     Re:      The First Trust Combined Series 272

Gentlemen:

     We have acted as counsel for Nike Securities L.P., Depositor
The  First  Trust Combined Series 272 (the "Fund"), in connection
with  the  issuance of Units of fractional undivided interest  in
the  several  Trusts of said Fund under a Trust  Agreement  dated
September  29,  1999  (the "Indenture") between  Nike  Securities
L.P.,  as  Depositor, Securities Evaluation  Services,  Inc.,  as
Evaluator, and The Chase Manhattan Bank, as Trustee.

     In  this  connection,  we  have  examined  the  Registration
Statement, the form of Prospectus proposed to be filed  with  the
Securities and Exchange Commission, the Indenture and such  other
instruments  and  documents  as we have  deemed  pertinent.   For
purposes of the following opinions, it is assumed that each asset
of  the  Trust  is debt, the interest on which is  excluded  from
gross income for federal income tax purposes.

     Based  upon the foregoing and upon an investigation of  such
matters  of  law as we consider to be applicable, we are  of  the
opinion that, under existing federal income tax law:

          (i)    The  Trust is not an association  taxable  as  a
     corporation  but  will  be governed  by  the  provisions  of
     subchapter  J  (relating to trusts) of Chapter  1,  Internal
     Revenue Code of 1986 (the "Code").

         (ii)    Each Unit holder will be considered as owning  a
     pro  rata share of each asset of the respective Trust in the
     proportion  that the number of Units of such Trust  held  by
     him  bears to the total number of Units outstanding of  such
     Trust.   Under Subpart E, Subchapter J of Chapter 1  of  the
     Code, income of each Trust will be treated as income of each
     Unit  holder  of  the  respective Trust  in  the  proportion
     described,  and an item of Trust income will have  the  same
     character in the hands of a Unit holder as it would have  in
     the  hands of the Trustee.  Accordingly, to the extent  that
     the  income  of  a Trust consists of interest  and  original
     issue  discount excludable from gross income  under  Section
     103 of the Code, such income will be excludable from Federal
     gross  income of the Unit holders, except in the case  of  a
     Unit  holder who is a substantial user (or a person  related
     to such user) of a facility financed through issuance of any
     industrial  development  bonds or certain  private  activity
     bonds  held  by the Trust.  In the case of such Unit  holder
     who  is  a substantial user (and no other) interest received
     with  respect  to his Units attributable to such  industrial
     development  bonds  or  such  private  activity   bonds   is
     includable  in  his gross income.  In the  case  of  certain
     corporations, interest on the Bonds is included in computing
     the alternative minimum tax pursuant to Section 56(c) of the
     Code  and the branch profits tax imposed by Section  884  of
     the   Code   with  respect  to  U.S.  branches  of   foreign
     corporations.

        (iii)    Gain or loss will be recognized to a Unit holder
     upon redemption or sale of his Units.  Such gain or loss  is
     measured  by  comparing the proceeds of such  redemption  or
     sale  with  the adjusted basis of the Units.  If a  Bond  is
     acquired  with accrued interest, that portion of  the  price
     paid  for the accrued interest is added to the tax basis  of
     the  Bond.   When this accrued interest is received,  it  is
     treated as a return of capital and reduces the tax basis  of
     the  Bond.  If a Bond is purchased for a premium, the amount
     of  the premium is added to the tax basis of the Bond.  Bond
     premium  is amortized over the remaining term of  the  Bond,
     and  the  tax basis of the Bond is reduced each tax year  by
     the  amount  of  the  premium amortized in  that  tax  year.
     Accordingly, Unit holders must reduce the tax basis of their
     Units  for their share of accrued interest received  by  the
     Trust, if any, on Bonds delivered after the Unit holders pay
     for their Units to the extent that such interest accrued  on
     such  Bonds before the date the Trust acquired ownership  of
     the  Bonds (and the amount of this reduction may exceed  the
     amount  of  accrued  interest  paid  to  the  seller)   and,
     consequently,  such  Unit holders may have  an  increase  in
     taxable   gain  or  reduction  in  capital  loss  upon   the
     disposition of such Units.  In addition, such basis will  be
     increased by the Unit holders aliquot share of the  accrued
     original  issue discount (and market discount, if  the  Unit
     holder  elects to include market discount in  income  as  it
     accrues)  with respect to each Bond held by the  Trust  with
     respect  to which there was original issue discount  at  the
     time the Bond was issued (or which was purchased with market
     discount)  and  reduced by the annual amortization  of  bond
     premium, if any, on Bonds held by the Trust.

         (iv)   If the Trustee disposes of a Trust asset (whether
     by  sale,  payment on maturity, liquidation,  redemption  or
     otherwise) gain or loss is recognized to the Unit holder and
     the  amount  thereof  is  measured  by  comparing  the  Unit
     holders  aliquot  share  of the  total  proceeds  from  the
     transaction  with his basis for his fractional  interest  in
     the  asset  disposed  of.   Such  basis  is  ascertained  by
     apportioning the tax basis for his Units among each  of  the
     Trust  assets  (as  of  the date on  which  his  Units  were
     acquired)  ratably  according to  their  values  as  of  the
     valuation  date nearest the date on which he purchased  such
     Units.   A  Unit  holders basis in his  Units  and  of  his
     fractional  interest in each Trust asset must be reduced  by
     the amount of his aliquot share of accrued interest received
     by  the  Trust,  if any, on Bonds delivered after  the  Unit
     holders pay for their Units to the extent that such interest
     accrued  on  the  Bonds before the date the  Trust  acquired
     ownership of the Bonds (and the amount of this reduction may
     exceed  the amount of accrued interest paid to the  seller),
     must  be reduced by the annual amortization of bond premium,
     if  any, on Bonds held by the Trust and must be increased by
     the  Unit  holders  share  of the  accrued  original  issue
     discount (and market discount, if the Unit holder elects  to
     include  market  discount  in income  as  it  accrues)  with
     respect to each Bond which, at the time the Bond was issued,
     had  original  issue discount (or which was  purchased  with
     market discount).

          (v)    In the case of any Bond held by the Trust  where
     the "stated redemption price at maturity" exceeds the "issue
     price", such excess shall be original issue discount.   With
     respect to each Unit holder, upon the purchase of his  Units
     subsequent  to the original issuance of Bonds  held  by  the
     Trust,  Section  1272(a)(7)  of  the  Code  provides  for  a
     reduction  in  the accrued "daily portion" of such  original
     issue discount upon the purchase of a Bond subsequent to the
     Bonds original issue, under certain circumstances.  In  the
     case of any Bond held by the Trust the interest on which  is
     excludable from gross income under Section 103 of the  Code,
     any  original  issue  discount which  accrues  with  respect
     thereto will be treated as interest which is excludable from
     gross income under Section 103 of the Code.

          (vi)    We  have  examined  the  municipal  bond   unit
     investment trust insurance policies, if any, issued  to  the
     Trust on the Date of Deposit by AMBAC Assurance Corporation,
     Financial  Guaranty Insurance Corporation or  a  combination
     thereof.   Each  such  policy,  or  a  combination  of  such
     policies,  insures all bonds held by the  Trustee  for  that
     particular  Trust (other than bonds described  in  paragraph
     (vii))  against default in the prompt payment  of  principal
     and  interest.  In our opinion, any amount paid  under  each
     said  policy,  or  a  combination of  said  policies,  which
     represents maturing interest on defaulted Bonds held by  the
     Trustee will be excludable from Federal gross income if, and
     to  the  same  extent as, such interest would have  been  so
     excludable  if  paid in normal course by the Issuer  of  the
     defaulted Bonds provided that, at the time such policies are
     purchased,   the   amounts  paid  for  such   policies   are
     reasonable,  customary and consistent  with  the  reasonable
     expectation  that the Issuer of the Bonds, rather  than  the
     insurer, will pay debt service on the Bonds.  Paragraph (ii)
     of  this  opinion  is  accordingly applicable  to  insurance
     proceeds representing maturing interest.

        (vii)   Certain bonds in the portfolio of the Trust  have
     been  insured by the issuers thereof against default in  the
     prompt  payment  of  principal and  interest  (the  "Insured
     Bonds").   Insurance  has  been obtained  for  such  Insured
     Bonds,  or, in the case of a commitment, the Bonds  will  be
     ultimately  insured  under the terms of  such  an  insurance
     policy, which are designated as issuer Insured Bonds on  the
     portfolio  pages of the respective Trusts in the  prospectus
     for   the  Fund,  by  the  issuer  of  such  Insured  Bonds.
     Insurance  on  Insured Bonds is effective so  long  as  such
     Insured Bonds remain outstanding.  For each of these Insured
     Bonds,  we  have  been advised that the aggregate  principal
     amount  of  such Insured Bonds listed on the portfolio  page
     for  the  respective Trust was acquired  by  the  applicable
     Trust  and  are  part  of the series of such  Insured  Bonds
     listed  in the aggregate principal amount.  Based  upon  the
     assumption that the Insured Bonds of the Trust are  part  of
     the series covered by an insurance policy or, in the case of
     a  commitment, will be ultimately insured under the terms of
     such an insurance policy, it is our opinion that any amounts
     received  by  the  applicable  Trust  representing  maturing
     interest  on  such  Insured Bonds will  be  excludable  from
     federal  gross  income if, and to the same extent  as,  such
     interest  would  have been so excludable if paid  in  normal
     course  by  the  Issuer  provided that,  at  the  time  such
     policies  are purchased, the amounts paid for such  policies
     are reasonable, customary and consistent with the reasonable
     expectation  that  the issuer of the Insured  Bonds,  rather
     than  the  insurer,  will pay debt service  on  the  Insured
     Bonds.   Paragraph  (ii)  of  this  opinion  is  accordingly
     applicable to such payment.

