LIGHTING.
In the Parish of Clapham, 20 lamps burning 5 cubic
feet per hour, and 2 burning 10 cubic feet per hour have
been added, and 2 burning 5 cubic feet per hour discontinued.
Six lamps have been shifted in position.
An order has been given to convert 100 ordinary street
lamps to the new incandescent burners, also to discontinue
four of the obelisk lamps and erect electric arc lamps
instead thereof.
In the Parish of Putney, the whole of the public
lamps are now of the new and improved pattern, and are
fitted with incandescent burners. There are 531 lamps in
the district of the Wandsworth and Putney Gas Company,
and 92 in the district of the Brentford Gas Company, a
total of 623. The charge per lamp per annum formerly
by the Wandsworth and Putney Gas Company was £3 4s.
including gas, maintenance, cleaning, lighting, &c.; the
burners consumed 5 feet of gas per hour, and the illuminating
power was 16 candles. The charge for incandescent
lighting is for 4¼-feet per hour (the burner having an
illuminating power equal to 79 candles), and with maintenance,
cleaning, lighting, &c., amounts to £3 per lamp
per annum; to this, however, must be added the cost of
8 mantles per lamp per annum, and the wages of a man
attending to same, which increases the cost to a rate
equal to £3 11s. 6d. per lamp per annum, or an extra
cost of 7s. 6d. per lamp for the increase of the illuminating
power from 16 to 79 candles. The Brentford Gas
Company's charge for ordinary lamps burning 5 feet
per hour, and of 16 candle power was £3 14s. 5d. per
lamp per annum, the charge for gas being much higher
than that of the Wandsworth and Putney Company;
and in this case the total charge for incandescent lighting
