TiiEE 19 — Vermont Beauty Pear. In a general way this has the 

 same history as No. 18, but was never quite so badly infested. It was 

 sprayed March 6th with Napthol-Sulphur, one to thirty-two, the 

 application being thorough enough to discolor the snow from the 

 drippings. There was no appreciable effect from this, and during the 

 summer the arsenate of lead and soap mixtures were applied as for 

 No. 18, and with no greater effect. 



August 21st, sprayed with kerosene and resin, one part to water 

 fifteen parts, and made thorough work of it. An attempt was made 

 to hit all the foliage from the outside. The fruits were especially 

 aimed at, and most of the branches were sprayed from below. Some 

 injury developed, but not very much, and the fruits were taken off on 

 the 26th so infested as to be useless. August 31st, applied kerosene- 

 resin emulsion No. 3 at the rate of one to thirty, so thoroughly as to 

 run down the trunk in a stream. The mixture was irregular, and 

 some of it seemed to carry much more resin than others. September 

 13th, there was quite a bit of burned foliage and some had dropped. 

 The scale situation was not so bad as it had been and some benefit had 

 been derived from the spray. 



October 24th, applied "Scalecide," one part to water twenty parts, 

 and covered pretty thoroughly. The tree was not quite so bare as No. 

 18, but almost as bad in condition. 



Teee 20 — Meech Quince. Sprayed March 6th with Napthol-Sul- 

 phur, one part to water thirty-two parts. 



April 12th, leaf buds were starting; on the 30th, was practically 

 in full leaf; May 11th, first blossoms were open; on the 14th, was in 

 full bloom, and on the 26th, all the blossoms had dropped. Only a 

 small crop set, but the tree did well otherwise, except that by July 16th 

 it had more scale than ever before in its history. On the 22d, drenched 

 with whale-oil soap, one pound in six gallons of water. At this time 

 the dry weather had stopped all growth except in the developing fruit. 

 After conditions improved fresh growth started, and on August 19th 

 the tree looked very well, though there was a heavy crop of larval 

 scales on the move. 



August 21st, sprayed with a kerosene-resin mixture, one part in 

 fifteen parts water, and soaked all parts of the tree. On the 22d the 

 wood looked as if it had been varnished, some of the foliage was dis- 

 colored and the young and recent sets seemed to have been wiped out. 

 Injury intensified and extended to the fruit, crippling some that re-
