blossom May 7th, a second May 8tli, and Ijoth were done May 

 nth; one fruit had set May 27th, to dnip during early June. 



June 27th, the bark of the trunk and branches li oked as if 

 it had been pohshed, and most of the scales were dead, but some 

 were alive and breeding, as a few larvre and recent sets l)ore 

 witness. These increased in number until July 8th, at which 

 time the tree was sprayed w^ith the horticultural conipoiuid, 2 

 ounces in i gallon of w^ater. This kept the tree fairly clean 

 until August 29th, when it needed and received a second spray- 

 ing, with material as before. Even this left a residue, how- 

 ever, SO' that a month later the number of developing insects 

 was such that on October 19th sprayed with "Kill-O-Scale,'" 

 I part to water 20 parts. On the 23d, the little remaining 

 foliag'e w-as spotted, and no live scales were found, on such 

 examination as was made. 



XoN'cmlier 2d, the fdiage was all gone; there was scale all 

 over the tree, though nowhere bad, and all that were examined 

 were dead. All were oil-soaked, and came off readily. The 

 fruit buds were abundant, well developed, and there was no 

 appearance of injury caused by the oil. 



Tree 24 — Grccnshorongh Peach. Leaf buds were pointing 

 out all o\"er the tree April 26th, and a good start had been 

 made Mav 7th, not a blossom de\-eloping, liowever. June 27th. 

 the tree was foimd tO' be slightly infested, a few larvoe: crawling 

 about, and some recent sets already a]>parent 011 the leaves. It 

 was, therefore, included in the list sprayed July 8th_ with the 

 horticidtural compound. 2 ounces in i gallon of ^\ater. This 

 seemed to act as a stimulant to the insects, and, August 19th, 

 a second application was made, which, being washed by rain, 

 was supplemented by a third, made August 29th, all applica- 

 tions being of the same material and strength. This acted as 

 a slight check only, and, on September 26th, sprayed with the 

 soluble petroleum, i part to water 4 parts. September 28th, 

 it w^as noted that some O'f the leaves had been injured, but not 

 enough to cause them to drop, and, thereafter, no living scale 

 insects were noted except near the tips of the new growth. 



November 2d, the foliage was nearly all off; there were scales 

 all over the tree, but oil-soaked and no live insects under those 

 that were examined. The (iily appearance is c\er}-\\here 

 obvious, but the heavy set ■ of fruit buds seems to be entirely 

 normal, and without a]>pearance nf injury. 



Tree 25 — Apricot. April 17th, leaf buds were beginning to 

 point out ; the blossom Ixuls seemed to enlarge, and J noted that
