ful manures. Horns and hoofs are compounded of 
albumen and gelatine ; bones, of the phosphate and 
carbonate of lime and gelatine; shells, of carbo-

directly or indirectly, to wheat crops? 
- The practice, on this head, is different in different 
places. In France, as in all other countries, where

weeds brought into the field by the manure, start 
with the grain, and do as much harm as the dung does

know of, to this objection. The English practice 
is, therefore, much to be preferred; because, be-
