guaranteed  return is valued at the lesser of cost plus  accreted

interest  or  market value.  For the six months  ended  June  30,

1997,  $1,321,155  of interest income has been  accreted  on  the

Yield Pool.  At June

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)



30,  1997,  the  cost of the Yield Pool was $43,704,541  and  the

accreted interest receivable thereon was $2,203,157.  The  market

value  of  the  Yield  Pool  on June 30,  1997  is  approximately

$45,085,403.



3.  Related Party Transactions

The  Partnership's  cash  is on deposit  with  DWR  in  commodity

trading accounts to meet margin requirements as needed.  DWR pays

interest  on  these funds based on current 13-week U.S.  Treasury

Bill  rates.  Brokerage expenses incurred by the Partnership  are

paid to DWR.



4.  Financial Instruments

The Partnership trades futures, forward contracts and options  in

interest rates, stock indices, commodities, currencies, petroleum

and  precious  metals.  Futures and forwards represent  contracts

for  delayed  delivery of an instrument at a specified  date  and

price.

Risk arises from changes in the value of these contracts and the

potential inability of counterparties to perform under the  terms

of   the  contracts.   There  are  numerous  factors  which   may

significantly  influence  the market value  of  these  contracts,

including  interest  rate  volatility.   At  June  30,  1997  and

December 31, 1996, open contracts were:

A  portion of the amounts indicated as off-balance-sheet risk  in

forward   currency   contracts  is  due  to  offsetting   forward

commitments to purchase and to sell the same currency on the same

date   in   the   future.   These  commitments  are  economically

offsetting,  but are not offset in the forward market  until  the

settlement date.



The  net  unrealized gains on open contracts are  reported  as  a

component  of  "Equity in Commodity futures trading accounts"  on

the  Statements of Financial Condition and totaled $1,521,198 and

$197,384  at  June 30, 1997 and December 31, 1996,  respectively.

Of  the $1,521,198 net unrealized gain on open contracts at  June

30, 1997, $1,523,894 related to exchange-traded futures contracts

and  $(2,696)  related  to off-exchange-traded  forward  currency

at December 31, 1996, $302,539 related to exchange-traded futures

contracts  and $(105,155) related to off-exchange-traded  forward

currency contracts.



Exchange-traded futures contracts held by the Partnership at June

30,  1997 and December 31, 1996 mature through September 1997 and

June  1997,  respectively.  Off-exchange-traded forward  currency

contracts  held by the Partnership at June 30, 1997 and  December

31,   1996  mature  through  September  1997  and  January  1997,

respectively.  The contract amounts in the above table  represent

the  Partnership's extent of involvement in the particular  class

of  financial instrument, but not the credit risk associated with

counterparty  nonperformance.  The credit  risk  associated  with

these  statements  is  limited to the amounts  reflected  in  the

Partnership's Statements of Financial Condition.




The  Partnership  also has credit risk because DWR  acts  as  the

futures  commission  merchant  or  the  sole  counterparty,  with

respect  to  most  of the Partnership's assets.   Exchange-traded

futures  contracts  are marked to market on a daily  basis,  with

variations  in  value  settled on a daily  basis.   DWR,  as  the

futures commission merchant for all of the Partnership's exchange-

traded futures contracts, is required  pursuant to regulations of

the Commodity

Futures  Trading Commission ("CFTC") to segregate  from  its  own

assets  and  for the sole benefit of its commodity customers  all

funds  held  by  DWR  with  respect to  exchange  traded  futures

contracts including an amount equal to the net unrealized gain on

all  open  futures contracts, which funds totaled $7,601,152  and

$6,927,864  at June 30, 1997 and December 31, 1996, respectively.

With  respect  to  the Partnership's off-exchange-traded  forward

currency  contracts, there are no daily settlements of variations

in value nor is there any requirement that an amount equal to the

net  unrealized  gain  on open forward contracts  be  segregated.

With   respect  to  those  off-exchange-traded  forward  currency

contracts, the Partnership is at risk to the ability of DWR,  the

counterparty on all such contracts, to perform.




