Note 1 - Summary of Significant Accounting Policies

         Nature of Operations.  Southwest Gas Corporation (the Company) is
comprised of two segments:  Natural gas operations (Southwest or the natural
gas operations segment) and construction services.  Southwest purchases,
transports, and distributes natural gas to customers in portions of Arizona,
Nevada, and California.  Natural gas sales are seasonal, peaking during the
winter months.  Variability in weather from normal temperatures can materially
impact results of operations.  Northern Pipeline Construction Co. (Northern or
the construction services segment), a wholly owned subsidiary, is a full-service
underground piping contractor which provides utility companies with
trenching and installation, replacement, and maintenance services for energy
distribution systems.

         Discontinued Operations.  In July 1996, the Company completed the
sale of the assets and liabilities of PriMerit Bank (the Bank) to Norwest
Corporation.  The results of operations of the Bank are shown as discontinued
operations in the accompanying financial statements.

         Basis of Presentation.  The consolidated financial statements
included herein have been prepared by the Company, without audit, pursuant to
the rules and regulations of the Securities and Exchange Commission.  Certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to such rules and regulations.  The preparation
of the consolidated financial statements requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the
reporting period.  Actual results could differ from those estimates.  In the
opinion of management, all adjustments, consisting of normal recurring items
and estimates necessary for a fair presentation of the results for the interim
periods, have been made.  It is suggested that these consolidated financial
statements be read in conjunction with the financial statements and the notes
thereto included in the Company's 1996 Annual Report to Shareholders, which is
incorporated by reference into the Form 10-K, and the 1997 First Quarter
Report on Form 10-Q.

         Intercompany Transactions.  During the six months ended June 30,
1997, the construction services segment recognized $18 million of revenues
generated from contracts with Southwest.  At June 30, 1997, accounts
receivable for these services was $3.2 million.  The accounts receivable
balance, revenues, and associated profits are included in the consolidated
financial statements of the Company and were not eliminated during
consolidation.  Statement of Financial Accounting Standards (SFAS) No. 71,
"Accounting for the Effects of Certain Types of Regulation," provides that
intercompany profits on sales to regulated affiliates should not be eliminated
in consolidation if the sales price is reasonable and if future revenues
approximately equal to the sales price will result from the rate-making
process.  Management believes these two criteria will be met.

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

The Company is principally engaged in the business of purchasing,
transporting, and distributing natural gas.  Southwest is the largest
distributor in Arizona, selling and transporting natural gas in most of
southern, central, and northwestern Arizona, including the Phoenix and Tucson
metropolitan areas.  Southwest is also the largest distributor and transporter
of natural gas in Nevada, and serves the Las Vegas metropolitan area and
northern Nevada.  In addition, Southwest distributes and transports natural
gas in portions of California, including the Lake Tahoe area in northern
California and high desert and mountain areas in San Bernardino County.

Southwest purchases, transports, and distributes natural gas to approximately
1,113,000 residential, commercial, industrial and other customers, of which
58 percent are located in Arizona, 32 percent are in Nevada, and 10 percent
are in California.  During the twelve months ended June 30, 1997, Southwest
earned 54 percent of operating margin in Arizona, 37 percent in Nevada, and
9 percent in California.  During this same period, Southwest earned 62 percent
of operating margin from residential customers, 23 percent from commercial
customers, and 15 percent from industrial and other customers.  These patterns
are consistent with prior years and are expected to continue.

Northern is a full-service underground piping contractor which provides
utility companies with trenching and installation, replacement, and
maintenance services for energy distribution systems.

Capital Resources and Liquidity

The capital requirements and resources of the Company generally are determined
independently for the natural gas operations and construction services
segments.  Each business activity is generally responsible for securing its
own financing sources.  The capital requirements and resources of the
construction services segment are not material to the overall capital
requirements and resources of the Company.

