tree, withiu a radius of from six to eight feet from the trunk. 

 This dressing is best applied upon a heavy- mulch of grass 

 or cut straw. The cutting back of the diseased branches to 

 the healthy wood ought to be carried out as general conside- 

 rations recommend. A repetition of the same treatment for 

 one or two seasons has been usually sufficient to correct the 

 new growth of the tree, provided the disease has not gone 

 too far before the remedies were applied. 



Besides the special treatment of the affected tree — as pre- 

 viously described — we have recommended as a general fer- 

 tilizer for a peach orchard the following composition, which 

 has served us well in past years : Broadcast per acre 400 to 

 450 lbs. acid bone phosphate, containing from 11 to 12 per 

 cent, of soluble phosphoric acid ; 125 to 150 lbs. of muriate 

 of potash, and 75 to 100 lbs. of crude sulphate of magnesia 

 (Kieserit). 



The latter compound is added for the purpose of assist- 

 ing in the diffusion of the potash, and securing available 



magnesia. 



This fertilizer is best applied partly late in the fall and 

 partly in the early succeeding spring. The fertilizer ought 

 to be applied with a view to supply existing wants, rather 

 than to promote excessive growth of wood.
