The necessity for draining should have careful consideration. If there are many gardens in this country that are suffering from want of drainage, it is certain that there are at least as many which are bled to death by over-drainage. Gardens on slopes rarely want drainage. If in a bottom they will probably need it, but even then very few pipes will be required if the soil is light. What pipes are laid should converge on the lowest part, where a pond may be formed. Stiff clay will cost about £10 an acre to drain, light loam about £5 10s. The following may be taken as reliable: - Stiff clay: 2,904 12-inch pipes, in rows 24 feet apart, at 30s. per 1,000, £4 7s.; 176 rods of trench 30 inches deep, at 8d. per rod, £5 17s. 4d. - total, £10 4s. 4d. Light land: 1,815 pipes, in rows 24 feet apart, at 30s. per 1,000, £2 14s. 6d.; 100 rods of trench 36 inches deep, at 6d. per rod, £2 15s. - total, £5 9S. 6d.