For  the  six  months  ended June 30, 1997  and  the  year  ended

December   31,   1996,  the  average  fair  value  of   financial

instruments held for trading purposes was as follows:

5.  Subsequent Event

On  July  31,  1997,  DWR closed the sale  of  its  institutional

futures business and foreign currency trading operations to  Carr

Futures

Inc.   ("Carr"),  a  subsidiary  of  Credit  Agricole   Indosuez.

Following  the  sale,  Carr  became  the  counterparty   on   the

Partnership's  foreign  currency  trades.   However,   during   a

transition  period of about three months, DWR  will  continue  to

perform  certain  services relating to the Partnership's  futures

trading  including clearance.  After such transition period,  DWR

will  continue  to serve as a futures broker for the  Partnership

Carr   providing   execution  and  clearing  services   for   the

Partnership's account.














<PAGE>
Item 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
               CONDITION AND RESULTS OF OPERATIONS


Liquidity  - The Partnership's assets are on deposit  in  futures

interest  trading  accounts  with  DWR  and  are  used   by   the

Partnership as margin to engage in futures interest trading.  DWR

holds  such  assets  in  either  designated  depositories  or  in

securities approved by the CFTC for investment of customer funds.

The Partnership's assets held by DWR may be used as margin solely

for  the  Partnership's  trading.  Since the  Partnership's  sole

purpose is to trade in futures interests, it is expected that the

Partnership  will continue to own such liquid assets  for  margin

purposes.



The  Partnership's investment in futures interests may, from time

to time, be illiquid.  Most United States futures exchanges limit

fluctuations in certain futures interest prices during  a  single

day  by  regulations  referred to as  "daily  price  fluctuations

limits" or "daily limits".  Pursuant to such regulations,  during

a  single trading day no trades may be executed at prices  beyond

the  daily limit.  If the price of a particular futures  interest

has  increased  or  decreased by an amount equal  to  the  "daily

limit",  positions in such futures interest can neither be  taken

nor liquidated unless traders are willing to effect trades at  or

within  the  limit.   Futures interest prices  have  occasionally

moved the daily limit for several consecutive days with little or

no trading.  Such market conditions could prevent the Partnership

from  promptly  liquidating its futures interests and  result  in

restrictions on redemptions.  However, since the commencement of

                                

<PAGE>

trading  by  the Partnership, there has never been  a  time  when

illiquidity  has affected a material portion of the Partnership's

assets.



There  is  no limitation on daily price moves in trading  forward

contracts  on  foreign currencies.  The markets  for  some  world

currencies  have low trading volume and are illiquid,  which  may

prevent  the  Partnership from trading in potentially  profitable

markets  or  prevent  the Partnership from  promptly  liquidating

unfavorable  positions  in  such markets  and  subjecting  it  to

substantial  losses.   Either of these  market  conditions  could

result in restrictions on redemptions.



Capital  Resources - The Partnership does not have, nor  does  it

expect  to  have, any capital assets.  Redemptions and  sales  of

additional  Units of Limited Partnership Interest in  the  future

will  affect  the  amount of funds available for  investments  in

futures interests in subsequent periods.  As redemptions  are  at

the  discretion  of the Limited Partners, it is not  possible  to

estimate   the  amount  and  therefore  the  impact   of   future

redemptions.



Results of Operations

For the Quarter and Six Months Ended June 30, 1997

For  the  quarter  ended June 30, 1997, the  Partnership's  total

revenues,  consisting of net trading income, an increase  in  the

value  of  the  Yield Pool, and interest income were  $3,326,644.

During the second quarter, the Partnership posted an increase in

<PAGE>

Net  Asset  Value  per  Unit.  The most  significant  gains  were

recorded in the stock and bond portion of the balanced portfolio,

as  domestic  stock  and  bond prices  moved  higher  during  the

quarter. Trading gains were also recorded in the managed  futures

portion  of  the  portfolio  from long  Australian  bond  futures

positions   as   priced  moved  higher  during  May   and   June.

