                       Report of Independent Accountants

We  have  audited the  consolidated  financial  statements  and
the  financial
statement  schedules  of  Minnesota   Mining  and  Manufacturing 
Company  and
subsidiaries  (the company) as listed  in Item  8 and  Item 14(a)
of this Form
10-K.   These financial statements  and financial statement 
schedules are the
responsibility  of the Company's management.  Our responsibility
is to express
an  opinion on  these financial  statements and financial 
statement schedules
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  misstatements.    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 financial statements  referred to above
present fairly, in
all material respects, the consolidated financial position of
Minnesota Mining
and Manufacturing  Company and subsidiaries as of  December 31,
1993 and 1992,
and the consolidated results of their operations and their cash
flows for each
of the three  years in the period  ended December 31, 1993 in 
conformity with
generally  accepted accounting principles.   In addition, in  our
opinion, the
financial statement schedules  referred to above, when 
considered in relation
to the basic  financial statements taken  as a whole,  present
fairly, in  all
material respects, the information required to be included
therein.

As discussed in the Notes to the Financial Statements, the
company changed the
fiscal year-end  of its  international companies  in 1992.   The 
company also
adopted  in  1992  Statements  of  Financial  Accounting 
Standards  No.  106,
"Employers' Accounting  for Postretirement Benefits Other  Than
Pensions," and
No. 109, "Accounting for Income Taxes."

Notes to Financial Statements

  Accounting Policies
  Consolidation:      All    significant   subsidiaries   are   
consolidated.
  Unconsolidated subsidiaries and affiliates are included on the
equity basis. 

  Cash and  Cash Equivalents:  Cash  and cash equivalents consist 
of cash and
  temporary investments with maturities of three months or less
when purchased.

  Other  Securities:   Other securities consist  of marketable 
securities and
  interest-bearing bank deposits with  varied maturity dates. 
These  securities
  are employed in the  company's banking, captive insurance and 
cash management
  operations.  The securities are stated at cost, which
approximates fair value.

  Inventories:  Inventories are stated  at lower of cost or
market,  with cost
generally determined on a first-in, first-out basis.

  Investments:  Investments  primarily include assets  from
captive  insurance
and  banking   operations  and  from  venture  capital  
investments.    These
investments are stated at cost, which approximates fair value.

  Other Assets:   Other assets include  goodwill, patents, other 
intangibles,
deferred taxes and  other noncurrent  assets.  Other  assets are 
periodically
reviewed  for  impairment  to  ensure  that  they  are 
appropriately  valued.
Goodwill is generally amortized on a straight-line basis over 10
years.  Other
intangible items are amortized  on a straight-line basis over 
their estimated
economic lives.

  Deferred  Income Taxes:   Deferred  income taxes  arise from 
differences in
basis for tax and financial-reporting purposes.

  Revenue  Recognition:   Revenue  is recognized  upon  shipment
of  goods  to
customers and upon performance of services.

  Depreciation:   Depreciation of property,  plant and equipment 
is generally
computed on  a straight-line basis  over the  estimated useful
lives  of these
assets.

  Research and Development:   Research  and development costs 
are charged  to
operations as incurred and totaled $1.030  billion in 1993,
$1.007 billion  in
1992 and $914 million in 1991.

  Foreign Currency Translation:  Local currencies are generally
considered the
functional  currencies outside  the United  States, except  in
countries  with
highly inflationary economies.  Assets and liabilities are
translated at year-
end exchange rates for  operations in local currency
environments.  Income and
expense  items are translated at  average rates of  exchange
prevailing during
the   year.    Translation  adjustments   are  recorded  as   a 
component  of
stockholders' equity.
   For  operations in  countries with  highly inflationary 
economies, certain
financial  statement amounts are translated at historical
exchange rates, with
all other assets and liabilities translated at year-end exchange
rates.  These
translation  adjustments are  reflected in  the results  of
operations.   They
decreased  net income  by $12  million in  1993, increased  net
income  by $10
million in 1992 and decreased net income by $6 million in 1991.

