when a second application of the horticultural compound was 

 made. Two days later there were fewer larvae and white sets 

 than before, but yet a plenty of living insects. September i6th, 

 sprayed thoroughly \\'ith a mixture of equal parts of soluble 

 petroleum and water. On the 19th, most of the adults were 

 dead, but there were yet some white sets and recenlly hatched 

 larvae. The bark had a dark greasy appearance, the leaves were 

 more or less glossy, and some had turned black. On the 29th. 

 the number of lan'cie, recent sets and living insects had decreased. 

 October 15th, the condition had improved yet further, but there 

 were still many live, older sets. November 2d, the foliage was 

 all off, and, apparently, there was a heavy set of fruit spurs. 

 The tree is vei^ scaly, and much of the sap wood is purple. 

 Many of the small twigs are dead. There were no larv.ne. no 

 recent sets, and most of the black sets were dead ; but there 

 were yet some living examples at almost every joint. 



During the month of September a very satisfactory crop of 

 pears was secured from this tree. Some of the more highly 

 colored outside fruits were removed before they were quite ripe, 

 but they mellowed nicely indoors and made good eating. 



Tree 20 — Meecli Quince. Leaf buds began opening April

 the tree was in good healthy condition, with a scattering of live 

 scales, a few crawling larvae, and a few white sets. Although 

 the infestation w'as very slight, sprayed with the horticultural 

 compound, 2 ounces in i g-allon of water, on July 8th, when sur- 

 rounding trees were treated. The spraying made little or no 

 difference in the condition of afifairs, and all stages continued 

 to be found in small numbers throughout the season. 



It made and ripened during October a very decent little set 

 of fruit, and on Nove,mlj€r ,2<l was }'et in almost full foliage. 

 It had at that time more scale than at any previous period in its 

 history, yet it was not a bad infestation. There were no larv?e 

 and no' living recent sets, but the half-grown black scales were 

 generally alive, and they were grouped chiefly at the branchings. 



Tree 21 — Vermont Beauty Pear. April 5th, s]>rayed very
