Taking this natural and rational view of the sub- 

 ject it would be very unjust to any green crop which 

 is intended for manure to charge it with anything 

 but the seed. And this will reduce the expense of 

 this mode of improvement to a very low figure. 



Harris also says : " On heavy land we have not 

 yet been able to dispense with summer fallowing. 



JOHN JOHNSTON, rich as he has made his land, is 

 yet in the habit of Summer fallowing more or less 

 every year. 



His practice has been to top-dress his clover land 

 in the Fall, and the next Spring to plow it up, and 

 prepare the land for wheat by plowing it twice more, 

 with repeated harrowings, rolling, &c. In other 

 words, he manures the land in the Fall and then 

 gives it a good old fashioned Summer follow." 



Here, you perceive, are three plowings, and enough 

 of harrowing to seed the ground with two green crops, 

 and to turn them in when grown, without any extra 

 expense. And this tillage is never done all at once. 

 It is said that there should always be six or eight 

 weeks between each plowing. This method would 

 be very accommodating to nearly all kinds of green 

 manures. 



Observe how careful Johnston is, to neglect nothing 

 that will insure, him a large crop of wheat No won- 

 der he often raises 50 bushels per acre! We see 

 here that the whole of one year is devoted to the 

 preparation of the soil. 



He does not confine himself entirely to this mode. 

 Under another heading we will show that he plows 

 in clover in June for wheat. And notwithstanding
