STOCKHOLDERS".   The  shares  of  Common Stock offered  hereby  by  the  Selling
Stockholders  consist  of  731,300 shares of Common Stock currently  issued  and
outstanding.  This  presentation  is not intended,  and  should  in  no  way  be
construed,  to  constitute a prediction as to the future  market  price  of  the
Common  Stock.   See "RISK FACTORS - Dilutive Effect of Issuance  of  Additional
Shares on Current Shareholders" and  "SELLING STOCKHOLDERS".

      The  Selling  Stockholders will offer their Common  Stock  through  or  to

or  in other transactions negotiated by the Selling Stockholders.  Any such sale
of  Common  Stock by Selling Stockholders must be accompanied by, or follow  the
delivery  of, a prospectus filed with a current registration statement  relating
to  the Common Stock being offered, unless a Selling Stockholder elects to  rely
on  Rule  144  or  another  exemption  from  the  registration  requirements  in
connection  with  a  particular transaction.  The Selling Stockholders  and  any
broker, dealer, or agent that participates with the Selling Stockholders in  the
sale  of  Common Stock  offered hereby may be deemed "underwriters"  within  the
meaning  of the Securities Act of 1933, as amended ( the "Securities Act"),  and
any commission or discounts received by them and any profit on the resale of the
Common  Stock  purchased  by them may be deemed to be  underwriting  commissions
under   the   Securities  Act.  (See  "SELLING  STOCKHOLDERS"   and   "PLAN   OF
DISTRIBUTION").

for legal, accounting, printing, and other costs.  Any separate costs of Selling
Stockholders will be borne by them.  Commissions or discounts paid in connection
with  the  sale of securities by the Selling Stockholders will be determined  by

securities  are  to  be  sold  and  may vary depending  on  the  broker-dealers'
commission or mark up schedule, the size of the transaction, and other  factors.

THE COMPANY
Earth  Sciences,  Inc. (the "Company") is a diversified mineral exploration  and
development  company specializing in chemical processing, air pollution  control
and  mineral exploration.  Production of purified phosphate products in  Calgary
commenced in June 1997.  The Company was incorporated under the name of Colorado
Central  Mines,  Inc. in Colorado in 1957.  Current activities  of  the  Company
include  (1) the operation of its recently modified solvent extraction  facility
in Calgary, Alberta for production of purified phosphate products; (2) continued
exploration activities for gold and diamond resources in Venezuela (3) flue  gas
conditioning  technology for coal-fired boilers and other applications  provided
through ADA Environmental Solutions LLC ("ADA"), a wholly-owned subsidiary,  and
(4)  maintenance of its position in several mineral resources and  prospects  in
the Western US.

The Company's solvent extraction facility in Calgary, Alberta, recovered uranium
from  phosphoric acid during the period from 1983 through 1987.   Uranium  oxide
production was suspended in the fall of 1987 when the adjacent fertilizer  plant
from  which  the  facility  received its feed stock suspended  operations.   The
contract  under  which  the  uranium was sold was  modified  in  1990  to  allow
unrestricted  alternative use of the facility. Revamp of the facility  to  allow
production  of  purified phosphate products was completed in 1997.  The  Calgary
facility  is routinely producing technical grade phosphoric acid and  steps  are
being evaluated for production of  food grade product later in 1998.

RECENT DEVELOPMENTS

Acquisition of ADA Environmental Solutions LLC
In   May  1998,  the  Company  acquired  the  remaining  49%  interest  in   ADA
Environmental Solutions LLC through the issuance of approximately  1,715,000  of
its  common  stock  a portion of which shares are offered for  sale  under  this
prospectus. ESCI's initial 51% interest was purchased in 1997 by payments to ADA
totaling  $2,500,000.  At  that time ESCI obtained the  option  to  acquire  the
remaining 49%. The Company believes ADA can capture a significant portion of the
utility   and  industrial  flue  gas  conditioning  market  with  its   nontoxic
conditioner,  which  offers both technical and economical  advantages  over  the
hazardous chemicals currently being used. ESCI's Calgary plant will provide  ADA
with  purified  phosphoric  acid  (PPA), the main  chemical  ingredient  in  the
process.

Exploration of  Diamond Concession
In  January  1998, the Company signed a letter agreement with CODSA 14  S.A.  to
acquire  exclusive rights to explore and mine it's diamond concession.   Located
in  southeastern Venezuela near the Brazil border, the concession  covers  6,177
acres  (2,500 hectares). The Company has made payments of cash and stock  valued
at  a  total  of  $50,000  during  the 6 month exploration  period.  Exploration
performed has indicated the lack of sufficient diamond bearing alluvial material
on  the  concession to support mechanical mining operations.  The  Company  gave
notice  to  terminate  the agreement effective July 21,  1998.  The  Company  is
evaluating other potential concessions in the area.

The  principal executive offices of the Company are located at 910 12th  Street,
Golden, Colorado  80401, and its telephone number is (303) 279-7641.

FORWARD-LOOKING STATEMENTS

In  addition  to  historical  information, this  Prospectus  and  the  documents
incorporated  herein  by  reference  contain  forward-looking  statements.   The
forward-looking  statements contained herein are subject to  certain  risks  and
uncertainties that could cause actual results to differ materially from those in
the  forward-looking  statements.  Factors that might cause  such  a  difference
include,  but are not limited to, those discussed in the section entitled  "RISK
FACTORS"  set forth below.  Investors are cautioned not to place undue  reliance
on these forward-looking statements, which reflect management's analysis only as
of  the  date  of  such  statements.  The Company undertakes  no  obligation  to
publicly   revise  these  forward-looking  statements  to  reflect   events   or
circumstances that arise after the date of such statements.

RISK FACTORS
An  investment in the Shares is speculative and involves a high degree of  risk.
In  analyzing  the  offering,  prospective investors  should  read  this  entire
Prospectus  and the information incorporated herein by reference, and  carefully
consider,  among  others, the following risk factors in addition  to  the  other
information set forth elsewhere in this Prospectus.

Specifics Risks Related to the Company
No  Dividends.  The Company has paid no cash dividends on its Common  Stock  and
has no present intention of paying cash dividends in the foreseeable future.  It
is  the  present  policy  of the Board of Directors to retain  all  earnings  to
provide for the growth of the Company.  Payments of cash dividends in the future
will   depend,   among  other  things,  upon  the  Company's  future   earnings,
requirements for capital improvements, the operating and financial conditions of
the Company and other factors deemed relevant by the Board of Directors.

Lack  of  Profitability.  While the Company reported net income in fiscal  1995,
the  Company's operating history has resulted in losses from operations  in  the
fiscal  years ending December 31, 1988 through 1994, in 1996, and  1997.   While
certain  of  the  Company's operations may be profitable during a  given  fiscal
year, the Company's operations as a whole may be unprofitable due to exploration
and  development  costs  on  properties from which no  revenue  is  derived,  to
continuing  corporate general and administrative costs and to  interest  expense
associated with long term debt.

                                        6
<PAGE>

Dilutive  Effect of Issuance of Additional Shares on Current Shareholders.   The
Board  of  Directors  has  the authority to authorize  the  offer  and  sale  of
additional  securities  without the vote of or notice to existing  shareholders,
and  it  is  likely that additional securities will be issued to provide  future
financing  or  in  connection  with acquisitions.  The  issuance  of  additional
securities  could dilute the percentage interests and per share  book  value  of
existing shareholders, including persons purchasing securities in this offering.

Volatility  of  Price  for Common Stock.  The market price  for  shares  of  the
Company's Common Stock may be highly volatile depending on news announcements or
changes  in  general market conditions.  In recent years the  stock  market  has
experienced extreme price and volume fluctuations.

Risks Related to the Exploration and Development of Minerals
Nature  of  Mineral  Exploration and Development; No Proven Commercially  Viable
Reserves  Yet  Discovered on the Company's Mineral Properties.  Exploration  for
minerals  is  highly speculative and may involve greater risks than  many  other
businesses.   Many  exploration  programs,  including  those  which  have   been
conducted  by the Company, do not result and have not resulted in the  discovery
of  mineralization and any mineralization discovered may not  be  of  sufficient
quantity  or  quality to be profitably mined.  The Company's mineral exploration
and development activities are subject to all of the operating hazards and risks
normally incident to such activities, such as encountering unusual or unexpected
formations, environmental pollution, personal injury and flooding.  All of these
factors  may  result in losses in relation to the amounts spent  which  are  not
recoverable.   With  the  exception of the San  Luis  gold  mine  (where  mining
operations have been terminated as described below in "Termination of Mining  at
the  San  Luis  Gold  Mine"),  no commercially viable  reserves  have  yet  been
discovered on the Company's mineral properties.

