In di-aining bog land, the subsoil of which is too unstable and treacherous to carry .either a tile or stone drain, it is the practice to cut out, first of all, a spit of some 18 inches, which is then left until the sides have become mode- I'ately dry and firm; then another spit; and so on until the drain is deep enough. During the cutting out of the drain, and the drying process which is the result of it, the surface of the bog sinks in pro- portion to the quantity of water that is with- drawn, and due allow- ance in depth of drain has to be made for this. Last of all, a spit, nar- rower than the others, leaving a shoulder on each side, is taken out of the bottom of the drain, and on the shoulders so left the first sod taken from the drain is placed, leaving beneath the opening represented in the annexed woodcut (Fig. 37). 18.