Southwest continues to experience significant population growth throughout its
service territories.  This growth has required large amounts of capital to
finance the investment in infrastructure, in the form of new transmission and
distribution plant, to satisfy consumer demand.  Southwest estimates
construction expenditures during the three-year period ending
December 31, 1999 will be approximately $468 million.  During the three-year
period, cash flow from operating activities (net of dividends) is estimated to
fund approximately one-half of the gas operations total construction
expenditures.  A portion of the construction expenditure funding will be
provided by $30 million of funds held in trust, at December 31, 1996, from the
issuance of industrial development revenue bonds (IDRB).  The remaining cash
requirements are expected to be provided by external financing sources.  The
timing, types, and amounts of these additional external financings will be
dependent on a number of factors, including conditions in the capital markets,
timing and amounts of rate relief, and growth levels in Southwest service
areas.  These external financings may include the issuance of both debt and
equity securities, bank and other short-term borrowings, and other forms of
financing.  Due to the significant size of the current construction program,
differences between estimated and actual results are expected to occur. 
Actual events, and the timing of those events, frequently do not occur as
expected, and can impact, favorably or unfavorably, anticipated cash flows.

For the twelve months ended June 30, 1997, natural gas construction
expenditures totaled $201 million.  Approximately 80 percent of these
expenditures represents new construction and the balance represents costs
associated with routine replacement of existing transmission, distribution and
general plant.  Financing for recent construction expenditures and for other
corporate purposes was provided primarily by the issuances of medium-term
notes in January, February and June 1997 totaling $75 million and a
$16 million issuance of commercial paper in February 1997.

Cash flows from operating activities during the six and twelve months ended
June 30, 1997 were negatively affected by increases in the cost of gas during
the fourth quarter of 1996 and first quarter of 1997.  Higher gas costs
coupled with refunds to customers of previously overcollected amounts shifted
the deferred purchased gas cost balance from a $46.4 million payable, at 
                                       
                                       6
 


June 30, 1996, to a $57.5 million receivable, at June 30, 1997, a $104 million
change.  Southwest must first seek regulatory approval before changing the
rates it charges for recovery of gas costs. 

The increase in the cost of gas resulted from several factors including
reduced natural gas storage supplies nationwide following colder-than-normal
temperatures in the East and Midwest during the winter heating season of
1995/1996.  Domestic storage supplies were not fully replenished during the
summer months of 1996 because natural gas prices did not fall as much as
expected, and companies were shifting to "just-in-time" delivery practices in
lieu of storage.  Reduced availability coupled with increased weather-related
demand for supplies during the winter heating season of 1996/1997 were the
primary reasons for the increased cost of natural gas.  These increases not
only impacted Southwest, but local gas distribution companies throughout the
country.

Southwest intends to file for recovery of the accumulated balances in all
applicable rate jurisdictions.  In  January 1997, Southwest submitted a
purchased gas cost adjustment (PGA) filing with the Public Service Commission
of Nevada (PSCN). In April 1997 the filing was amended.  If approved as
amended, the filing would result in annual increases of $12.4 million, or
11 percent, in the southern Nevada rate jurisdiction and $6 million, or
14 percent, in the northern Nevada rate jurisdiction.  Hearings on this filing
were held in July 1997 and a final decision from the PSCN is expected during
the third quarter of 1997.

In June 1997, Southwest submitted an additional PGA filing with the PSCN to
increase annual rates by $24 million, or 19 percent, in southern Nevada and
$8.6 million, or 17 percent, in northern Nevada.  This annual PGA filing
addresses the increased costs of natural gas since the beginning of 1997 as
well as an increase to recover costs previously deferred.

For the purposes of computing the ratios of earnings to fixed charges,
earnings are defined as the sum of pretax income from continuing operations
plus fixed charges.  Fixed charges consist of all interest expense
including capitalized interest, one-third of rent expense (which
approximates the interest component of such expense), preferred securities
distributions and amortized debt costs.

Contribution to consolidated net income declined $358,000 compared to the
second quarter of 1996.  Higher operating and financing expenses incurred
as a result of the expansion and upgrading of the gas system to accommodate
continued customer growth were nearly offset by improvements in operating
margin.