Competition  and Scarcity of Mineral Lands.  Many companies and individuals  are
engaged  in  mineral  exploration and development, including large,  established
mining companies with substantial capabilities and long earnings records.  There
is  a  limited  amount of desirable mineral lands available for  claim  staking,
lease  or  other  acquisition in the United States ("US"), Venezuela  and  other
areas  where  the  Company contemplates conducting exploration activities.   The
Company  may  be  at a competitive disadvantage in acquiring mineral  properties
since  it must compete with these individuals and companies, many of which  have
greater financial resources and larger technical staffs than the Company.   From
time  to  time, specific properties or areas which would otherwise be attractive
to  the  Company  for exploration or acquisition are unavailable  due  to  their
previous acquisition by other companies.

Fluctuation in the Price of Minerals.  The market price of minerals is extremely
volatile  and  beyond  the control of the Company.  Gold  prices  are  generally
influenced  by  basic  supply/demand  fundamentals.   The  market  dynamics   of
supply/demand can be heavily influenced by economic policy, i.e., central  banks
sales/purchases,  political  unrest,  conflicts  between  nations,  and  general
perceptions  about inflation.  Fluctuating metal prices may have  a  significant
impact  on  the  Company's  results  of  operations  and  operating  cash  flow.
Furthermore,  if the price of a mineral should drop dramatically, the  value  of
the  Company's properties which are being explored or developed for that mineral
could  also drop dramatically, and the Company might not be able to recover  its
investment in those properties.  The decision to put a mine into production, and
the commitment of the funds necessary for that purpose, must be made long before
the  first  revenues  from production will be received.  During  the  last  five
years,  the average annual market price of gold has fluctuated between $280  per
ounce  and  $384  per ounce.  Price fluctuations between the time  that  such  a
decision  is  made and the commencement of production can change completely  the
economics  of  the  mine.   Although it is possible  to  protect  against  price
fluctuations  by  hedging in certain circumstances, the  volatility  of  mineral
prices  represents a substantial risk in the mining industry generally which  no
amount  of  planning or technical expertise can eliminate.  The Company  is  not
involved in, nor does it expect to enter into any hedging activities


                                        7
<PAGE>
Environmental Controls.  Compliance with environmental quality requirements  and
reclamation  laws imposed by federal, state, provincial, and local  governmental
authorities  may necessitate significant capital outlays, may materially  affect
the  economics of a given property, or may cause material changes or  delays  in
the  Company's intended activities.  The Secretary of the Interior has  directed
the BLM to propose amendments to surface management regulations that impose more
stringent  reclamation  and  environmental  protection  requirements  on  mining
operations.  The extent of the changes, if any, which may be made by the BLM  is
not  presently  known, and the potential impact on the Company as  a  result  of
future   regulatory  action  is  difficult  to  predict.    New   or   different
environmental standards imposed by any governmental authority in the future  may
adversely affect the Company's activities.

Uncertainty of Title.  Several of the Company's mining properties which  are  in
the  United States are unpatented mining claims to which the Company,  or  those
under  which  the Company holds its rights, has only possessory title.   Because
title  to unpatented mining claims is subject to inherent uncertainties,  it  is
difficult  to  determine  conclusively  ownership  of  such  claims.   Since   a
substantial  portion of all mineral exploration, development and mining  in  the
United  States  now  occurs  on unpatented mining claims,  this  uncertainty  is
inherent  in the mining industry.  In addition, in order to retain title  to  an
unpatented  mining  claim, a claim holder must have met annual  assessment  work
requirements  ($100 per claim) through September 1, 1992 and must have  complied
with  stringent  state  and  federal regulations pertaining  to  the  filing  of
assessment  work affidavits.  Moreover, after September 1, 1992,  the  right  to
locate  or maintain a claim generally is conditional upon payment to the  United
States  of  a  rental  fee of $100 per claim per year for each  assessment  year
instead of performing assessment work.  State law may, in some instances,  still
require performance of assessment work.

