6o8 NEW JERSEY STATE AGRICULTURAL. 



this season. Some of the leaves had turned brown and a few had 

 dropped, but there was no serious injury to the foHage. 



October i6th, tliere were a few live adults, quite a few white 

 scales and an occasional larva. Quite a number of living speci- 

 mens were amoiig the older sets, though most of them were dead. 



November 2d, the foliage was nearly all off. There had been 

 some recent breeding, but none seemed tO' have gotten beyond the 

 white stage, though some of the older black scales were un- 

 doubtedly alive. The infestation extended to the tips of the 

 shoots, but was not bad. On the old wood, where the infesta- 

 tion was heaviest, the scale seemed to be dead. Traces of the 

 oil were yet obvious, and without doubt the last application was 

 an effective one. 



Sexed forms of the apple louse were found on the 1 cw remain- 

 ing leaves, but apparently egg-Jaying had not begun at all 

 seriously. 



Tree 3 — Black Tartarian Cherry. Leaf buds were ready to 

 open April 17th; the first blossoms opened May 3d, was in full 

 bloom May 7th, and out of bloom on the nth. Made a fair 

 set of fruit, which reached that stage of ripeness at which it was 

 attractive tO' boys and birds June 15th. To avoid trouble, as 

 the family was about to leave, all the fruit was taken off. The 

 tree made its usual good growth during the season, and Novem- 

 ber 2i\ was yet in almost full foliage. No scale at any time, 

 and no treatments of any kind. 



Tree 4 — Divarf Pear. This tree had been grown foi* the 

 trellis in Europe, remained one season in a New Jersey nurser}-, 

 where it became moderately infested with scale and was set here 

 October 28th, 1903. 



March 9th, 1904, sprayed with caustic soda. 1I4 pounds in 2 

 gallons of water, and drenched thoroughly. 



Not until May 17th was there any sign of startin^^-, and then 

 from- buds far down on the trunk. On the 27th all of last year's 

 wood was dead and dry, and, June 8th, it was cut off 18 inches 

 alDO've ground, tO' which point the live wood extended. No scale 

 was noticed during the early summer; but on August i8th there 

 were a few adults, a few recent sets, and a few crawling larvae. 

 It did not become much better as to growth, nor worse as to 

 scale, during the remainder of the season, and was ordered cut 

 out November 2d. 



Tree 5. — Removed in 1903, and not replaced. 



Tree 6 — Grcenshorough Peach. March 9th, this tree, being 

 ver\' scaly, received a thorough drenching with the solution of
