ACCOUNTING POLICIES

Depreciation for the gas distribution segment is calculated using a
straight-line method for the calendar year.  For interim periods,
depreciation is allocated based on gas deliveries.  In April 1996, the gas
distribution composite depreciation rate was increased to 4.1 percent from
3.7 percent.

NEW ACCOUNTING PRONOUNCEMENT

In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, Earnings per Share.  This statement simplifies the standards for
computing earnings per share (EPS) and makes them comparable to
international EPS standards.  Statement No. 128 is effective for financial
statements issued for periods ending after December 15, 1997, and requires
restatement of all prior-period EPS data presented.  This statement is not
expected to have a material impact on the company's EPS.

RATE PROCEEDING

On April 3, 1996, the Ill.C.C. granted Nicor Gas a $33.7 million general
rate increase, of which $12 million relates to a change in the company's
composite depreciation rate.  The new rate structure, effective April 11,
1996, allows Nicor Gas to recover a larger proportion of its fixed costs
during warmer months.  In June 1997, the order was upheld by the Third
District Appellate Court of Illinois.

LONG-TERM DEBT

In October 1997, Nicor Gas issued $50 million of 7-3/8% First Mortgage Bonds
due in 2027.  The net proceeds from the sale of the bonds will be used,
together with other corporate funds, for the November 1997 retirement of $50
million of 9% First Mortgage Bonds due in 2019.

In June 1997, Nicor Gas sold $50 million of 6.75% First Mortgage Bonds due
in 2002.  The net proceeds from the sale of the bonds replenished corporate
funds used for the February 1997 maturity of $25 million of 5-1/2% First
Mortgage Bonds and general corporate purposes.

SHAREHOLDER RIGHTS PLAN

On September 9, 1997, the company's board of directors adopted a shareholder
rights plan.  Under the plan, shareholders of record on September 30, 1997,
were assigned one right for each share of Nicor common stock held.  The
rights will be exercisable only if a person acquires, or announces a tender
offer that would result in, ownership of 10 percent or more of Nicor's
common stock.  If a person acquires beneficial ownership of 10 percent or
more of Nicor's common stock, all holders of rights other than the acquiring
person will be entitled to purchase common stock of Nicor at a 50 percent
discount to the market price.  Nicor may redeem the rights at $.01 per right
at any time before someone becomes a 10 percent beneficial owner.  The
rights  expire on September 30, 2007.

CONTINGENCIES

The company is involved in legal or administrative proceedings before
various courts and agencies with respect to rates, taxes and other matters.

Current environmental laws require treatment of certain waste materials on
sites owned by Nicor that may have been generated by barge-cleaning
facilities previously owned and operated by certain discontinued businesses
of the company.  The cost of evaluation and cleanup is currently estimated
to range from $5 million to $15 million.  The company is evaluating whether
any of these costs will be recoverable from insurance or other sources.

Until the early 1950s, certain manufactured gas facilities were operated in
the Nicor Gas service territory.  Manufactured gas is now known to have
created various by-products that may still be present at these sites. 
Current environmental laws may require cleanup of these former manufactured
gas plant sites.  The company has identified up to 40 properties in its
service territory believed to be the location of such sites.  Of these
properties, Nicor Gas currently owns 15 and formerly owned or leased 13. 
The remaining properties were never owned or leased by the company. 
Information regarding preliminary reviews of the company's currently owned
and formerly owned or leased properties has been presented to the Illinois
Environmental Protection Agency.  More detailed investigations are either
currently in progress or planned at many of these sites.  The results of
continued testing and analysis should determine to what extent remediation
is necessary and may provide a basis for estimating any additional future
costs which, based on industry experience, could be significant.  Since
1994, the company has been recovering these costs from its customers in
accordance with Ill.C.C. authorization.

At certain sites, the current owners are seeking to allocate cleanup costs
to former owners or lessees, including Nicor Gas.

On December 20, 1995, Nicor Gas filed suit in the Circuit Court of Cook
County against insurance carriers seeking recovery of environmental cleanup
costs of certain former manufactured gas plant sites.  Presently, management
cannot predict the outcome of this lawsuit.  Any recoveries from such
litigation or other sources will be flowed back to the company's customers.

Although unable to determine the outcome of these contingencies, management
believes that appropriate accruals have been recorded.  Final disposition of
these matters is not expected to have a material impact on the company's
financial condition or results of operations.

Nicor Gas has entered into agreements to sell, subject to Ill.C.C. approval,
certain nonutility properties with a book value of approximately $6 million
for nearly $17 million.  Sale closings are expected to take place over the
next two quarters.

Item 2.  Management's Discussion and Analysis of Financial
         Condition and Results of Operations

OVERVIEW

The following discussion should be read in conjunction with the Management's
Discussion and Analysis section of the Nicor 1996 Annual Report on
Form 10-K.

Nicor's third quarter 1997 income from continuing operations increased to
$19.5 million from $15.1 million in the third quarter of 1996.  Earnings per
common share from continuing operations for the quarter were 40 cents
compared with 30 cents a year ago.  The increase was due primarily to
improved operating results and the positive impact of tax-related matters.

Income from continuing operations for the nine- and twelve-month periods
ended September 30, 1997, rose $2.6 million to $88.6 million and $2 million
to $123.8 million, respectively, from the corresponding 1996 periods.  The
increase in each period was primarily attributable to the positive impact of
tax-related matters which more than offset lower operating results. 
Earnings per common share from continuing operations were $1.81 and $2.52
compared with $1.71 and $2.42, respectively.  Per share results also
benefited from the company's common stock buyback programs.

