an increase of at least three bushels of wheat may 

 be secured. This is all due to the residual action of the 

 manure and the better cultivation of the land. The arver- 

 age value of this wheat would be about $4.50. 



"The additional straw from the larger crop of wheat is 

 converted into manure and returned to the soil. Suppose 

 that clover be sown with the wheat. The manure that the 

 land has received would insure a better stand of clover, 

 and, in fact, it might be the deciding factor as to whether 

 any clover at all would be obtained. It has been shown 

 by experiments that one ton more of clover per acre 

 may be secured on manured land than on that left unma- 

 nured. Not only can a ton more of clover be obtained, 

 but there will be more and better pasture. It is hard to 

 assign a value to this crop because of both its feeding 

 and manurial value, but it will be worth at least $5.25. 

 After growing clover, the land will increase in crop-pro- 

 ducing value. If the clover is followed by wheat, there 

 should be an increase of nine bushels over land receiving 

 no manure, making crop-producing value of the farm 

 manure and clover equal to $5.25 for the fourth year. If 

 the wheat is followed by oats, a further increase should 

 be secured. The oats are worth $3. During the five 

 years the increase in the value of the crops where farm 

 manure was used, clover grown, and better cultivation 

 given to the land should be $24. This makes the value 

 of the manure $3 per ton distributed over a period of 

 five years." 



Why should we longer deny our old lands the beneficial 

 influences of stable manure? Why should we longer 

 neglect it and abuse it? Why should we longer offer it 

 the least consideration of all products of the farm?
