair value.

       The EDC obligation is secured by Lake States' building. 
Interest is payable semiannually at a variable rate (3.85% at
December 31, 1997) equal to the market interest rate that would
allow the bonds to be remarketed at par value.  The bonds are
subject to redemption prior to maturity in 2006 at levels dependent
upon the occurrence of certain events.

 9 - SHAREHOLDERS' EQUITY

       A source of cash for the payment of dividends is dividends
from subsidiaries.  Harleysville Group Inc.'s insurance
subsidiaries are required by law to maintain certain minimum
surplus on a statutory basis, and are subject to risk-based capital
requirements and to regulations under which payment of a dividend
from statutory surplus is restricted and may require prior approval
of regulatory authorities.  Applying the current regulatory
restrictions as of December 31, 1997, $24,061,000 would be
available for distribution to Harleysville Group Inc. without prior
approval until September 30, 1998, after which $57,808,000 would be
available for distribution to Harleysville Group Inc. without prior
approval.

       The following table contains selected information for
Harleysville Group Inc.'s property and casualty insurance
subsidiaries, as determined in accordance with prescribed statutory

       A valuation allowance is required to be established for any
portion of the deferred tax asset that management believes will not
be realized.  In the opinion of management, it is more likely than
not that the benefit of the deferred tax asset will be realized
and, therefore, no such valuation allowance has been established.

11 - INCENTIVE PLANS

       Harleysville Group applies APB Opinion No. 25 in accounting
for its stock-based compensation plans.  Accordingly, no
compensation cost has been recognized for its fixed stock option
plans and certain of its stock purchase plans.  Had compensation
cost for these stock-based compensation plans been determined under
SFAS No. 123, Harleysville Group's net income and earnings per
share would have been reduced to the pro forma amounts indicated
below:
                                    1997          1996           1995

       The per share weighted-average fair value of options granted
during 1997, 1996 and 1995 was $5.36, $3.83 and $3.95,
respectively.  The fair value of each option grant is estimated on
the date of grant using the Black-Scholes option-pricing model with
the following weighted-average assumptions used for grants in 1997,
1996 and 1995, respectively:  dividend yield of 2.34%, 2.87% and
2.72%; expected volatility of 26.06%, 26.13% and 29.69%; risk-free
interest rate of 6.65%, 6.4% and 6.25%; and an expected life of
5.75 years for 1997 and 6.5 years for 1996 and 1995.

Fixed Stock Option Plans
- ------------------------

       Harleysville Group has an Equity Incentive Plan (EIP) for key
employees.  Awards may be made in the form of stock options, stock
appreciation rights (SARs), restricted stock or any combination of
the above.  The EIP was amended in 1997 and limited future awards
to an aggregate of 4,260,946 shares of Harleysville Group Inc.'s
common stock.  The plan provides that stock options may become
exercisable from six months to 10 years from the date of grant with
an option price not less than fair market value on the date of
grant.  The options normally vest 50% at the end of one year and
50% at the end of two years from the date of grant.  SARs have not
been material.

       The income tax benefit related to the difference between the
market price at the date of exercise and the option price for non-
qualified stock options was credited to additional paid-in capital.

       The Harleysville Group Inc. 1995 Directors' Stock Option
Program provides for the granting of options to eligible directors
to purchase a maximum of 130,000 shares of common stock.  Options
are granted at exercise prices equal to fair market value on the
date of grant.  The options vest and become exercisable as follows: 
20% six months after the date of grant and thereafter 20% per year
of active service.  The options have a term of 10 years.

       Harleysville Group maintains stock option plans for
substantially all employees and certain designated agents.  The
plans provide for the granting of options to purchase a maximum of
850,000 shares of common stock.  The plans provide that the options
become exercisable from three to 10 years from the date of grant

                                   Independent Auditors' Report


The Board of Directors
Harleysville Group Inc.:

We have audited the accompanying consolidated balance sheets of
Harleysville Group as of December 31, 1997 and 1996, and the
related consolidated statements of income, shareholders' equity,
and cash flows for each of the years in the three-year period ended
December 31, 1997.  These consolidated financial statements are the
responsibility of the Company's management.  Our responsibility is
to express an opinion on these financial statements based on our
audits.

We conducted our audits in accordance with generally accepted
auditing standards.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement.  An audit
includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements.  An audit also
includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall
financial statement presentation.  We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to
above present fairly, in all material respects, the financial
position of Harleysville Group as of December 31, 1997 and 1996,
and the results of their operations and their cash flows for each
of the years in the three-year period ended December 31, 1997, in
conformity with generally accepted accounting principles.