  Accounting Changes
Effective  January  1,  1992,  3M's  international  companies 
changed   their
reporting  period from  a fiscal  year ending  October 31  to a 
calendar year
ending  December 31.  The change was  made to aid worldwide
business planning,
increase efficiency and reflect  the global nature of the 
company's business.
The international companies' results  of operations for the
period  November 1
to  December 31, 1991, are shown in  the 1992 Consolidated
Statement of Income
as  a cumulative  effect  of an  accounting change.    The cash 
flows  of the
international  companies for the 14-month period November 1,
1991, to December
31, 1992, are reflected in the 1992 Consolidated Statement of
Cash Flows.
  Effective  January  1,  1992,  the company  adopted  Statement 
of Financial
Accounting Standards (SFAS) No. 106, "Employers' Accounting for
Postretirement
Benefits  Other Than  Pensions."   This statement  requires that 
the  cost of
providing postretirement  benefits  be  accrued  over  an 
employee's  service
period.  In implementing this standard, the company was required
to accrue the
unfunded  obligation.  The company had accrued  and funded -
under a different
actuarial methodology - a substantial amount of these benefits
since 1977.  In
implementing this  standard,  the company  elected  to record 
the  transition
obligation using the immediate recognition option.
  Also   effective  January  1,  1992,  the  company  adopted 
SFAS  No.  109,
"Accounting for Income Taxes."  This statement requires an asset
and liability
approach for financial  accounting and reporting of income 
taxes.  Under this
approach, deferred  taxes are recognized  for the  estimated
taxes  ultimately
payable or recoverable based on enacted tax law.  Changes in
enacted tax rates
will be reflected in the tax provision as they occur.
  Adoption of these accounting changes, in aggregate, did  not
have a material
impact on 1992 results of operations.  
  The  table below shows the components of the cumulative effect
of accounting
changes.

  Legal Settlement and Special Charges
In  December 1992,  Johnson  &  Johnson  agreed  to pay  3M  $129 
million  in
settlement of  a patent lawsuit involving 3M orthopedic casting
materials.  3M
received payment in January 1993.

In 1992,  3M  recorded $115  million of  special charges 
designed to  enhance
competitiveness and productivity.   About 75 percent of these 
charges related
to asset write-downs, including rationalization of manufacturing
operations.

  Long-Term Debt
 Employee Stock Ownership Plan:  In 1989,  the company
established an Employee
Stock Ownership Plan  (ESOP).  The  ESOP borrowed $548  million. 
Because  the
company  has guaranteed  repayment  of the  ESOP  debt, the  debt
and  related
unearned compensation are recorded on the Consolidated Balance
Sheet.
 Medium-Term Notes:   3M maintains a  shelf registration  with
the  Securities
and Exchange Commission that provides the means to offer
medium-term notes not
to exceed $601 million.  As  of December 31, 1993, $502 million 
was available
for future  financial  needs.   The company  entered into 
interest rate  swap
agreements  to achieve  variable interest  rates below  U.S.
commercial  paper
rates  for  notes  outstanding.    The  effective  rate  of 
these  agreements
approximated 2.5 percent at year-end 1993.
 Other  Borrowings:   These  are primarily  borrowings  of 3M's 
international
companies and municipal  bond issues  in the  United States.  
Interest  rates
range mainly from 2.3 to 11.0 percent.

_____________

 Maturities of long-term  debt for the next  five years are as 
follows: 1994,
$79  million; 1995,  $168 million; 1996,  $44 million; 1997,  $41
million; and
1998, $159 million.
 Interest  payments included  in  the  Consolidated  Statement of 
Cash  Flows
totaled $53  million in 1993,  $88 million in 1992  and $118
million  in 1991.
For the calendar year 1992, interest payments were $79 million.
 The  company  estimates  that  the  fair  value  of  long-term 
debt  is  not
materially different than the carrying amount of this debt.

  Other Financial Instruments
The company  has entered  into interest  rate and currency 
swaps, as  well as
forward interest rate  agreements, with face amounts of  $605
million and $308
million, respectively,  as of December 31,  1993, and 1992.   The
company uses

                                      27
<PAGE>

these  instruments to manage risk from interest rate and currency
fluctuations
and to  lower its  cost of  borrowing.   The unrealized  gains
and  losses are
deferred until the  underlying transactions are realized.  As  of
December 31,
1993, the unrealized gains and losses were not material.
 The company also had foreign exchange forward and option
contracts with  face
amounts  of $704 million and $785 million, respectively, at
December 31, 1993,
and 1992.   The  company uses these  financial instruments
primarily  to hedge
transactions  denominated in  foreign currencies,  thereby
reducing  risk from
exchange rate  fluctuations in the regular course of its global
business.  The
net unrealized  gain on  these  contracts as  of December  31, 
1993, was  not
material.

