Supposing the pavement to be converted into a road, in that case, would it be necessary, when any pipe was repairing, to stop up the way to prevent carriages and horses passing?—Certainly not more so than at present, as that circumstance must always depend upon the width of the street. In very narrow streets, where the pipe lies in the centre, a large opening is necessary; it would follow as a matter of course that the street must be stopped; but upon large streets one side would be left free.
Would not a repair be more rapidly executed, supposing the way to be a road instead of a street?—Were the streets converted into roads, the repair of the roads would be almost unknown to the public, and no stoppage whatever would take place; the repair of such roads would be limited to a one-inch coat at a time, which would scarcely be known to persons passing in carriages, and the great inconvenience at present constantly felt in every part of this large metropolis by the necessity of repaving the streets would cease.
You assume that the roads for the streets in London must be made with granite?—Most assuredly, I should never recommend any other material to be made use of for the roads in the town.

I have heard some gentle-
