on the land evenly, so that it will not interfere with 

 the cultivation or drilling in of the grain, it is ad- 

 visable to use a manure spreader. See III. 30. This 

 machine spreads the manure much more evenlv 

 than it can be done with a fork and does the work 

 very much more quickly. 



If the manure is not sufficiently rotted and inter-

under shallow, then rolled and harrowed. If the 

 subsoil is a tenacious clay it should be loosened with 

 a subsoil plow (see III. g) or a stiff-tooth cultivator 

 (see III. 48). If the subsoil is very hard it may be 

 necessary to cross cultivate in order to break up the 

 subsoil to a depth of about ten inches before sowing. 

 If the subsoil is sand or gravel, deep subsoiling is not 

 necessary. 



It is advisable to sow fall wheat with the grain 

 drill to secure a uniform depth. Finish off with a 

 spike-tooth harrow (77/. 5/) or a Breed weeder. 

 This prevents water from lodging in the creases made 

 by the grain spouts and freezing in winter, which 

 is liable to injure the wheat plants. With the fore- 

 going preparation a good wheat crop may be reason -
