quantities. The droppings of well-fed animals are all he 

 needs, if so preserved as to retain all their original con- 

 stituents, with no loss and no change of their relative 

 proportions of soluble and insoluble matter; that is, if 

 both the liquid and the solid portions, combined with a 

 little dried clay, or charcoal dust, or dry swamp soil, be 

 preserved with no deterioration till applied to the soil 

 they afford all that plants require. 



But as no one has yet been able to prescribe how they 

 can be obtained in sufficient quantity, and as not one 

 farmer in a thousand has yet learned to preserve them 

 in full value, it is well to inquire, what other fertilizers 

 are suited to tobacco ? Guano is good for this crop be- 

 yond question. Superphosphate of lime is good. In 

 soils pretty well supplied with barn manure, we think 

 that superphosphate plays a more important part in 

 making out the tobacco crop than guano. We would 

 apply both, say from 1 to 2 cwt. of guano, and from 

 2 to 3 cwt. of phosphate, depending somewhat upon how 

 much other manure is to be applied. 



Our idea is, that barn manure, composted largely with 

 leaf-mold, hedge-scrapings, swamp-muck, or something of 

 the kind, should be used plentifully, and, then, to supply 

 deficiencies in quantity with some of the' more portable 

 manures, as Peruvian guano, superphosphate, castor- 

 bean pomace, butchers' scraps, etc., etc. With reference 

 to the tobacco, as well as to the wheat, which is now 

 pretty generally made to follow it, we would certainly 

 apply more or less of both guano and of superphosphate, 

 not mixed, but separate, because the guano requires to 

 be covered deeply and diffused throughout the soil, while 

 the superphosphate should be left on or very near the 

 surface, the tendency of guano being to rise into the
