Street Lighting by Municipal Plants.

The statutes relating to municipal light plants prescribe that
the excess of the estimated annual expense (including the grosd
expense of operation, maintenance and repair, interest on the
debt created to pay for the plant, depreciation, sinking fund
or debt requirements, and loss if any, in the operation of the
plant during the preceding year) over the estimated income
from sales to private consumers shall be included in the annual
appropriations for maintenance and in the tax levy. For this
excess, which it must thus raise by taxation, the city or town
receives its street and public building lighting. In some in-
stances electricity furnished to public buildings is metered,
charged at the same rates as to private consimiers, and paid out
of other appropriations in the same manner as though the plants
were privately owned. In some instances also specific appro-
priations are made for street lighting, presumably with the
number and type of lamps to be supplied in view. For these
reasons, while it is desirable to know from the standpoint of the
city or town as a municipal corporation what it is getting for
the money raised for the plant by taxation, and on a basis com-
parable with the cost to it of lighting its buildings and streets if
served by a privately owned plant, such results can only be ob-
tained by estimates of the electricity used in public buildings
where not measured, and computations of the cost per street
lamp based on the average number of lights used per day and
an apportionment between different types of lamps according to
the energy theoretically necessary to supply them. In the three
pages following, the data used in arriving at these results and
the results themselves will be found tabulated.

The second table is devised upon the theory that for all its
expenditure the municipality receives only its street lighting
and the income from its commercial business, and that the cost
of the former to the city or town is the difference between such
income and the entire cost of carrying on the business.

The towns of Middleborough, Wakefield and Westfield, and
the city of Holyoke operate gas plants, the first named since
Oct 31, 1893, the second since Aug. 7, 1894, the third since
June 1, 1899, and the last since Dec. 15, 1902.

The plant at Middleborough makes water gas, those at Wake-
field and Westfield coal gas, that at Holyoke coal and water
gas.

During the year 1911 examinations by the State inspector
for candle-power and purity were made eight times in Middle-
borough, four times in Wakefield, twelve times in Westfield and
seventeen times in Holyoke. Impurities prohibited by statute
were found five times in Middleborough and twice in Westfield.
The candle-power has been found below the legal standard twice
in Westfield.

The average price received in Holyoke for gas sold in the
year ending June 30, 1911, was $1.00 per thousand; in Middle-
borough, $2.59; in Wakefield, $1.28; and in Westfield, $1.20.
The cost of gas during the same period, computed by the method
applied fo the cost of electric lighting in the table on page 223
was, in Holyoke, $0.898 ; in Middleborough, $5.63 ; in Wake-
field, $1.21; in Westfield, $1.06.

226 GAS AND ELECTRIC LIGHT. [Jan.



DsrsPEcrioN of gas and gas meters

Gas Inspeotion.

Following the statutory requirement that the gas shall be
tested with a burner best adapted to it, which is at the same
time suitable for domestic use, the Board has continued the
use of the following burners in candle-power determinations:
the Sugg's London Argand burner, sizes D, old style, and D
and F, new style, with six or seven-inch chinmey, for coal gas,
low candle-power water gas and mixed coal and water gases ; the
Sugg's table-top, eight-foot size, and Bray's " slit-imion " jet,
seven-foot size, open burners, for the higher candle-power water
gases ; a small, one-foot size, iron tip open burner for oil gases,
and the von Schwarz " Perfection " one-half and three-quarters
foot sizes, for acetylene gas.

Of the 899 inspections made during the year ending Dec. 31,
1911, including those of gas supplied by municipal plants, 252
were made by the chief inspector.

The following tables contain .the data obtained by these ex-
aminations. For convenience of comparison the oil gas and
acetylene gas companies are shown in separate tables. The
Middleborough plant appears in two tables because of a change
during the year in the kind of gas made. In the ammonia
column, 1. — means that the gas did not contain as much as
one grain of ammonia per hundred cubic feet.