The  present  status  of  the Company's properties as unpatented  mining  claims
located  on public lands of the U.S. allows the claimant the exclusive right  to
mine  and  remove  valuable  minerals, such as  precious  and  base  metals  and
industrial  minerals, found therein, and also to use the  surface  of  the  land
solely  for purposes related to mining and processing the mineral-bearing  ores.
However, legal ownership of the land remains with the U.S.  Accordingly, with an
unpatented claim, the U.S. retains many of the incidents of ownership  of  land,
the  U.S. regulates use of the surface, and the Company remains at risk that the
claims may be forfeited either to the U.S. or to rival private claimants due  to
failure to comply with statutory requirements as to locations and maintenance of
the claims.  If there exists a valuable deposit of locatable minerals (which  is
the  requirement for the unpatented claim to be valid in the first  place),  and
provided  certain  levels of work and improvements have  been  performed  on  an
unpatented  mining  claim, the Mining Law of 1872 authorizes claimants  to  then
seek  to  purchase  the full title to the claim, thereby causing  the  claim  to
become  the  private property of the claimant.  Such full ownership expands  the
claimant's  permissible uses of the property (to any use authorized for  private
property)  and  eliminates  the need to comply with  maintenance  and  reporting
requirements  necessary to protect rights in an unpatented  claim.   At  present
there is a statutory moratorium in effect prohibiting the Department of Interior
from  accepting  and processing new applications for purchase of  fee  title  to
mining  claims.  The moratorium is likely to continue indefinitely but does  not
affect  the ability to hold and develop valuable deposits by means of unpatented
mining claims.

Proposed  Legislation  Affecting  the Mining Industry.   For  the  last  several
Congressional  sessions,  bills  have been repeatedly  introduced  in  the  U.S.
Congress  which would supplant or radically alter the provisions of  the  Mining
Law  of 1872.  As of July 31, 1998, no such bills have passed, although a number
of  differing and sometimes conflicting bills are now pending.  If enacted, such
legislation  could substantially increase the cost of holding unpatented  mining
claims and could impair the ability of companies to develop mineral resources on
unpatented mining claims.  Under the terms of certain proposed legislation,  the
ability  of  companies to obtain a patent on unpatented mining claims  would  be
nullified  or substantially impaired.  Moreover, certain forms of such  proposed
legislation  contain  provisions for the payment of  royalties  to  the  federal
government  in respect of production from unpatented mining claims, which  could
adversely  affect the potential for development of such claims and the economics
of  operating existing mines on federal unpatented mining claims.  The Company's
financial performance could therefore be affected adversely by passage  of  such
legislation.   It  is  impossible to predict at this point what  any  legislated
royalties  might  be,  but  a  potential three to four  percent  gross  royalty,
assuming  a gold price of $300 per ounce, would have an approximated $9  to  $12
per ounce impact on the Company's costs of any production from unpatented mining
claims.

                                        8
<PAGE>

Uncertainty  of  Funding for Exploration.  The Company has funded  much  of  its
exploration and acquisition activities through joint venture arrangements, which
minimize the cost of such activities to the Company and allow it to explore  and
acquire  a  greater  number of properties than it would  otherwise  be  able  to
explore  or  acquire on its own.  The Company has also funded a portion  of  its
exploration  activities  without  joint  venture  participation,  resulting   in
increased  costs to the Company.  The Company has been successful, to  date,  in
raising  such  funds  for its exploration activities.  Additional  funding  from
existing  partners  or  third  parties, however, may  be  necessary  to  conduct
detailed  and  thorough evaluations of, and to develop certain properties.   The
Company's ability to obtain this financing will depend upon, among other things,
the price of gold and the industry's perception of its future price.  Therefore,
availability  of  funding  is  dependent largely upon  factors  outside  of  the
Company's  control, and cannot be accurately predicted.  The  Company  does  not
know  from what sources it will derive any required funding.  If the Company  is
not  able to raise additional funds (as to which there can be no assurance),  it
will not be able to fund certain exploration activities on its own.