EXHIBIT 13(D)


MARKET FOR COMMON STOCK AND RELATED SECURITY HOLDER MATTERS

       The stock of Harleysville Group Inc. is quoted on the NASDAQ
National Market System, and assigned the symbol HGIC.  At the close
of business on March 3, 1998, the approximate number of holders of
record of Harleysville Group Inc.'s common stock was 2,766
(counting all shares held in nominee registration as one
shareholder).

       The payment of dividends is subject to the discretion of
Harleysville Group Inc.'s Board of Directors which each quarter
considers, among other factors, Harleysville Group's operating
results, overall financial condition, capital requirements and
general business conditions.  The present quarterly dividend of 
$0.115 per share paid in each of the third and fourth quarters of
1997 is expected to continue during 1998.  As a holding company,
one of Harleysville Group Inc.'s sources of cash with which to pay
dividends is dividends from its subsidiaries.  Harleysville Group
Inc.'s insurance company subsidiaries are subject to state laws
that restrict their ability to pay dividends.  See Note 9 of the
Notes to Consolidated Financial Statements.

       The following table sets forth the amount of cash dividends
declared per share, and the high and low bid quotations as reported
by NASDAQ for Harleysville Group Inc.'s common stock for each
quarter during the past two years.

                  EMPLOYEE STOCK PURCHASE PLAN

                  NOTES TO FINANCIAL STATEMENTS


1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accounts of the plan are maintained on the accrual basis. 
The receivable from affiliate represents the biweekly contributions
from employees which are made in the form of regular payroll
deductions and are recorded by the plan after each biweekly pay
period.


2.   DESCRIPTION OF THE PLAN

     All regular full-time employees and regular part-time
employees who work at least twenty hours a week are eligible to
participate in the plan.

     Eligible employees must authorize a payroll deduction equal to
no more than 15 percent of their base pay during the enrollment
periods to participate in the plan.  The enrollment periods are the
1st through 14th day of January and July of each plan year.  Once
enrolled, an eligible employee will continue to participate in the
plan for each succeeding subscription period until the employee
terminates participation or ceases to be an eligible employee.

     Each subscription period will run from January 15 through July
14 or from July 15 through January 14.  At the close of each pay
period, the amount to be deducted from each participant's base pay
will be credited to such participant's plan account.  On the last
day of each subscription period, the amount credited to each
participant's plan account will be divided by the subscription
price for that subscription period and the participant's account
will be credited with the number of the whole and fractional shares
which results.  Participants may request such shares to be issued
in certificate form.

     If a participant desires to change the rate of contribution
the participant may do so effective for the next subscription
period by filing a new subscription agreement during the applicable
enrollment period.  At any time, a participant may withdraw from
the plan and receive cash for the amount deducted from the
participant's base pay during that subscription period by giving
written notice to the Company.  Separation from employment for any
reason including death, disability or retirement shall be treated
as an automatic withdrawal from the plan.

     At December 31, 1997, there were 672 participants in the plan.

                           (Continued)


3.   INVESTMENT

     The contributions credited to the participant's account are
used to purchase shares of Harleysville Group Inc. common stock at
a specified subscription price.  The subscription price for each
share of common stock shall be the lesser of 85 percent of the fair
market value of such shares on the last trading day before the
first day of the subscription period or 85 percent of the fair
market value of such share on the last day of the subscription
period.  The fair market value of a share shall be the closing
price as reported on the NASDAQ National Market System on the
applicable date.  The total number of shares to be made available
under the plan is approximately 1,000,000 shares of common stock of
the Company.


4.   TAX STATUS

     The plan is intended to qualify under the provisions of
Section 423 of the Internal Revenue Code.  No income will be
realized for federal income tax purposes by a participant upon the
purchase of shares under the plan.  Tax consequences to the Company
and to plan participants upon disposition of shares under the plan
vary depending on the length of time held and fair market value at
time of disposition.


5.   PLAN TERMINATION

     The plan will be in effect until the earlier of July 31, 2005
or the date on which plan participants have subscribed for the
total number of shares available for purchase under the plan.  At
December 31, 1997, there are approximately 689,576 shares that
remain available for issuance under the plan.  During the effective
duration of the plan, there will be twenty subscription periods.


6.   SUBSEQUENT EVENT

     On January 15, 1998, 45,384 shares of stock were  purchased at
