Into ment, and mix it with coarse sand. Fine this pour boiling hot coal-tar; mix, and when sand will not do at all. 1 part cement and 3 as stiff as mortar put it 3 inches thick where parts sand is the usual proportion, to be used the walk is to be; the ground should be dry, and beaten smooth. Sprinkle over it coarse sand. When cold, pass a light roller over it; in a few days the walk will be solid and waterproof. as soon as mixed. Every part of the wall must be laid below the reach of the frost.

When sunk into the ground, for 8 or 10 inches, to keep weeds from growing through, and over this the gravel is to be laid 6 or 8 inches thick. This should be laid rounding up in the middle, by which means the larger stones will run off to the sides, and may be raked away; for the gravel should never be screened before it is laid on.

The walks should always be rolled 3 or 4 times after very hard showers, which will bind them more firmly than could be accomplished by any other method.
