 of these parts are fitted to miniiiter powerfully to the 

 growth oi the plant. 



When the bones are applied whole, the eflfect is not 

 very marked at first, because they decay slowly in the 

 soil : it is also necessary to put on a larcrp quantity 

 per acre. The best '.I'd to 



powder, or to fine li > ushels 



of dust will produce a more immediate and abundant 

 result than 80 or 100 bushels of whole bones, althou j;h 

 of course the effect will be sooner over. An advanta- 

 geous way of using them, is to put on 8 to 10 bushels 

 of dust per acre, and half the usual quantity of fann-

1' ones, that have been tised by the glue- 



makers, are still quite valuable : they have lost the 

 greater part of their gelatine, but the phosphates re- 

 main; and the bones are so softened by the long 



boiling that they have tir ' ;n, as to decompose 



quickly, and afford an ii supply of food to 



plants. 



Another most important form of applying bones, is 

 in a St:' ition bysulphiuric acid(oil of vitriol). 



Thi.s is substance, costing by the carboy not 



more than 2J to 3 cents per lb. To every 100 lbs. of 

 bones, about 50 to 60 of acid are taken; if bone du-xt 

 b used, from 25 to 45 lbs. of acid is suificienU Tlie