Operating margin increased $5 million, or eight percent, in the second
quarter of 1997 when compared to the second quarter of 1996.  The operating
margin improvement was primarily the result of general rate relief granted
in Nevada jurisdictions effective July 1996 and customer growth.  Southwest
added approximately 62,000 customers during the past twelve months, a six
percent increase. 

Operations and maintenance expenses increased $1.1 million, or two percent,
reflecting general increases in labor, purchased goods and services.  

Depreciation expense and general taxes increased $2.1 million, or
nine percent, as a result of construction activities.  Average gas plant in
service increased $169 million, or ten percent, as compared to the second
quarter of 1996.  The increase reflects ongoing capital expenditures for
the upgrade of existing operating facilities and the expansion of the
system to accommodate continued customer growth.

Financing costs increased $2.1 million, or 15 percent, over the prior
period.  This increase is primarily attributed to higher short-term
borrowings outstanding during the current quarter and an increase in 
long-term debt reflecting $75 million of medium-term note issuances during 
1997.  The increase in short-term debt reflects the need for short-term 
financing to cover higher gas costs experienced during the fourth quarter of 
1996 and first quarter of 1997.

Contribution to consolidated net income increased $7.3 million compared to
the six months ended June 1996.  The increase was the result of improvement
in operating margin, offset somewhat by higher operating and financing
expenses.

Operating margin increased $22.1 million, or 13 percent, during the six
months ended June 1997 compared to the same period in 1996 due primarily to
continued customer growth throughout the Southwest service areas, general
rate relief granted in Nevada jurisdictions effective July 1996, and more
favorable weather conditions during the first quarter of 1997 relative to
the first quarter of 1996.

Operations and maintenance expenses increased $2.4 million, or two percent,
reflecting increases in labor and maintenance costs along with incremental
operating expenses associated with providing service to the growing
Southwest customer base.

Depreciation expense and general taxes increased $3.6 million, or seven
percent, resulting from an increase in average gas plant in service of $162
million, or ten percent.  This increase reflects capital expenditures for
the upgrade of existing operating facilities and the expansion of the
system to accommodate new customers being added to the system.

Financing costs increased $3.5 million, or 12 percent, during the six
months ended June 1997 over the comparative prior period.  Average total
debt outstanding during the period increased due to the financing of
construction expenditures and working capital needs and included higher
short-term debt, the issuance of medium-term notes during 1997, and the
drawdown of IDRB funds held in trust.

Contribution to consolidated net income increased $10.6 million compared to
the corresponding twelve-month period ended June 1996.  The increase was
the result of an improvement in operating margin, offset somewhat by higher
operating and financing expenses.

Operating margin increased $40.9 million due to customer growth, rate
relief, and improved, but warmer-than-normal, weather conditions. 
Southwest billed an average of 63,000 more customers per month than during
the previous twelve-month period which contributed approximately $11
million of additional margin.  General rate relief granted in Nevada
jurisdictions effective July 1996 contributed $14 million.  Weather-related
variances between periods resulted in a $16 million increase in operating
margin from weather-sensitive customers.  On a weather-normalized basis,
operating margin would have been approximately $14 million greater than
actually reported for the twelve months ended June 30, 1997 and $30 million
higher in the previous period.

Operations and maintenance expenses increased $11 million, or six percent,
reflecting increases in labor and maintenance costs along with incremental
operating expenses associated with providing service to the steadily
growing Southwest customer base.

Depreciation expense and general taxes increased $6 million, or six
percent, as a result of construction activities.  Average gas plant in
service for the current twelve-month period increased $151 million, or
ten percent, compared to the corresponding period a year ago.  This was
attributed to the upgrade of existing operating facilities and the
expansion of the system to accommodate customer growth.  

Financing costs increased $5.3 million, or nine percent, during the twelve
months ended June 30, 1997 over the comparative prior period.  Average
total debt outstanding during the period increased due to the financing of
construction expenditures and working capital needs and included higher
short-term debt, the issuance of medium-term notes during 1997, and the
drawdown of IDRB funds held in trust.  Additionally, the current year
reflects the full annual cost of the $60 million issuance of preferred
securities in October 1995.

