The  Partnership's  cash  is on deposit  with  DWR  and  Carr  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, options and forward contracts  in

interest   rates,  stock  indices,  commodities  and  currencies.

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, 1998 and December 31,  1997,  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  Consolidated Statements of Financial Condition  and  totaled

$107,220  and  $779,432 at June 30, 1998 and December  31,  1997,

respectively.

options contracts, are required, pursuant to regulations  of  the

Commodity Futures Trading Commission ("CFTC"), to segregate  from

their  own  assets  and for the sole benefit of  their  commodity

customers, all funds held by them with respect to exchange-traded

futures and futures styled options contracts including an  amount

equal  to the net unrealized gain on all open futures and futures

styled  options contracts, which funds, in the aggregate, totaled

$9,809,590 and $9,704,720 at June 30, 1998 and December 31, 1997,

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

Carr,  the  sole counterparty on all such contracts, to  perform.

Carr's  parent, Credit Agricole Indosuez, has guaranteed  to  the

Partnership  payment  of  the  net  liquidating  value   of   the

transactions  in  the Partnership's account with Carr  (including

foreign currency contracts).

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


Liquidity - The Partnership's assets are deposited with  DWR,  as

non-clearing broker and with Carr, as clearing broker in separate

futures   interest  trading  accounts,  and  are  used   by   the

Partnership  as  margin  to engage in futures  interest  trading.

Such assets are held in either non-interest bearing bank accounts

or  in securities approved by the CFTC for investment of customer

funds.  The Partnership's assets held by DWR and Carr 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   be

illiquid.  If  the price of a futures contract for  a  particular

commodity  has increased or decreased by an amount equal  to  the

"daily  limit," positions in the commodity can neither  be  taken

nor liquidated unless traders are willing to effect trades at  or

within  the  limit.   Commodity futures 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 commodity futures  positions  and

result in restrictions on redemptions.

                                

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

                                

<PAGE>

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  of  Units  of

Limited Partnership Interest in the future will affect the amount

of  funds  available  for  investment  in  futures  interests  in

subsequent  periods.   Since they 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, 1998

For  the  quarter  ended June 30, 1998, the Partnership  recorded

total revenues consisting of trading losses, interest income  and

change  in  value  of  the Yield Pool of $513,918  and  posted  a

decrease  in Net Asset Value per Unit after expenses.   The  most

significant  net  trading  losses were recorded  in  the  managed

futures  component of the balanced portfolio from long  positions

in Australian bond futures as prices moved lower during April and

June.  In currencies, losses were recorded during April and  June

from  crossrate transactions involving the Japanese yen  relative

to  the  Australian dollar as the value of Pacific Rim currencies

moved  in  a  short-term  volatile pattern  in  reaction  to  the

economic instability in that region.  Additional currency  losses

were

<PAGE>

recorded from short Singapore dollar positions as its value moved

higher  relative  to the U.S. dollar during June.   These  losses

were   partially  offset  by  gains  from  short  nickel  futures

positions  as  nickel  prices declined during  June.   Additional

gains  recorded  during June from short positions  in  crude  oil

futures and long positions in cotton futures helped to offset the

Partnership's overall losses.  Trading in the stock index futures

component  was  slightly  profitable for  the  quarter  as  gains

recorded  from long S&P 500 Index futures positions during  April

and  June offset losses recorded in this same market during  May.

Small  profits  were also recorded from long U.S.  Treasury  note

futures  positions.   Total expenses for the three  months  ended

June  30,  1998  were $701,988, resulting in a  net  loss  before

minority  interest of $188,070.  The minority  interest  in  such

loss  was  $27,713, resulting in a net loss of $160,357  for  the

Partnership.  The value of an individual Unit in the  Partnership

decreased from $1,788.81 at March 31, 1998 to $1,783.37  at  June

30, 1998.



For  the six months ended June 30, 1998, the Partnership recorded

total  trading revenues including interest income and  change  in

value  of the Yield Pool of $3,831,986 and posted an increase  in

Net  Asset  Value  per  Unit.  The most  significant  gains  were

recorded  from long S&P 500 Index futures positions in the  stock

index  portion of the balanced portfolio as domestic stock prices

climbed  to  record  highs during the first quarter.   Additional

gains  were recorded in the managed futures component from  short

crude  oil futures positions during January and February, as  oil

prices declined on news of a tentative agreement between the U.N.

<PAGE>

and   Iraq.   Short  crude  oil  futures  positions  also  proved

profitable during June as oil prices declined following a move up

higher  in March and April.  Gains were also recorded from  short

nickel futures positions as nickel prices moved lower during June

and  from trading livestock futures during February.  In the bond

futures  component, small profits were recorded  from  long  U.S.

Treasury note futures positions as prices finished the first half

of  the  year  slightly higher.  A portion of  the  Partnership's

overall gains for the first half of the year was offset by losses

experienced  in  the managed futures component  of  the  balanced

portfolio  from  long  positions in Australian  bond  futures  as

prices  moved  lower  during April and June.   Losses  were  also

experienced  in the currency markets from crossrate  transactions

involving  the  Japanese yen relative to  the  Australian  dollar

during  April  and June.  Smaller currency losses  were  recorded

from  short Singapore dollar positions as its value moved  higher

relative to the U.S. dollar during June.  Total expenses for  the

six  months ended June 30, 1998 were $1,448,479, resulting in net

income  before  minority  interest of $2,383,507.   The  minority

interest in such income was $25,367, resulting in a net income of

$2,358,140 for the Partnership.  The value of an individual  Unit

in  the Partnership increased from $1,707.59 at December 31, 1997

to $1,783.37 at June 30, 1998.



For the Quarter and Six Months Ended June 30, 1997

For  the  quarter  ended June 30, 1997, the Partnership  recorded

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

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

and

<PAGE>

posted  an  increase  in  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 prices 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 three months ended June 30, 1997 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 recorded

total  revenues consisting of net trading income, a  decrease  in

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

and  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

<PAGE>

relative to most European 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  six

months  ended  June 30, 1997 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.
