EXPERIMENT STATION REPORT. 623 



scales were found only at the base of the new shoots. The infes- 

 tation is certainly no' worse than in 1903, and it is remarkable 

 that the history of slow summer development is almost identi- 

 cally the same for tlie two years. 



Trkk 34 — Lawrence Peer. March Qlh, the tree was mod- 

 erately infested en the trunk, less so oil the lyranchos, and was 

 sprayed with caustic soda solution, i}4 pounds in 2 gallons of 

 water. Leaf buds were pointing' out April 26th, blossom buds 

 began tO' open May 7th; all the flowers were open May nth, 

 and some petals were already dropping. Only one fruit set, and 

 that held on for a few days only. June 27th, only a few live 

 scales were found, and most of these ^vere new sets. These 

 increased in number, so that, on July 13th, sprayed with Rose- 

 leaf tobaccO' extract, i pound in 5 gallons oi water. This was 

 (]uite effective, and devek)]>ment later in the season was so slow 

 that not until October i8th was it deemed deSiraJDle to^ treat. 

 Sprayed, October 19th, with Kill-O-Scale, i part to- water 20 

 parts. On the 25th few living insects were noted, some (jf the 

 leaves were spotted, but that did not seem to- be due to- the 

 spraying. No'vember 2d, most of the foliag'e was oiff, and what 

 remained was discolored. There was a scattering oi scale on 

 the tree, very little on the new wood, and not mucli anywhere. 

 That which is onl the old wood is dead. 



Tree 35 — Japanese Wabmt. April 26th, terminal liuds began 

 to unfold ; May 7th, blossom clusters well advanced. June 27th, 

 when the scale examination was made, there was quite a scat- 

 tering of half-grown black scales; but, on examination, every 

 example was dead. No lar\ce or recent sets were noted at any 

 time during the season. November 2d, all the foliage was gone; 

 the tree had made its usual good gro'wth, and had matured a 

 small crop of good-for-nothing nuts. There was tlie usual scat- 

 tering of half-grown black scales, and, also- as usual, few of 

 them showed any live creature beneath. 



Tree 36 — Redmond's Pavorite Peach. Set Octol^er 27th, to 

 replace an apple. Did not pass the winter well, and showed 

 some dead wood below the pruning. Made an irregular start 

 May 17th. and, on June i8th, I decided that I could not get a 

 satisfactory tree out of it. On that day, drenched with caustic 

 soda solution, i pound in 7 gallons of water. June iQth, foliage 

 and shoots were black spotted, and some oi both leaves and tips 

 were entirelv killed. June 28th, there had been no' recovery. 

 The foliage was pitifully burnt, and there had been no effort to 

 start from the dormant buds on the old wood. August T8th,