Rates and Regulatory Proceedings

  Arizona

In November 1996, Southwest filed a general rate application with the
Arizona Corporation Commission (ACC) seeking approval to increase revenues
by $49.3 million annually for both of its Arizona rate jurisdictions. 
Southwest is seeking rate relief for increased operating costs, changes in
financing costs, and improvements and additions to the distribution system. 
The rate application also proposes a number of rate design improvements
including consolidation of the southern and central Arizona rate
jurisdictions and better matching of rates with the costs of serving
various customer classes.  In June 1997 a settlement agreement was filed
with the ACC representing agreement among the principal parties to resolve
the rate case without a lengthy hearing process.  If approved as filed, the
settlement agreement would authorize an annual revenue increase of $32
million effective September 1997.  The ACC is expected to address the
settlement agreement filing at a hearing in late August 1997.

  FERC

In July 1996, Paiute Pipeline Company, a wholly owned subsidiary of the
Company, filed a general rate case with the Federal Energy Regulatory
Commission (FERC) seeking approval to increase revenues by $6.9 million
annually. Paiute is seeking rate relief for increased costs associated with
transmission system additions and improvements, higher depreciation rates,
operating cost increases including labor, and an increase in the allowed
rate of return.  Interim rates reflecting the increased revenues became
effective in January 1997, subject to refund until a final order is issued. 
In June 1997 a settlement agreement was filed with the FERC which calls for
a $3.2 million general rate increase.  A final order could be received by
the end of 1997.  The Company has been accruing a liability to customers
for the difference between the rates collected since January 1, 1997 and
the estimated amount of relief to ultimately be granted.

  California

Northern California Expansion Project.  In 1995, Southwest initiated a
multi-year, three-phase construction project to expand its northern
California service territory and extend service into Truckee, California. 
(See Note 8 of the Notes to Consolidated Financial Statements of the 1996
Annual Report to Shareholders, incorporated by reference into the Form 10-K, 
for additional background information.)  In July 1997, Southwest filed
an application requesting authorization from the California Public
Utilities Commission (CPUC) to modify the terms and conditions of the
certificate of public convenience and necessity granted by the CPUC in
1995.

In the new application, Southwest is requesting that the cost cap of $29.1
million, originally approved by the CPUC, be increased to $46.8 million;
that the scope of Phase III construction be revised to include 2,900 of the
initially proposed 4,200 customers; and that Southwest be permitted to
collect contributions or advances from customer applicants desiring service
in the expansion area who were not identified to receive service during the
expansion phases as modified within the new application.  Southwest has
proposed to recover the incremental costs above the original cost cap on a
dollar-for-dollar basis through a surcharge mechanism.

The modified filing, if approved as proposed, places Southwest in an
improved position to recover the costs of the expansion and earn a return
on its investment.  Management expects the CPUC to hold hearings on this
filing and issue a final decision by the end of 1997.

For the remainder of 1997, construction work on this project will be
limited to the installation of services and meters off existing mains for
approximately 900 additional customers at a cost of approximately $1
million.  Phase III, if approved as modified in the July 1997 application,
would be completed during the 1998 and 1999 construction seasons with
construction expenditures estimated at $11 million.

Recently Issued Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board issued two new
accounting pronouncements. Statement of Financial Accounting Standards
(SFAS) No. 130, "Reporting Comprehensive Income," establishes standards for
reporting and displaying comprehensive income and its components in a full
set of general-purpose financial statements.  The components are required
to be reported in a financial statement that is displayed with the same
prominence as other financial statements.  This statement becomes effective
January 1, 1998.  The Company is in the process of reviewing the
requirements of SFAS No. 130 and determining the placement and format of
the required disclosures.

The second pronouncement issued was SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information."  SFAS No. 131
establishes standards for the way that public business enterprises report
information about operating segments in annual financial statements and
requires that those enterprises report selected information about operating
segments in interim financial reports issued to shareholders.  The
statement becomes effective for 1998 annual financial statements.  The
Company is in the process of reviewing the requirements of SFAS No. 131,
and determining the content and format of the additional disclosures.
