In order to assist town surveyors who may be required to act under this clause, I now give a verbatim copy of a “plan” or specification under which I compelled a gas company to work after they had given me the usual statutory notice of their intention to break up certain macadamised streets for the purpose of removing some disused mains. _Plan of the manner in which the              Gas Light and Coke Company shall take up and remove the old mains in        street, commencing at or near        street._ A trench to be excavated of not greater width than      inches and of no greater length than      feet at a time. Great care must be taken to keep the top facing metal separate from the lower formation of the roadway, so that they may not become mixed together; no metal is on any account to be removed from the street. The mains must be taken up with all possible speed and instantly conveyed away, without being allowed to remain at the sides of the streets.[129] The trench to be then at once filled in, care being taken to replace all the materials of which the roadway is formed in their proper positions. All extra filling in that may be required owing to the removal of the mains shall be done on the surface with the best          stone, broken so as to pass all ways through a ring of 2¹⁄₂ inches internal diameter, the top of the trench being always kept flush with the surface contour of the roadway. No earth, rubbish, or other material shall be allowed to be brought on to the ground by the gas company for the purpose of filling in, nor shall any material of any kind be allowed to be brought from any other excavations that may be being made by the gas company in other parts of the town for the purpose of laying or removing mains. The filling in to be done in the proportion of one man filling to two men ramming with punners of not less weight than      lbs. each. During dry weather a plentiful supply of water must be allowed to run into the trench whilst the filling in is in progress, for the purpose of consolidating the ground. The traffic must not in any case be impeded, and planks must be placed across the excavations, where necessary, for the convenience of foot passengers. The work shall if necessary be suspended on market days, or any other days that the surveyor may deem proper for the convenience of the public. * * * * * The next clause of the Act deals with the manner in which the companies shall reinstate and make good the road or pavement, and is as follows:
