II H, '! 90 The Canadian Farmer's m iim :l^ 'il. One great advantage possessed by wooden drains over other kinds is, that from being of larger dimensions they do not require as great a fall; but they are subject to infesting by rats. A plan is often adopted to overcome this danger, by keeping the end about half dammed up with a good heavy turf, or by some other mean». This always keeps the lower end of the drain half full of water, but only for a certain distance up, so that while rats cannot easily g(3t up the drain, neither is the flow of water impeded excei)t for a certain distance from the mouth. Others put grat- ings of wire at the end ; these must, however, be carefully looked after, for they are apt to become stopped with silt coming down with the water. Wood will also last better in naturally wet soiL than in those of a drier nature, for as long as the wood is kept constantly wet it will hardly rot; it is dry rot that destroys a wooden drain. Tiles, when used, must be well burnt, and smooth within. Jf not well burnt, the wet is very apt to crack them. The bottom of a drain on which tiles are laid should be very carefully made—exactly the shape of the tile—so that the tile may, when placed in position, be supported on the sides closely by the bank, and lay touching the bottom at all points. To shape the bottom of the ditch aright, regular draining spades may be bought, and are required. Tiles should have a flow of from three to four inches when used as main drains ; when placed in lateral ditches a two-inch pipe IS s
