charcoal or gypsum, after breaking the lumps and sifting in 

 alternate layers. Avoid the use of ashes or lime, as they 

 tend to expel the ammonia. Keep it under cover, beyond 

 the reach of water or rains, until used. It may then be 

 scattered broadcast upon meadows or grain, or placed near 

 the seeds or young plants in the hill.

NOTE. The most powerful substances in the above table, 

 viz., dry woollen rags, horn shavings, cow hair, feathers, &c., 

 hold little or no water, and contain the fertilizing elements 

 of the others in very compact forms. They show less im- 

 mediate sensible effect upon the crop than the others, because, 

 being so dry and compact, they are long decomposing, but 

 continue to evolve fertilizing matter long after the softer and 

 more fluid manures have spent their force.
