Not until August 19th was any living scale seen, and then a very 

 slight scattering became apparent, as though from a new infestation 

 or a few survivors. Up to October 1st the specimens were not numer- 

 ous enough to be obvious and the tree was then still in good foliage. 



August 22d, spra3'ed with arsenate of lead, one pound in nine gal- 

 lons of water, to test the quality of the insecticide, and no injury 

 of any kind developed on the foliage. 



October 24th, foliage yet in good shape and fruit buds developing 

 well; sprayed with "Scalecide," one part in twenty parts of water, 

 and covered fairly well. On the 30th the application was repeated 

 more thoroughly, though the foliage still held on well. 



Tree 24 — Greenshoro Peach. Started early in April, leaf buds 

 opening out on the 12th, some flowers open on the 2Tth, while on the 

 30th the tree was in full bloom. ^lay 7th was almost, and on the 

 11th altogether, out of bloom and leafing out well. May 26th, a good 

 set of fruit had. been. made and a little leaf-curl developed, which 

 remained obvious until the early days of June. 



The "June drop" was heavy, but enough fruit to tax the tree re- 

 mained and developed gradually, so as to furnish pickings from 

 July 25th to August 5th, when it was all off. 



This is another of the shaded trees, and no scale-breeding was 

 observed until late June, but in July a brood was on the move, so 

 heavy as to demand immediate attention. 



July 5th, sprayed thoroughly with "Anti-Scale," a petroleum 

 preparation, at the rate of one part to thirty of water. Severe injury 

 to foliage became apparent July 9th, some leaves being badly spotted^ 

 others turning yellow and dropping. It was questioned, however,, 

 whether the dry weather was not, in part, responsible for this pre- 

 mature falling. Early in August the yellow spotting on the foliage 

 disappeared, leaving small, irregular holes in its place. August 19th, 

 so heavy a second brood was on the move that it was deemed wise to 

 spray on the 21st with a kerosene-resin mixture, one part to ten parts 

 of water. As the foliage was thin it was possible to reach most of the 

 branches without hitting the foliage very much, but enough was ap- 

 plied to test its effect. On the 22d the leaves had more holes than 

 before, but otherwise were not Imrt. On the 26th injury had not 

 intensified, but there was another brood of larvae on the move, and I 

 sprayed with emulsion No. 3, kerosene-resin, at the rate of one part 

 to forty of water, on one branch only, to test its effect. August 27thy
