A corrugator may be made by bolt-ing a cross piece to the hounds of awagon tongue. Pointed shovel bladesmay be fastened in an upright posi-tion to the front of the cross piecesso they will project below a distanceof about 4 or 6 inches. There is noset rule for the depth or size of cor-rugations, they differ according tosoil. Some experience, usually isnecessary to get them right.
