PEACH AND THE PEAR. 265 



green manures — manures in which fermentation is still 

 going on. The reasons for this have been given when 

 speaking of the diseases of the peach, and will be 

 referred to again when I come to treat of the diseases of 

 the pear. The pear, like the peach, needs phosphoric 

 acid — potash, ammonia, and sometimes iron — and these, 

 with chlorine, may be applied in many shapes. The 

 prepared or artificial fertilizers, come in all shapes, and 

 are to be preferred. I like kainit, applied just as I have 

 recommended for peaches — and as there, we may mix it 

 with acid phosphate, one quarter or even one-half its 

 bulk, or weight, and apply broadcast or by drilling, after 

 ploughing in the spring, and then harrowing it in. Use 

 as much as you choose for pears, 200 lbs. to 1000 lbs. 

 per acre, as occasion may require. Use muriate of 

 potash alone — 3 to 5 lbs. to 10 lbs. to the tree, applied in 

 the spring, and harrowed in — or apply the potash mixed 

 with acid phosphate, 125 to 200 lbs. to the ton, and 

 drilled in in the spring, 200 lbs. to 1000 lbs. per acre. 

 Any good phosphate may be used, containing phosphoric 

 acid, potash and ammonia, drilled in in the spring, after 

 ploughing and harrowing, 200 lbs. to 1000 lbs. per acre. 

 Bone meal is good, but I prefer it undivided, as it acts 

 quicker. If you think your trees need iron, apply it as 

 in peaches. Sometimes liquid manures ; these same fer- 

 tilizers dissolved in water and applied little and often, 

 may be used with good effect to force large specimens of