Additionally,  gains  during the quarter were  attributed  to  an

increase  in  the  value of zero coupon U.S. Treasury  Securities

held  in the guarantee portion of the Partnership.  A portion  of

the  Partnership's  overall gains was offset  by  losses  in  the

managed  futures portion of the balanced portfolio  from  trading

crude oil and natural gas futures, as oil and gas prices moved in

a  short-term volatile pattern during May and June.  Losses  were

also recorded in the currency markets from transactions involving

the  Italian lira, Swiss franc and French franc.  Total  expenses

for  the  quarter were $733,076, resulting in a net  gain  before

minority interest of $2,593,568.  The minority interest  in  such

gains was $20,993 resulting in a net income of $2,572,575 for the

Partnership.  The value of an individual Unit in the  Partnership

increased from $1,470.72 at March 31, 1997 to $1,547.07  at  June

30, 1997.



For  the six months ended June 30, 1997, the Partnership's  total

revenues  consisting of net trading income,  a  decrease  in  the

value  of  the  Yield Pool, and interest income were  $3,771,975.

During  the first six months, the Partnership posted an  increase

in  Net  Asset Value per Unit.  The most significant  gains  were

recorded in the managed futures portion of the portfolio  from  a

strengthening  in the value of the U.S. dollar relative  to  most

European

<PAGE>

currencies  during January and February.  Additional  gains  were

recorded in the stock portion of the balanced portfolio from long

S&P  500  Index futures positions as domestic stock prices  moved

higher  throughout  most of the first six  months  of  the  year.

Gains  were also recorded in the managed futures portion  of  the

portfolio  from long Australian bond futures positions as  prices

moved higher during May and June.  A portion of the Partnership's

overall  gains  was  offset by losses  recorded  in  the  managed

futures  portion  of  the  portfolio  from  trading  agricultural

futures,  as  prices moved in a choppy pattern during  the  first

half of the year.  Total expenses for the period were $1,486,450,

resulting  in net income before minority interest of  $2,285,525.

The minority interest in such gains was $32,960, resulting in net

income  of  $2,252,565  for the Partnership.   The  value  of  an

individual  Unit in the Partnership increased from  $1,479.85  at

December 31, 1996 to $1,547.07 at June 30, 1997.



For the Quarter and Six Months Ended June 30, 1996

For  the  quarter  ended June 30, 1996, the  Partnership's  total

trading losses net of interest income and change in value of  the

Yield  Pool  were  $429,413.   During  the  second  quarter,  the

Partnership posted a decrease in Net Asset Value per  Unit.   The

most significant losses were recorded in the bond portion of  the

balanced  portfolio  as U.S. Treasury bond futures  prices  moved

lower  during  April and May.  Additionally,  losses  during  the

quarter  were attributed to a decline in the value of  the  zero-

coupon U.S. Treasury securities held in the guarantee portion  of

the  Partnership.   Losses  were also  recorded  in  the  managed

futures

<PAGE>

component  of  the  portfolio as non-U.S. interest  rate  futures

prices  moved  in  a  trendless pattern throughout  the  quarter.

These  losses were partially offset by gains experienced  in  the

managed  futures portfolio from long corn futures  positions,  as

prices  increased  during  April and early  May,  and  from  long

natural  gas futures positions, as prices increased during  June.

Gains were recorded during April from short German mark and Swiss

franc  positions,  as  the  value of these  currencies  decreased

relative  to  other  world currencies, also  helped  to  mitigate

losses  experienced during the quarter.  Interest income declined

in  comparison  to 1995's second quarter because the  Zero-Coupon

U.S.  Treasury Securities held by the Partnership to support  the

Guaranteed  Return  matured during 1995 and were  replaced  at  a

lower  yield.   Total  expenses for the  quarter  were  $788,333,

resulting  in a net loss before minority interest of  $1,217,746.

The  minority interest in such loss was $23,789, resulting  in  a

net  loss  of  $1,193,957 for the Partnership.  The value  of  an

individual  Unit in the Partnership decreased from  $1,416.23  at

March 31, 1996 to $1,385.64 at June 30, 1996.



For  the six months ended June 30, 1996, the Partnership's  total

trading losses net of interest income and change in value of  the

Yield  Pool were $5,676,264.  During the first half of the  year,

the  Partnership posted a decrease in Net Asset Value  per  Unit.