     Sections 1288 and 1272 of the Code provide a complex set  of
rules  governing  the accrual of original issue discount.   These
rules provide that original issue discount accrues either on  the
basis  of  a constant compound interest rate or ratably over  the
term of the Bond, depending on the date the Bond was issued.   In
addition,  special rules apply if the purchase price  of  a  Bond
exceeds  the  original issue price plus the  amount  of  original
issue discount which would have previously accrued based upon its
issue  price  (its "adjusted issue price").  The  application  of
these rules will also vary depending on the value of the Bond  on
the date a Unit holder acquires his Units, and the price the Unit
holder pays for his Units.

     Because  the  Trust does not include any "private  activity"
bonds within the meaning of Section 141 of the Code issued on  or
after  August  8, 1986, none of the Trust Fund's interest  income
shall be treated as an item of tax preference when computing  the
alternative  minimum  tax.   In the  case  of  corporations,  for
taxable  years beginning after December 31, 1986, the alternative
minimum  tax  depends upon the corporations alternative  minimum
taxable income ("AMTI") which is the corporations taxable income
with certain adjustments.

     Pursuant to Section 56(c) of the Code, one of the adjustment
items  used in computing AMTI of a corporation (other than  an  S
corporation, Regulated Investment Company, Real Estate Investment
Trust, REMIC or FASIT) for taxable years beginning after 1989, is
an  amount  equal  to  75% of the excess  of  such  corporations
"adjusted  current  earnings" over an amount equal  to  its  AMTI
(before  such  adjustment  item  and  the  alternative  tax   net
operating loss deduction).  "Adjusted current earnings"  includes
all  tax-exempt interest, including interest on all Bonds in  the
Trust, and tax-exempt original issue discount.

     Effective for tax returns filed after December 31, 1987, all
taxpayers  are  required  to disclose  to  the  Internal  Revenue
Service the amount of tax-exempt interest earned during the year.

     Section  265  of the Code provides for a reduction  in  each
taxable  year of 100 percent of the otherwise deductible interest
on  indebtedness incurred or continued by financial institutions,
to  which  either Section 585 or Section 593 of the Code applies,
to  purchase or carry obligations acquired after August 7,  1986,
the  interest  on which is exempt from Federal income  taxes  for
such  taxable year.  Under rules prescribed by Section  265,  the
amount   of  interest  otherwise  deductible  by  such  financial
institutions  in  any  taxable  year  which  is  deemed   to   be
attributable to tax-exempt obligations acquired after  August  7,
1986,  will generally be the amount that bears the same ratio  to
the  interest  deduction otherwise allowable (determined  without
regard  to Section 265) to the taxpayer for the taxable  year  as
the  taxpayers  average adjusted basis (within  the  meaning  of
Section 1016) of tax-exempt obligations acquired after August  7,
1986, bears to such average adjusted basis for all assets of  the
taxpayer.  Legislative proposals have been made that would extend
the financial institution rules to all corporations.

     We  also call attention to the fact that, under Section  265
of  the  Code, interest on indebtedness incurred or continued  to
purchase or carry Units is not deductible for Federal income  tax
purposes.   Under rules used by the Internal Revenue Service  for
determining  when  borrowed funds are  considered  used  for  the
purpose of purchasing or carrying particular assets, the purchase
of  Units may be considered to have been made with borrowed funds
even though the borrowed funds are not directly traceable to  the
purchase  of Units.  However, these rules generally do not  apply
to  interest paid on indebtedness incurred for expenditures of  a
personal  nature  such  as  a mortgage incurred  to  purchase  or
improve a personal residence.

     "The  Revenue  Reconciliation Act of 1993" (the  "Tax  Act")
subjects  tax-exempt bonds to the market discount  rules  of  the
Code  effective  for bonds purchased after April  30,  1993.   In
general,  market  discount is the amount (if any)  by  which  the
stated   redemption  price  at  maturity  exceeds  an  investors
purchase  price  (except to the extent that such  difference,  if
any,  is attributable to original issue discount not yet accrued)
subject  to  a  statutory de minimis rule.  Market  discount  can
arise  based on the price a Trust pays for Bonds or the  price  a
Unit  holder  pays  for his or her Units.   Under  the  Tax  Act,
accretion of market discount is taxable as ordinary income; under
prior  law,  the  accretion  had been treated  as  capital  gain.
Market discount that accretes while a Trust holds a Bond would be
recognized as ordinary income by the Unit holders when  principal
payments  are  received on the Bond, upon sale or  at  redemption
(including  early redemption), or upon the sale or redemption  of
his  or  her Units, unless a Unit holder elects to include market
discount in taxable income as it accrues.

     Chapman and Cutler has expressed no opinion with respect  to
taxation under any other provisions of Federal law.  Ownership of
the   Units   may  result  in  collateral  Federal   income   tax
consequences to certain taxpayers.  Prospective investors  should
consult  their tax advisors as to the applicability of  any  such
collateral consequences.

     We  hereby  consent  to the filing of  this  opinion  as  an
exhibit  to  the  Registration  Statement  (File  No.  333-22615)
relating  to the Units referred to above and to the  use  of  our
name  and  to  the  reference of our firm  in  said  Registration
Statement and in the related Prospectus.

                                Very truly yours,
