 12 cwt. ; rape cake and rape dust, 6 cwt. ; saltpetre, 160 lbs.; 

 sulphate of ammonia, the most useful of all perhaps in gar- 

 dens, 1 lb. to the square rod ; sulphate of magnesia, 1 lb. ; 

 sulphate of potash, 2 lbs. ; sulphate of soda, 2 lbs. ; super-

These are, in general, the quantities published on the 

 authority of the dealers, and adopted by Mr. Johnson in 

 1844 ; but the improved methods of applying them, and the 

 facilities with which the best article can be procured, instead 

 of the spurious, enable the cultivator to save from the quan- 

 tities named, except when the article is distinct and alone, as 

 sulphate of ammonia or sulphate of magnesia. The mixtures 

 sold by individuals and companies must be used according to 

 the dealers' directions, because they alone know the strength. 

 They are interested in telling us the best quantities, because 

 manuring being the most costly part of cultivation, drives 

 men to the best and cheapest market. Poittevin's disinfected 

 manure. Potter's guano. Hunt's guano. Lane's carbon. Lane's 

 humus, Law's patent manure, and some others, can only be 

 appreciated after being used as directed by the vendors. They 

 know the quantity most efficacious, taking price and useful- 

 ness into account. Many of these prepared manures are from 

 night soil, the most valuable of all if properly apphed ; and 

 it is to be regretted that a single shilling sliould be expended 

 in imported manures while millions of pounds' worth of the 

 soil in this country are washed away in rivers, to the detri- 

 ment of the water and the loss of the state. As, however, 

 nine-tenths of the community do not know how to apply it, 

 we will give a hint upon the subject. 



It is easily disinfected with sulphate or muriate of lime ; 

 and if mixed with its bulk of peat earth and dried, it will be 

 fit to transport anywhere, and will be found foui-teen to one 

 stronger than cow-dung.
