 but scattered over the surface, one shovel full following another and spreading over a considerable space.

Only a small space of road should be lifted at once; five men in a gang should be set to lift it all across: two men should continue to pick up and rake off the large stones and to form the road for receiving the broken stone, the other three should break stones—the broken stone to be laid on as soon as the piece of road is prepared to receive it, and then break up another piece; two or three yards at one lift is enough.

The proportioning the work among the five men must of course be regulated by the nature of the road; when there are many very large stones, the three breakers may not be able to keep pace with the two men employed in lifting and forming, and when there are few large stones the contrary may be the case; of all this the Surveyor must judge and direct.

But while it is recommended to lift and relay roads which have been made with large stone, or with large stone mixed with clay, chalk or other mischievous materials, there are many cases in which it would be highly unprofitable to lift and relay a road, even if the materials should have been originally too large.

The road between Cirencester and Bath is made of stone too large in size, but it is of so friable a nature that in lifting it becomes sand; in this case I recommended cutting down the high places, keeping the surface smooth and gradually wearing out the materials now in the road, and then replacing them with some stone of a better quality properly prepared.

In like manner a part of the road in the Bath district is made of freestone which it would be unprofitable to lift.

At Egham in Surrey, it was necessary to remove the whole road to separate the small portion of valuable materials from the mass of soft matter of which it was principally composed.
