MARCH.] MANURE GREENT WHEATS. 



land is about 24d. per bushel. They are used in 

 the same way as furriers' clippings, from 1O to 4O 

 bushels per acre, and need pricking in, as dogs and 

 crows are very fond of them. They do not answer 

 on wet land, or in very dry seasons : indeed no- 

 thing does succeed in excessive dry seasons on these 

 soils. The trotters contain a considerable quantity 

 of lime, and are often adulterated with sand, and 

 sometimes considerable quantities of oak saw-dust 

 are mixed with them, which has been found not to 

 injure them. 



5. Malt-dust costs at the neighbouring inalt- 

 houses Is. per bushel heaped, and about a half- 

 penny per bushel carriage to the land. It is sown 

 by hand, from 24 to 32 bushels per acre, at the 

 same time with barley, and harrowed in with the 

 seed. It suits most soils and seasons. Malt-dust 

 quickly spends itself, and is therefore never sown 

 with wheat : as a top-dressing to wheat in March, 

 about 30 bushels per acre, it probably would suc- 

 ceed on these soils. Black malt-dust, or such as 

 falls through the kiln-plate in drying, is greatly 

 preferred to the white, on account of the seeds of 

 charlock (sinapis arvensis) with which it abounds 

 being destroyed by the heat. These chalk- lands, 

 under their present management, produce such 

 abundance of charlock, that they are generally 

 obliged to mow off the heads and flowers about the 

 middle of June, to prevent its entirely smothering 

 the corn. Charlock-seed so abounds with oil, that 

 it will lay for any length of time in the earth with-