The most significant losses were recorded in the bond portion, as

well  as the guarantee portion, of the portfolio as U.S. Treasury

bond  prices  moved dramatically lower during the first  quarter.

As

                                

<PAGE>

a  result,  the  Partnership's long U.S.  Treasury  bond  futures

positions  and  the Yield Pool recorded losses.   Smaller  losses

were  recorded in the bond portion during the second  quarter  as

the downward price movement continued into April and May.  In the

managed  futures component of the portfolio, losses were recorded

in  financial  futures  trading as global interest  rate  futures

prices  reversed  sharply  lower  during  February  and  remained

trendless  between March and June.  Smaller losses were  recorded

in  soft  commodities  and base metals as prices  were  trendless

throughout  the  first  half  of the  year.   These  losses  were

partially  offset by gains recorded during the second quarter  in

the agricultural markets from long corn futures positions, and in

the  energy  markets  from long natural  gas  futures  positions.

Gains  were  also recorded in the stock portion of the portfolio,

as  S&P  500  Stock Index futures prices moved higher.   Interest

income  declined in comparison to 1995's first six months because

the  Zero  Coupon U.S. Treasury Securities held  to  support  the

Guaranteed  Return  matured during 1995 and were  replaced  at  a

lower  yield.   Total  expenses for the period  were  $1,535,280,

resulting  in a net loss before minority interest of  $7,211,544.

The  minority interest in such loss was $115,594, resulting in  a

net  loss  of  $7,095,950 for the Partnership.  The value  of  an

individual  Unit in the Partnership decreased from  $1,562.26  at

December 31, 1995 to $1,385.64 at June 30, 1996.

                   PART II.  OTHER INFORMATION

Item 1.   LEGAL PROCEEDINGS

On  September 6, 10, and 20, 1996, and on March 13, 1997, similar

purported class actions were filed in the Superior Court  of  the

State  of  California, County of Los Angeles, on  behalf  of  all

purchasers  of  interests in limited partnership commodity  pools

sold  by DWR.  Named defendants include DWR, Demeter, Dean Witter

Futures  &  Currency Management, Inc., MSDWD  (all  such  parties

referred  to  hereafter  as the "Dean Witter  Parties"),  certain

limited  partnership  commodity pools of  which  Demeter  is  the

general partner, and certain trading advisors to those pools.  On

June  16,  1997,  the  plaintiffs in the above  actions  filed  a

consolidated amended complaint.  Similar purported class  actions

were also filed on September 18 and 20, 1996 in the Supreme Court

of  the  State of New York, New York County, and on November  14,

1996  in the Superior Court of the State of Delaware, New  Castle

County,  against  the  Dean Witter Parties  and  certain  trading

advisors  on  behalf  of all purchasers of interests  in  various

limited  partnership  commodity pools sold  by  DWR.   Generally,

these  complaints allege, among other things, that the defendants

committed  fraud, deceit, misrepresentation, breach of  fiduciary

duty,   fraudulent   and   unfair  business   practices,   unjust

enrichment,  and  conversion  in connection  with  the  sale  and

operation  of  the  various limited partnership commodity  pools.

The  complaints  seek  unspecified amounts  of  compensatory  and

punitive   damages  and  other  relief.   It  is  possible   that

additional  similar actions may be filed and that, in the  course

of these actions, other parties

                                

<PAGE>

could  be  added as defendants.  The Dean Witter Parties  believe

that  they  have  strong defenses to, and  they  will  vigorously

contest,  the  actions.  Although the ultimate outcome  of  legal

proceedings cannot be predicted with certainty, it is the opinion

of  management of the Dean Witter Parties that the resolution  of

the  actions  will  not  have a material adverse  effect  on  the

financial  condition or the results of operations of any  of  the

Dean Witter.



Item 5.  OTHER INFORMATION

On  July  21,  1997,  MSDWD,  the sole  shareholder  of  Demeter,

appointed  a  new  Board of Directors consisting  of  Richard  M.

DeMartini, Mark J. Hawley, Lawrence Volpe, Joseph G. Siniscalchi,

Edward C. Oelsner III, and Robert E. Murray.