Operating income (loss) for the periods ended September 30 by business
segment was (millions):

                     Three months      Nine months    Twelve months
                     1997     1996    1997    1996    1997     1996

                    $ 38.6   $ 35.3  $164.5  $169.4  $228.2   $233.3


The following summarizes operating income comparisons by business segment:

-    Gas distribution operating income for the three-month period
     increased $3.1 million due to higher deliveries of natural gas.  For
     the nine-month period, operating income decreased $3.9 million.  The
     decrease included the impact of a rate order that was implemented in
     April 1996 which included rate design changes and a depreciation
     rate increase. The rate design changes had a positive impact on 1996
     results but a negative impact on first quarter 1997 results when
     compared to the prior year.  Operating income for the twelve-month
     period decreased $.9 million due to higher depreciation.

-    Shipping operating income for the three-month period increased
     $.7 million due to an increase in volumes shipped.  For the nine-
     and twelve-month periods, operating income decreased $.5 million and
     $3.4 million, respectively, as higher operating costs more than
     offset the positive impact of an increase in volumes shipped.  All
     periods were impacted by lower revenue per unit related in part to
     changes in cargo mix.

RESULTS OF OPERATIONS

Details of various financial and operating information by segment can be
found in the tables on pages 11 and 12.  The following summarizes the major
changes in Nicor's revenues and expenses.

Operating revenues decreased $11.2 million for the three-month period and
increased $155.1 million and $281.7 million for the nine- and twelve-month
periods, respectively.  In each period the change was due primarily to
variances in the gas distribution segment's natural gas supply costs, which
are recovered from customers.

Gas distribution margin, defined as operating revenues less cost of gas and
revenue taxes, which are both passed directly through to customers, is shown
in the following table for the periods ended September 30.  For the three-
month period, margin increased due largely to higher deliveries of natural
gas.

                          Three months     Nine months    Twelve months
                          1997    1996    1997    1996    1997     1996

  delivered                1.35    1.35     .95     .93     .91     .89


Operating and maintenance expense increased $11.9 million and $22.1 million
for the nine- and twelve-month periods, respectively, due principally to
higher costs in the shipping segment caused primarily by increased volumes.

Depreciation expense increased in each period due primarily to the change in
the gas distribution composite depreciation rate and gas plant additions. 
For further information on the change in the composite depreciation rate,
see Accounting Policies on page 5.

Other income increased in each period due primarily to a change in interest
on income tax adjustments.

Interest on debt increased in the twelve-month period due to increased
borrowing levels and higher interest rates.

Item 2.  Management's Discussion and Analysis of Financial
         Condition and Results of Operations (Continued)    

FINANCIAL CONDITION

Net cash flow from operating activities increased $196.4 million and
$224.4 million for the nine- and twelve-month periods, respectively, due
primarily to the timing of gas cost recoveries in the gas distribution
segment.  Net cash flow from operations may swing sharply from one interim
period to another due to the seasonal nature of Nicor's businesses.  The
company generally relies on short-term financing to meet temporary increases
in working capital needs.

Estimated 1997 capital expenditures in the shipping segment have been
revised to $15 million primarily as a result of a decision to delay the
construction of two vessels.

The company has committed a total of $18 million to two new investments.  In
one transaction, Nicor will invest $10 million in a low income housing tax
credit fund.  In another transaction, an $8 million investment was made to
acquire an equity interest in a cargo container leasing business.

Nicor and its gas distribution subsidiary maintain short-term credit
agreements with major domestic and foreign banks.  At September 30, 1997,
these agreements, which serve as backup for the issuance of commercial
paper, totaled $280 million, and the company had $122.7 million of
commercial paper outstanding.  At September 30, 1997, the unused lines of
credit under these credit agreements were $157.3 million.

In October 1997, Nicor Gas issued $50 million of 7-3/8% First Mortgage Bonds
due in 2027.  The net proceeds from the sale of the bonds will be used,
together with other corporate funds, for the November 1997 retirement of $50
million of 9% First Mortgage Bonds due in 2019.

In June 1997, Nicor Gas sold $50 million of 6.75% First Mortgage Bonds due
in 2002.  The net proceeds from the sale of the bonds replenished corporate
funds used for the February 1997 maturity of $25 million of 5-1/2% First
Mortgage Bonds and general corporate purposes.

In June 1997, Nicor completed the $50 million common stock buyback program
initiated in June 1996 and announced another $50 million common stock
repurchase program.  Purchases under the new program will be made as market
conditions permit through open market transactions and to the extent cash
flow is available after other investment opportunities.  During the first
nine months of 1997, the company purchased and retired 1,062,100 common
shares at an aggregate cost of $36.9 million.

Effective with the dividend paid on May 1, 1997, Nicor's quarterly dividend
on common stock was increased 6.1 percent to 35 cents per share.

$1.2 billion pipeline designed to transport natural gas from the Canadian
border to the Midwest United States.  Current plans are to begin seeking
regulatory and other approvals this fall, with operations to begin by late
1999.

Customer Select Pilot Program.  On October 8, 1997, the Ill.C.C. approved
Nicor Gas' plans for a three-year pilot program called Customer Select that
will give more customers the opportunity to choose their natural gas
supplier.  Currently over 10 percent of the company's commercial and
industrial customers purchase natural gas from other suppliers, and in the
Customer Select pilot program, the remaining 150,000 commercial and
industrial customers will be eligible to choose their suppliers.  In the
first year, as many as 20,000 of those customers will be able to enroll in
the program.  In the year 2000, up to 10,000 residential customers will be
eligible to sign up.

Shareholder Rights Plan.  On September 9, 1997, the company's board of
directors adopted a shareholder rights plan.  For further information, see
Shareholder Rights Plan on page 5.
