The company to keep the governors and burners in repair, and also the lanterns, at a fixed sum per lamp per annum.
The company to light and extinguish, and keep all lanterns clean, and all pipes, valves, etc., in repair.
The company to keep the lamp posts etc., properly painted after they are fixed by the urban authority. Lamps may be shifted or fresh lamps erected by the urban authority, on their paying the cost.
The company not to be compelled to supply gas to lamps which are beyond a certain distance of their existing mains, without compensation.
A certain pressure of gas must be maintained, to be ascertained by water gauges fixed at certain public places, or at such points as may be determined.
Any lamps burning under size or out, shall be immediately attended to by the company. A deduction in payment for gas by the urban authority to be made if neglect can be proved. An arbitration clause is necessary for this or other matters that may be disputed, and also a clause for determining the agreement upon notice being given.
In supplying gas to the public lamps by meter, either wet or dry meters may be employed, and these are fixed either in the lamp posts themselves or under the footpath. Sometimes each lamp has a separate meter, but in the generality of cases one meter fixed to a lamp gives the average of gas consumed by ten or a dozen of its fellows at the same level, and in the same neighbourhood. The difficulties arising from this system are:
(1.) The liability of the meters to get out of repair, especially in times of severe frost, or by vibration of traffic.
(2.) The first cost of providing and fixing the meters, and subsequent cost of repairs.
(3.) The trouble and cost of inspection and keeping the accounts.