Uncertainty  of Development and Operating Property Economics and Ore  Grades  at
Development  Properties.  Decisions as to whether any of the mineral development
properties  which the Company now holds or which it may acquire  in  the  future
contain  commercially  minable  deposits, and  whether  such  properties  should
therefore  be  sold  or  brought into production, depend  upon  the  results  of
exploration programs and/or feasibility analyses and the recommendations of duly
qualified  engineers  or geologists.  Such decisions involve  consideration  and
evaluation  of several significant factors, including, but not limited  to,  the
(a)  costs  of  bringing a property into production, including  exploration  and
development work, preparation of production feasibility studies and construction
of  production facilities, (b) availability and costs of financing, (c)  ongoing
costs  of production, (d) market prices for the mineral to be produced, and  (e)
the  amount  and grades of reserves or mineralized material.  There  can  be  no
assurance  that  any of the development properties now held by the  Company,  or
which  may  be acquired by the Company, contains a commercially minable  mineral
deposit,  and  therefore  no assurance that the Company  will  ever  generate  a
positive cash flow from the sale of or production operations on such properties.
In  addition,  once a property is sold with a retained royalty  or  placed  into
production, risks still exist that the amount and grade of its reserves will not
actually  be  as predicted.  To the extent that lower amounts and/or  grades  of
reserves  are  experienced, costs per unit produced  and  profitability  can  be
adversely affected.  Depending upon the extent of such an effect in any  of  the
Company's  properties, the Company could incur a writedown on its investment  in
any such property.

Termination  of Mining at the San Luis Gold Mine.  Royalty income from  the  San
Luis  gold  mine has been the only significant source of income for the  Company
during  the period from 1990 through 1996.  The mine was leased to and  operated
by  Battle  Mountain  Gold Co. ("BMGC").  As reported to the  Company  by  BMGC,
mining  was completed at the end of October, 1996.  The Company's royalty income
from the property ceased shortly after that time.

Risks Related to the Production and Sale of Purified Phosphate Products and ADA

Uncertain  Commercial  Viability  of Solvent Extraction  Process.   The  solvent
extraction  process  developed by the Company for  the  production  of  purified
phosphoric acid ("PPA") has not been proven on a continuing commercial basis  at
the  Calgary plant.  Although the Company has performed numerous bench-scale and
pilot  plant  test of the process, there can be no assurances that  the  process
will yield satisfactory results when employed on a continuing commercial scale.

Limited Experience in Marketing Industrial Chemicals and Lack of Long-term Sales
Contracts.  The growth and profitability of operations at the Company's  solvent
extraction  facility in Calgary will be dependent upon, among other things,  the
sale of purified phosphate products to chemical distributors and customers.  The
Company  has limited experience in marketing industrial chemicals and is relying
on  consultants and others to initiate and maintain sales contacts.  PPA is  not
typically sold under long-term contracts, and the Company does not have any 
long-term  commitments to purchase its planned products.  There can be no 
assurances that the Company will be successful in its future sales efforts.

                                        9
<PAGE>

Supply  of  Raw  Materials. The growth and profitability of  operations  at  the
Company's  solvent extraction facility in Calgary will be dependent upon,  among
other things, the availability of sufficient raw materials at reasonable prices.
The  Company  has  negotiated a renewable annual supply contract  with  Farmland
Industries  ("Farmland")  and  a  supply  arrangement  with  Agrium  U.S.   Inc.
("Agrium") to supply the estimated requirement of superphosphoric acid  ("SPA").
The  contract  with  Farmland contains provisions that allow  extension  of  the
contract  in the future or termination upon a 90 day written notice.  There  can
be  no  assurances  that the Company will be able to extend  this  contract  and
supply  arrangement in the future and/or obtain sufficient quantities of SPA  at
reasonable prices.

