With regard to Ammonia, a valuable residual product of gas
manufacture, the limit allowed by the Acts of Parliament (4
grains in 100 cubic feet of gas) was not reached on any occasion.
The Chief Gas Examiner is quite independent of the Company
; it is satisfactory therefore to note that his reports of
the testings are so favourable, but I still think it would be
well if an arrangement could be effected to obtain systematic
records of pressure at all hours of the day and night, and at
several points in the Company's District within the Parish.
No complaint was received from any private consumer in
respect of the illuminating power of the gas, in 1882, and I
understand that Mr. Philip Monson,your Vestry's Superintendent
of Street Lighting, is satisfied with the quality of the gas
as supplied to the public lamps. The burners now in use are
calculated to consume gas at the rate of 4.5 cubic feet per hour,
whereas the burners formerly in use, originally provided when
Cannel gas was employed, consumed only 3 feet per hour ; but
notwithstanding the increased consumption of gas (50 per cent.)
and the consequent improvement in the lighting of the public
thoroughfares, the cost is not greater than under the old system
of a fixed annual payment per lamp.
