began to see the uselessness of this method. I then sprayed the 10 trees with 

 Paris green, with the astonishing result, that not one peach ripened on the 

 whole lot of 36 trees ; at one time it looked a bushel a tree. I looked at the 

 clock each time I went to jar, and on returning found the 36 trees took two and 

 one-half hours, and the 10 ran from 45 minutes to an hour each time, so that 

 you may see that for a large orchard this method is quite impracticable. 



I sprayed the whole of my other peach trees with Paris green at the rate 

 of one pound to 300 gallons of water, with the addition of four pounds of lime 

 to each coal oil barrel of water (say about 44 to 45 gallons.) 



The first spraying did not effect the foliage in the least, as rain came soon 

 after. I gave them all another spraying, and this did not seem to hurt them. 

 I gave a third spraying to a portion, and this time the leaves were scorched 

 badly, the peaches of some trees tumbled off, but at this time nearly all seem 

 to have fully recovered. But the spraying did not save them, as I lost all my 

 early Canadas, Amsden June, Early Alexander, Early Louise, and I only mar- 

 keted three twelve quart baskets, and this off trees which at first gave promise 

 of an enormous crop. 



I have nine trees of Early Rivers, six of which I sprayed the same strength 

 three times, with no injury on the six. I have twelve baskets nearly ripe, and 

 at present sound, on the unsprayed ones not a peach. 



The early peaches nearly ripened a great many, but then rotted. On 

 examination nearly, if not quite, all had been stung with curculio. 



Onthe2istand 22nd July, I caught several curculio at work on nearly 

 full-grown peaches." 



The loss of our Blake's early peaches which had been sprayed, was probably 

 due in a larger measure to the effect of plum rot (monilia), than to the attacks 

 of curculio, so that a judicious use of Bordeaux mixture and Paris green might 

 have saved the crop. No doubt there is danger of injuring the foliage by 

 repeated applications of Paris green, as there seems to be a slight residue left 

 on the leaf after each application, which is not washed off, and this accumulating 

 with repeated sprayings, finally affects the foliage injuriously. Care should there- 

 fore be exercised when making the last application, to see that it is slightly 

 weaker than those made previously.

With peaches, nearly or quite all of the pruning should be done in the spring. 

 There is so much risk of the new growth being killed, and, of course, it will 

 it will need to be cut out in the spring, that it is best to defer pruning until 

 reasonably early in the spring. The peach needs severe pruning annually from 

 one-third to one-half of the new growth should be cut out. This will aid 

 materially in securing a better quality of fruit. — Farm Life.
