78 CULTUKE OF FARM CROPS. 



lighter ones, if purchased cattle food be liberally employed, 

 corn crops may be grown more frequently than is consist- 

 ent with what have generally been considered the estab- 

 lished rules of good farming, not only with pecuniary bene- 

 fit to the producer, but without injury to the soil. On 

 heavy soils barley of better quality may be obtained after 

 wheat than after a root crop. But when corn is taken 

 after corn, great attention should be paid to the cleansing 

 of the land, and manure should be liberally applied. When 

 wheat follows another corn crop, not less than 50 to 60 

 Ibs. of ammonia (or its equivalent of nitrogen in some 

 other form) should be applied per acre, and when barley 

 or oats follow a corn crop, from 40 to 50 Ibs. The quan- 

 tity of phosphate employed with the ammonia should be 

 greater for spring than for autumn sown corn crops."

 " Lois Weedon" mode of cultivating wheat so called from 

 the name of the vicarage of the Eev. Mr. Smith, its intro- 

 ducer it scarcely can be said to be a recently-introduced 

 system, inasmuch as it is now over twenty years since the 

 Rev. Mr. Smith commenced its practice. The main feature 

 of the system is growing a succession of crops of wheat 

 upon the same land and without manure. Strictly speak- 

 ing, the expression, " the same land," is scarcely correct, for 

 the same breadth of land is always under wheat, different 

 portions of that breadth only are under the crop directly. 

 This is brought about by the peculiar mode in which the 

 land is laid out in intervals of what may be called fallow and
