Tree 2 — Yellow Transparent Apple. Was sprayed September 

 21st, 1904, with sohihlo pctroleuiii, one to three, imperfectly applied 

 with an atomizer. 



March 6th, 1905, was drenehod with Kerosene-Napthol, one to ten, 



April 2d, the buds wore well advanced; on the 30th leaflets were 

 unfolding and blossom buds ready to open, and on IMay 7th was 

 in full bloom and almost in full leaf. 



May 19tli, sprayed to a drench with arsenate of lead, one pound 

 in twenty gallons of water, and on the 29th repeated the application. 

 On the 25th a good set of fruit was obvious, and, while the bark 

 looked pretty rough, the tree was otherwise in good condition. 



June 2d, the lobes of calyx were closing. On the 25th a few larval 

 scales and recent sets were noticed, but nothing on the fruit, which 

 was developing well. Web-worms {Hyphantria) started at several 

 points, but never got beyond the first leaf or two. 



July 5th, sprayed with '"Anti-Scale," a petroleum preparation, one 

 to thirty, from the house side only, and on the 9th found both fruit 

 and leaves scalded and spotted by the application. Applied fish-oil 

 soap, one pound in four gallons of water, to reach those points that 

 the oil application had not hit. July 9th, the oil injury had inten- 

 sified, while no harm seems to have been done by the soap. On the 

 1 6th there were some worms where apples touched, but none from 

 the calyx end. On the topmost branches some of the fruits were 

 scaly, and these had evidently escaped the sprays. On the 20th and 

 21st, picked off all the fruits — nearly three baskets — not quite ripe, 

 but very attractive to boys. 



As the foliage was suffering from leaf-hopper, sprayed on the 

 morning of July 21st with fish-oil soap, one pound in six gallons of 

 water. A few hours later the loaf-hoppers were as active and numer- 

 ous as ever. On the 22d. sprayed with soluble petroleum, one to 

 twenty-five, covering very lightly. On. the 26th there Avas no appear- 

 ance of injury to the trees, while many of the leaf-hoppers had been 

 killed. jSTevertheless, these insects were yet abundant enough, in all 

 stages, to discolor the foliage and to cause some of the leaves to drop 

 early in August. On the 19th of the latter month, sprayed with 

 "Rose Nicotine," four ounces in two gallons of water, and applied 

 thoroughly. I actually saw the mixture hit and wet young and half- 

 grown forms, which four hours afterward were as lively as ever. 

 The :uaterial was absolutelv ineffective.