Ability to Expand Geographically. The growth and profitability of operations  at
the  Company's  solvent extraction facility in Calgary will be  dependent  upon,
among other things, the ability to become the predominate supplier of PPA in the
geographic region surrounding Calgary and on the US West Coast, and to  sell  on
an  increasing basis to the Minneapolis/Chicago area.  There can be no assurance
that  the  Company's efforts to expand sales can be accomplished on a profitable
basis.

Competition.  The Company's purified phosphate products will be sold in  markets
that  are highly competitive.  The principal competitive factors include product
quality,  price and distribution capabilities.  There can be no assurances  that
the  Company  will  be able to compete successfully against current  and  future
competitors  based  on  these factors.  The Company will  compete  with  several
domestic  and  international producers, many of whom have substantially  greater
financial,  production, distribution and marketing resources than  the  Company.
Increased competition could result in price reductions, reduced margins and loss
of  market  share,  all  of which could have a material adverse  affect  on  the
Company's business, financial condition and results of operations.

Effect  of Potential Lack of Demand for ADA's Services.  If there is no  demand,
or  the  demand  is  less  than  projected, for  ADA's  services  for  flue  gas
conditioning,  the  Company will not recognize the synergies expected  from  its
acquisition,  because  ADA will not be able to utilize  the  Company's  purified
phosphate products.

PLAN OF DISTRIBUTION

This  Prospectus  relates to the public offer and sale by  certain  shareholders
(the "Selling Stockholders") of 731,300 shares of Common Stock currently held by
Selling Stockholders.

The  Common  Stock to be sold by the Selling Stockholders  may be sold  by  them
from   time  to  time  directly  to  purchasers.   Alternatively,  the   Selling
Stockholders may, from time to time, offer the Common Stock through  dealers  or
brokers,  who receive compensation in the form of commissions from  the  Selling
Stockholders  and/or the purchasers of the Common Stock for  whom  they  act  as
agents.  As of the date hereof, no Selling Stockholders have advised the Company
that  they  have entered into any agreement or understanding with any dealer  or
broker for the offer or sale of the Common Stock.  The Selling Stockholders  may
enter  into  such  agreements  or understandings in  the  future.   The  Selling
Stockholders  may  also  offer some or all of the Common  Stock  through  market
transactions on Nasdaq, on which the Company's Common Stock is traded.  Sales of
the Common Stock through brokers may be made by any method of trading authorized
by Nasdaq, including block trading in negotiated transactions.  Without limiting
the  foregoing, such brokers may act as dealers purchasing any  or  all  of  the
Common Stock covered by this Prospectus.  Sales of Common Stock are, in general,
expected  to  be made at the market price prevailing at the time  of  each  such
sale;  however,  prices in negotiated transactions may differ considerably.   No
Selling  Shareholder  has  advised the Company that it  anticipates  paying  any
consideration,   other  than  usual  and  customary  broker's  commissions,   in
connection with sales of the Common Stock.  The Selling Stockholders are  acting
independently  of the Company in making decisions with respect  to  the  timing,
manner and size of each sale.

DESCRIPTION OF COMMON STOCK

The  authorized  capital stock of the Company consists of 25,000,000  shares  of
Common  Stock,  $0.01  par value per share.  All of the issued  and  outstanding
stock of the Company is fully paid and nonassessable.
                                       11
<PAGE>
Holders  of Common Stock are entitled to receive dividends, when and if declared
by the Board of Directors, out of funds legally available therefore and to share
ratably  in the net assets of the Company upon liquidation.  Holders  of  Common
Stock do not have preemptive rights to subscribe for additional shares, nor  are
there  any  redemption  or sinking fund provisions associated  with  the  Common
Stock.  There are currently 21,890,144 shares of Common Stock outstanding  owned
by approximately 3,000 persons and/or entities.

Holders  of  Common  Stock are entitled to one vote per  share  on  all  matters
requiring  a  vote of the shareholders.  Since the Common Stock  does  not  have
cumulative  voting  rights in electing directors, the holders  of  more  than  a
majority  of  the outstanding shares of Common Stock voting for the election  of
directors can elect all of the directors whose terms expire that year,  if  they
so choose.

LEGAL MATTERS
Certain  legal  matters with respect to the legality of the  securities  offered
hereby  and the organization and existence of the Company have been passed  upon
for  the  Company  by  Parcel Mauro, P.C., 1801 California Street,  Suite  3600,
Denver, Colorado  80202.

