and set jui immense crop of peaolies. The foliage came out a rich 

 luxuriant j^reen, free from leaf curl or other fun^l. There was no 

 June drop on these trees, so we had to thin more than usual. They 

 matured a large crop of choice peaches which sold for the highest 

 prices. Upon examination in the fall, we found these trees com- 

 paratively clean, healthy and with a full set of large healthy buds. 



Block No. 2, consisting of ten rov.s of larg-e peach trees, was 

 treated as follows: Formula, 50 pounds of lime, 45 pounds of sul- 

 phur, L*24 pounds of salt, 150 gallons of water, prepared by boiling 

 one hour and thirty minutes. 



This block of peach trees had u ravine washed through the middle 

 rendering is impossible to spray the full length. We sprayed back 

 and forth at one end, completing six rows to the gutter on the first 

 day. Bad weather then set in. Rain and high winds continued for 

 one week. By that time the blossoms were opening. I was fearful 

 of destroying the crop and as scale did not show up plentiful in this 

 block, I decided not to spray further. 



Results. Trees all set a full crop of fruit. June drop was con- 

 siderably more on the unsprayed trees. Also more leaf curl and 

 more fungus spots on the fruit. Foliage on sprayed trees was a 

 richer green. Sprayed trees j)roduced twice as many and finer fruit 

 than unsprayed trees. The scale on sprayed trees were nearly all de- 

 stroyed. vScarcely a live scale can be found. Unsprayed trees in 

 the six rows and four remaining rows on side are one mass of scale 

 with many limbs dviug. 



No. 3. Had one Mammoth Black twig apple tree very full of 

 scale. This tree was sprayed very heavy and complete just before 

 the buds opened. 



Results. Leaf, also fruit buds opened with unusual vigor. Al- 

 though this variety is subject to leaf fungi, w'hich frequently attack 

 the bloom and causes almost the entire crop to drop. Those remain- 

 ing are badly affected with scab. Such is the case this year on un- 

 sprayed trees of this variety. Yet on the spraj'ed trees fruit set 

 full, perfect in form and clean from scab. On close examination at 

 the beginning of October we were unable to find one living scale and 

 could find but two imperfect apples. 



When to spray? Undoubtedly the best time is just before the buds 

 open. But any one having a great number of trees will find it im- 

 possible to spray all at this time. Frequently bad weather holds 

 sway at this very time. So we must take advantage of fine weather 

 anytime through the wiuter; although I doubt if it 4s as efficacious 

 as when applied just before buds expand. As to how late we can 

 spray, the following will show: On going carefully over my or- 

 chard in May I found one peach tree very badly infested, so much so 

 r knew it would be killed before the season was past, besides act-