 Net deferred tax assets totaled $439 million ($293 million
current) and net
 deferred tax liabilities totaled $98 million ($6 million
current) at year-end
 1993.  The major components of deferred taxes include benefit
costs not
 currently deductible of $336 million and accelerated
depreciation for tax
 purposes of $362 million.
 Income tax payments included in the Consolidated Statement of
Cash Flows
 totaled $802 million in 1993, $743 million in 1992 and $867
million in 1991.
 For calendar year 1992, income tax payments were $714 million.
 At December 31, 1993, there were approximately $2.850 billion of
retained
 earnings attributable to our international companies that are
considered to
 be permanently invested.  No provision has been made for taxes
that might be
 payable if these earnings were remitted to the United States. 
It is not
 practical to determine the amount of incremental tax that might
arise should
 these earnings be remitted.

U.S. employees and many employees outside the United States. 
Pension benefits
are based principally on an employee's years of  service and
compensation near
retirement.    Plan  assets  are  invested  in  common   stocks, 
fixed-income
securities, real estate and other investments.
 The company's  funding  policy  is to  deposit  with an 
independent  trustee
amounts at least equal to those  required by law.  A trust fund 
is maintained
to provide pension benefits to plan participants  and their
beneficiaries.  In
addition,  a number  of  plans  are  maintained  by  deposits 
with  insurance
companies.
  The charge to income  relating to these plans was $203 million
in 1993, $178
million in 1992 and $133 million in 1991.

  Other Postretirement Benefits
The company provides health care and life insurance benefits for
substantially
all  of its  U.S. employees  who reach  retirement age  while
employed  by the
company.   The  company has set  aside funds  with an 
independent trustee for
these postretirement  benefits and makes  periodic contributions
to  the plan.
The assets  held by the trustee are invested in common stocks and
fixed-income
securities.   Employees outside the  United States are  covered
principally by
government-sponsored plans  and the cost  of company-provided
plans  for these
employees is not material.
 The table below sets forth the components of the net  periodic
postretirement
benefit cost and  a reconciliation of the funded  status of the
postretirement
benefit plan for U.S. employees.

 The  accumulated postretirement  benefit obligation and  related
benefit cost
are determined through the application of relevant actuarial
assumptions.  The
company anticipates its  health care cost trend rate to  slow
from 7.5 percent
in  1994 to 5.0  percent in 2003,  after which the  trend rate is 
expected to
stabilize.   The  effect of  a one  percentage point  increase in 
the assumed
health care  cost trend rate for  each future year would 
increase the benefit
obligation by  $57 million and the current year benefit expense
by $4 million.
Other  actuarial assumptions include an  expected long-term rate 
of return on
plan assets of 9.0 percent (before taxes applicable to a portion
of the return
on plan assets), and a discount rate of 7.25 percent.
 The charge to  income relating to  these plans was $54  million
in 1993,  $50
million in 1992 and $51 million in 1991.

  Other Postemployment Benefits
 In 1992, the Financial  Accounting Standards Board issued
Statement  No. 112,
"Employers' Accounting for Postemployment  Benefits." 
Postemployment benefits
include,  but  are  not limited  to,  disability,  severance  and
health  care
benefits.   3M will  adopt this standard in  the first quarter 
of 1994.  This
adoption will have a diminimus effect on the company's results of
operations.

  Employee Stock Ownership Plan
The   company  maintains   an  Employee   Stock  Ownership  Plan  
(ESOP)  for
substantially all full-time U.S. employees.  This plan was
established in 1989
as  a  cost-effective  way  of  funding certain  employee 
retirement  savings
benefits, including  the company's  matching  contributions under 
its  401(k)
employee savings plan.  The  ESOP borrowed $548 million and used 
the proceeds
to purchase 7.7  million shares of the company's common stock,
previously held
in  treasury.  The  debt is being serviced  by dividends on 
stock held by the
ESOP and by  company contributions.   These  contributions are 
reported as  a
benefit expense.

  Employee Savings Plan
The company  sponsors an  employee savings  plan under  Section
401(k) of  the
Internal  Revenue Code.   This  plan covers  substantially all 
full-time U.S.
employees.  The company matches  employee contributions of up to
6  percent of
compensation at rates  ranging from 35  to 85 percent, depending 
upon company
performance.   Amounts  charged against  income were $29  million
in  1993 and
1992, and $28 million in 1991.

  General Employees' Stock Purchase Plan
Participants in the General Employees' Stock Purchase Plan are
granted options
at 85 percent  of market value at  the date of grant.   At
December 31,  1993,
there were  23,216 participants in the plan, with 58,058
employees eligible to
participate.  Options must be exercised within 27 months from
date of grant.
