The trench into which the drain pipes go is about five feet wide, and is first of all marked by large wooden piles, which are—driven down in order to prevent the falling in. The task of the ooolirs in making the trench cannot by any means be considered as pleasant, but they get on with it with tonishing alacrity.
The foundations, once the three foot line of slime has been passed, are more stable than was snticipated, and thus a considerable' amount of work at first planned out has been rendered unnecessary. When the required depth has been reached, a quantity of dry brick is placed at the bottom of the trench, and on this a foundation of cement about a foot deep is built for the pipes to rest upon. The pipes used are 4ft. ein. diameter, being made of reinforced concrete. After the laying' of the pipes, the filling in process is proceeded with. The piles are then removed and the whole thing levelled up. The inside of he pipes is roughly about ten feet ie-ow the surface of the road, and five feet below the bed of the creek.