Item 15.  Indemnification of Directors and Officers.

      Article  7-109  of  the Colorado Business Corporation Act  authorizes  the
indemnification of directors and officers against liability incurred  by  reason
of being a director or officer and against expenses (including attorney's fees),
judgments,  fines  and  amounts paid in settlement and  reasonably  incurred  in
connection with any action seeking to establish such liability, in the  case  of
third-party  claims, if the officer or director acted in good  faith  and  in  a
manner  he reasonably believed to be in or not opposed to the best interests  of
the  corporation,  and  in  the case of actions  by  or  in  the  right  of  the
corporation, if the officer or director acted in good faith and in a  manner  he
reasonably  believed  to  be  in or not opposed to the  best  interests  of  the
corporation and if such officer or director shall not have been adjudged  liable
to  the  corporation, unless a court otherwise determines.   Indemnification  is
also  authorized  with  respect to any criminal action or proceeding  where  the
officer  or  director also had no reasonable cause to believe  his  conduct  was
unlawful.

      The  above discussion of the Colorado Business Corporation Act is  only  a
summary and is qualified in its entirety by the full text of the foregoing.

Article VIII of the Registrant's Bylaws provides as follows:

     Each past, present and future director and officer of the corporation shall
be   indemnified  by  the  corporation  against  all  expenses,  penalties,  and
liabilities,  including attorneys' fees, reasonably incurred by or imposed  upon
him  in  connection  with  any actual or threatened  claim,  demand,  action  or
proceeding,  whether  civil or criminal, or in connection  with  any  settlement
thereof, to which he may be made a party, or in which he may become involved, by
reason  of  his  being or having been a director or officer of the  corporation,
whether  or not he is a director or officer at the time such expenses, penalties
or  liabilities are incurred, except in cases where he shall be finally adjudged
in  such  action  or  proceeding  to be liable for  willful  misconduct  in  the
performance  of  his  duties  as  such  director  or  officer.   The  right   of
indemnification herein provided shall be in addition to, and not  exclusive  of,
all other rights to which such director or officer may be entitled and the right
of  indemnification herein provided shall inure to the benefit of  the  personal
representatives of deceased directors and officers.

Item 17.  Undertakings.

     The undersigned registrant hereby undertakes:
      (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement to include any  material
information with respect to the plan of distribution not previously disclosed in
the  registration  statement or any material change to such information  in  the
registration statement.
      (2)   That,  for  the  purposes of determining  any  liability  under  the
Securities Act of 1933 (the "Act"), each such post-effective amendment shall  be
deemed  to  be  a new registration statement relating to the securities  offered
therein, and the offering of such securities at that time shall be deemed to  be
the initial bona fide offering thereof.
     (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
     (4)  That, for purposes of determining liability under the Act, each filing
of  the registrant's annual report pursuant to section 13(a) or section 15(d) of
the  Securities Exchange Act of 1934 (and where applicable, each  filing  of  an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities  Exchange  Act  of 1934) that is incorporated  by  reference  in  the
registration  statement  shall  be deemed to be  a  new  registration  statement
relating  to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
     (5)  That, insofar as indemnification for liabilities arising under the Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
Registrant  pursuant to the foregoing provisions, or otherwise,  the  Registrant
has  been  advised that in the opinion of the Securities and Exchange Commission
such  indemnification is against public policy as expressed in the Act  and  is,
therefore, unenforceable.  In the event that a claim for indemnification against
such  liabilities (other than the payment by the Registrant of expenses incurred
or  paid by a director, officer or controlling person of the Registrant  in  the
successful  defense  of  any action, suit or proceeding)  is  asserted  by  such
director, officer or controlling person in connection with the securities  being
registered, the Registrant will, unless in the opinion of its counsel the matter
has  been  settled  by controlling precedent, submit to a court  of  appropriate
jurisdiction  the question whether such indemnification by it is against  public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Registration Statement and any amendment thereto to be signed on its  behalf  by
the  undersigned,  thereunto duly authorized, in the City of  Golden,  State  of

Re:  Registration Statement on Form S-3
     Covering the Registration of 731,300
     Common Shares of Earth Sciences, Inc.

