in g"CK)cl general condition; but very scaly. Most of this scale 

 was dead, and scraped oft' readily as a dry scruf ; even, in those 

 places that first .became infested during the past summer. There 

 were living scales, however, especially at the bases of twigs. 

 The remnant of oil was obvious on the surface of the tree, but 

 there was no appearance of any bad effect on the development 

 of the fruit buds. 



Tree 29 — Civ:i'ciisfciii Apflc. March 10th, sprayed thor- 

 oughly with the "Universal Insecticide and Scale Killer." The 

 tree was not very badly infested, and did not really need the 

 application, l)ut there was scale enough to test the effect of the 

 spray. 



Some of the terminal leaf buds began unfolding April 26th; 

 was leafing out fully May 7th, and, on May nth, had three 

 blossom clusters well up in the tree, which set no fruit. 



June J7th, the scale situation was in so far satisfactory as 

 there were only a few breeding adults, and there had been no 

 great number of recent sets. July 13th, though there was only 

 a thin scattering of white sets, it was deemed desirable to test the 

 effect of the Roselcaf tobacco extract, and the tree was sprayed 

 W'ith it, at the rate of i pound of the extract in 5 gallons of water. 

 The application did not harm the foliage, and wdiile it undoubt- 

 edly killed some scale, left matters, on the 29th of July, just 

 about as they were Ijefore the application was made. But for 

 some reason things did not become worse; and, on November 

 2, there was merely a scattering of scale, massed only at a few 

 points at the bases of twigs. At that time, the tree was in fine 

 general condition, tlie foliage about half off, and everything 

 pointing to a crop for 1905. Sexed forms of the apple-plant 

 louse occurred in some numbers, but as yet there were no eggs. 



Tree 30 — Grimes' Golden Pippin. On March loth, gave this 

 tree a very thorough spraying with the Universal Insecticide and 

 Scale Killer. It was quite thoroughly infested, and needed the 

 application. 



Leaf buds began opening about May ist, and. on the 7th, 

 some of those in the upper part had not opened yet. At that 

 time the blossoms were showing pink. Init none were open ; on 

 the nth, there was a mass of bloom. Petals began to drop 

 May 17th, when some buds had not yet opened, anl not until 

 after the 20th was the tree entirely out of bloom. May 27th. 

 the set was lieavy, and it continued to develop until after the 

 middle of June, whfn most of the fruits in th^ iVpper part were
