ment, phosphoric acid, and 8 the form in which it may be obtained. 

 The formulas are based on the suppoi^ition that the sulphate of 

 ammonia contains 24 per cent., the sulphate of potash 35 per ceut., 

 and the muriate of potash 80 per cent, dry salt, and the super- 

 phosphate 13 per cent, of soluble phosphoric acid. Of course, 

 should the articles vary from this standard in quality, the amount 

 used should be proportionally diminished or increased as the 

 articles are stronger or weaker. For example, if the superphos- 

 phate used contains 18 per cent, soluble acid, divide the number 

 in column 8 by 18 and multiply by 13.

The mixture is purely mechanical, but the more thoroughly the 

 ingredients are mixed the better. Apply the mixture to the sur- 

 face after plowing, and cultivate or harrow it in. If you feel a 

 little " ticklish " about it, strew it along the line of the furrow, 

 and then go along and plant your crop, but never do such a thing 

 as drop it in the hill. 



The following questions were put to Prof. Stockbridge, and 

 answered as fjllows : 



Question. Do or do not plants derive benefit from the ammonia 

 escaping from barn-yard manure in the process of decomposition ? 



Answer. Barn-yard manure has in it a large percentage of 

 nitrogen. I have already stated that nitrogen in the form of sole 

 leather was good for nothing, because it was not developed. la 

 the form of barn-yard manure it is good for nothing uutil it is 

 developed. Now I understand the question to be, if this decom-