Gentlemen and Ladies:

     We have acted as counsel for Earth Sciences, Inc., a Colorado corporation
(the "Company"), in connection with the registration for sale of 731,300 shares
of the Company's Common Stock (the "Securities") in accordance with the
registration provisions of the Securities Act of 1933, as amended.

     In such capacity we have examined, among other documents, the Articles of
Incorporation and By Laws of the Company, records of corporate proceedings,  the
Registration Statement on Form S-3 filed by the Company with the Securities and
Exchange Commission on or about August  25, 1998, (as may be further amended
from time to time, the "Registration Statement"), covering the registration of
the Securities.  We have also made such other investigations and reviewed such
other documents as we have deemed necessary in order to express the opinions set
forth below.

     Based upon the foregoing and upon such further examinations as we have
deemed relevant and necessary, we are of the opinion that:

     1.   The Company is a corporation duly organized and validly existing under
the laws of the State of Colorado.

     2.   The Securities have been legally and validly authorized under the
Company's Articles of Incorporation, as amended, and duly and validly issued and
outstanding and fully paid and nonassessable shares of the Company under the
Colorado Business Corporation Act.

     We hereby consent to the use of our name beneath the caption "Legal
Matters" in the Prospectus forming a part of the Registration Statement and to
the filing of a copy of this opinion as Exhibit 5.1 thereto.

                         Very truly yours,

We  consent to the incorporation by reference of our report dated March 24, 1998
accompanying  the  financial  statements of Earth Sciences,  Inc.  to  Form  S-3
Registration  Statement of Earth Sciences, Inc. and to the use of our  name  and
the  statements with respect to us, as appearing under the heading "Experts"  in

     Re:  Registration Statement on Form S-3
          Covering the Registration of 731,300
          Common Shares of Earth Sciences, Inc.

Gentlemen and Ladies:

     On behalf of Earth Sciences, Inc., a Colorado Corporation (the "Company"),
we transmit through EDGAR, pursuant to the Securities Act of 1933, as amended
(the "1933 Act"), a registration statement on Form S-3 (the "Registration
Statement") covering 731,300 shares of Common Stock, par value $.01 per share
(the "Securities").

     The Securities are being registered in connection with sale by selling
shareholders of common shares of the Company for 731,300 shares currently held
are issued and outstanding.

     In connection with the foregoing, the following is being transmitted:

     1.   One copy of the Registration Statement; and
     2.   Copies of the exhibits listed beneath the caption "Item 16.  Exhibits"
          contained in Part II of the Registration Statement.

     The registration fee in the amount of $ 174.74 has been wired transferred
to the SEC by the Company.

     The following supplemental information is supplied in order to facilitate
timely review of the Registration Statement by the Staff:

     (1)  The Company desires that the Registration Statement become effective
as soon as practicable and, therefore, if it would be of any assistance we would
welcome the opportunity to discuss with the Staff by telephone such comments as
it may have prior to actual drafting and dispatch of its letter of comment.  In
this way we could draft in response to any comment prior to formal receipt and
thereby expedite preparation and review of any amendment and commencement of the
offering.

     (2)  The Company has reviewed the various criteria for eligibility for use
of Form S-3 and we believe that such criteria are satisfied.  Moreover, we
believe that the Registration Statement is in compliance with the applicable
Form, instructions and rules pertaining thereto and (except as otherwise
indicated herein) is complete.

     (3)  With regard to preparation of any comments by the Staff and the impact
thereof upon declaration of effectiveness, please be advised that we would be
satisfied by receipt of oral comments by the Staff for transcription by us.

     (4)  We undertake to furnish the Staff with copies of any letter of comment
or other documents received from the staff of National Association of Securities
Dealers, Inc.

     (5)  Based on the provisions of Rule 174, no legend regarding prospectus
delivery requirement has been included because the Company has been a reporting
company under the Securities Act of 1934 prior to the filing of the Registration
Statement.

     The Staff is requested to address any correspondence, comment or inquiry to
the undersigned, at the address or telephone number, as the case may be, set
forth above.


                              Very truly yours,
