August 26tli, applied No. 3 kerosene-resin emulsion, at the rate of 

 one part to forty parts of water, to two shoots, to test the effect on 

 foliage. No appearance of injury on the 27th. The same shoots were 

 sprayed a second time and examined on the 31st. At that time there 

 were few larvge or recent sets left and some benefit had undoubtedly 

 resulted from the application. 



Injury did not intensify, and the scale-breeding seemed to have 

 been decidedly checked on September 13th. October 1st there was 

 only a skimpy lot of foliage, and while there was considerable scale 

 at some points, the bulk of the tree was practically clean. Attempted 

 to spray October 34th, but the wind prevented that. On the 30th 

 sprayed thoroughly with '"Scalecide," one part to water twenty parts. 



Tree 26 — Nectarine. Just starting April 12th; first blossom out on 

 the 27th; full bloom April 30th; out of bloom and in full leaf May 

 11th. A rather bad attack of leaf -curl began to develop at this time, 

 accompanied by gummy exudations from some of the branches, so 

 that by the end of May it looked rather ragged. During June con- 

 ditions improved until about the last of the month, when a very 

 heavy brood of young scales made its appearance and in early July 

 demanded attention. 



July 5th, sprayed thoroughly with "Anti- Scale," at the rate of one 

 to thirty of water. Injury developed during the days next following 

 and some of the foliage dropped. Many of the scales were killed, but 

 the brood was so tremendous that some remained over and new larv^ 

 were again numerous July 9th. Some of the remaining leaves were 

 badly spotted and these spots formed holes as the season advanced, 

 giving the tree a ragged appearance. 



A small set of fruit was made, which developed very slowly, and 

 not until about the first of October did it mature about a dozen 

 indifferent fruits of irregular size. 



August 19th, the second broom of larvge was in evidence, and later 

 the tree was always full of moving young and recent sets. The 

 foliage was still in very fair shape October 24th, when most of the 

 trees were sprayed, but high wind prevented application to this. 

 October 30th, sprayed thoroughly with "Scalecide," one part to water 

 twenty parts. 



Tree 29 — Gravenstein Apple. On March 6th, sprayed thoroughly 

 with Kerosene-Napthol, one part to ten parts of water. The tree 

 started early in April, leaf buds pointing out on the 12th, while the
