that the whole expense of boards and sheds was saved in the first month. 
The same boards will last at least one season more, and if better timber 
had been used, for a much longer period.

III. — On the Use of Sulphuric Acid with Bones as Compost. 
Bj P. Davis. 
With reference to Mr. Pusey's suggestion as to the propriety of 
using bone-dust (dissolved in sulphuric acid) along with compost instead 
of water for turnips, I can confirm his idea from practice, having last 
year manured 5 acres with only 13 bushels of bone-dust dissolved in 
270 lbs. of sulphuric acid and 150 gallons of water. After standing 
twenty-four hours, the liquid was mixed with 3 cart-loads of coal-ashes, 
and left to remain for a week, during which time it was turned over two 
or three times. Tlie mixture was then drilled along with the seed, and 
tlie result w as a fair crop of common turnips, off a ])iece of poor land, 
without other manure, and at the cost of only 12s'. 9(/. per acre.
