collects in the side drains through the cutting to run off to the side drains before it reaches the embankment. For want of this precaution, embankments frequently suffer very much.


Depôts should be made on the sides of all roads for holding materials.

The best form is that which will serve to measure the quantity of materials, as well as to hold them. The back walls should be twelve yards long,

and the two side walls each two yards and a half at the bottom, and to slope at an angle of 45° to the to: the height of the back and sides should be three feet. A depôt of this form and dimensions will hold twenty-four cubic yards of materials; and four of these depôts on a mile, at 428 yards apart, will contain 100 cubic yards.

The depôts should not in any case be placed farther from each other than a quarter of a mile, so as to admit of moving the materials in barrows. This method is better calculated for constant repairs, than that of drawing them with carts and horses.

The top of the back, sides, and slopes to be coped with large stones, set on edge, and laid in good mortar.

“ The bottom is to be flagged with sandstone, in the rough, neatly jointed and evenly bedded.

“ The back and ends of the depôts to have a mound of earth thrown up against them, eighteen inches high on the outside, and eighteen inches or two feet on the base, rounded off on the top, and faced with sod if necessary, and the regular quantity of quicksets planted in it, which are to be protected by the field row of posts and rails before described : a tile drain to be laid in front of the depôt; it is to be thirteen yards long and ten inches in the square.” (See Plate IV. fig. 7.)

Specification for building Depôts with Bricks.

“ Four depôts for holding repairing materials are to be erected, in each mile of road, in such places as may be pointed out by the inspector: they are to be built of brick, twelve yards long in the clear, three feet high above the side channels of the road; the foundations to be deep enough to give stability to the work; the ends to be two yards and a half clear at the bottom, and to rise one yard and a half at top; the thickness of the back and ends to be nine inches. The upper course of bricks are to be laid on edge in cement; the ends are to be secured by an oak post driven three feet in the ground, and rising one foot above the surface; the bottom is to be paved with brick on edge, and an oak plank is to be set in front the whole length of the depôt, and flush with the upper surface of the pavement; it is to be three inches thick and six inches deep, secured at the ends by the oak posts before mentioned, and strengthened in the middle by a post driven two feet into the ground, and of a scantling not less than four inches by six inches.

“ The back and ends of the depôts are to have a mound of earth raised behind them eighteen inches deep and two feet wide, and faced with green sod; in this mound the quicks are to be set, which are to be protected with one row of posts and rails, as above described, set on the field side. A drain is to be made in front, of brick or tiles, so as not to interrupt the passage of the water in the inner side drain.”
