were noted, showing continuous breeding on tlie tree, no fiu'ther 

 insecticide applications were deemed necessary. 



November 2d, most of the foliage w^as off ; the tree w-as quite 

 scaly, and a specimen of the twice-stabbed lady bird (Cliilocorus 

 biviilncrus) was noted feeding" upon the insects. The tree is 

 bad enough for winter treatment. 



Tree ^2 — Mountain Rose Peach. Set October 27th, 1903, to 

 replace a Lawrence Pear taken out. Made no real start until 

 well along in May, and then developed irregularly. There were 

 no scales found June 27th, but on August i8th, all stages from 

 larva to adult occurred, and these developed until it was deemed 

 necessary to^ spray, October 20th, with Kill-O-Scale, i part to 

 water 20 parts. This cleaned out things pretty well, and caused 

 a little burning of the leaves. 



November 2d, the foliage was about all ott and what remained 

 was spotted by the oil. The buds, however, were unharmed, 

 and such scales as were examined were dead. 



Tree 2>3 — Dwarf Ditchessc Pear. March 9th. received an 

 application of caustic soda solution, 1J/4 pounds in 2 gallons of 

 water, and needed it. 



Buds began to swell April 17th, but no start was made until 

 die 26th ; first blossoms opened IMay 5th : was in almost full bloom 

 May 7th; petals began to drop May nth, and was out of bloom 

 May 17th. Had set a fair crop May 27th, but some of the fruits 

 had been already eaten out, probably by Alay beetles, and, June 

 8th, only two fruits remained. These, however, came to maturity 

 in good shape. 



June 1 8th, one of the branches was sprayed with the caustic 

 soda solution, i pound in 8 gallons of water, to test the effect 

 on the foliage. Next day both leaves and fruit were black 

 spotted, but there had been no- bad eft'ect on the shoots. It sim- 

 ply gave the tree a ragged appearance. 



June 27th, there were only a few recent sets, no moving lan^je, 

 and it was not deemed necessary tO' spray. Development was 

 slow for some reason, and, although moving larvse and white 

 sets were rqx)rted at each examination, there was nothing to 

 demand attention until October 14th. when the tree ^^•as sprayed 

 with Kill-O-Scale, i part to water 20 parts. On the 20th, there 

 was a mere trace of injury to the foliage, while only 0. few living 

 scales could be found. November 2d, the foliage 'vas all off, 

 the tree had made several \'ery long shoots from the top, and had 

 some of the original lower branches, so- that it is now neither 

 dwarf nor standard, and has little, if any, bearing wood. Live
