BLACK BLIGHT IN WHEAT. 



larger in quantity, and finer in quality. > And if, 

 in the general course of cultivation, dung be 

 applied or given to the green crops, which pre- 

 cede the white or seed-crops, the luxuriance of 

 leaf, stalk, &c. will be produced in that form 

 which is most valuable, either as green food, 

 turnips, &c. or hay ; and the succeeding grain- 

 crops would, in no respect, be diminished ; and 

 the straw, from being free from disease, would 

 be much increased in value* 



From what I have stated, if two crops of 

 wheat be desired in four years, the better mode 

 of manuring for them is, to lay on the dung the 

 two first years for green crops, and take the two 

 wheat-crops following, in the last two years. 

 There never was a more widely mistaken notion, 

 than that a supply of dung given one year, can 

 be exhausted either in that or the following year, 

 by cropping with any thing, but by burying it 

 below reach of the roots, or so low that it be- 

 comes inert or poisonous ; the manure may be 

 worse than lost. 



Sir John Sinclair again very justly observes, 

 " By the improvements which may be effected 

 " by the observations of ingenious naturalists, and 

 " the experience of intelligent farmers, there is 

 " every reason to hope that the diseases of wheat 

 " may, in a great measure, be so mitigated in their
