spraying, October 24:th, was done more thoronghly than on No. 15, 

 because it was better possible to get around it. 



Tree 17 — Trellised Peach. This received an application of "Kill- 

 0-Scale'- October 14th, 1904; began to start slowly and irregularly 

 early in April, and on the 21st some blossom buds were ready to open. 

 Some did open on the 23d, and the tree was in full, if scant, bloom on 

 the 2Tth. Only one fruit set, and on June 25th, when half grown, 

 began to rot and was taken off. It is smooth-skinned and more like a 

 })lum in texture, though obviously a peach in other respects. 



Growth was irregular and one branch died, but the other sent out 

 long, vigorous shoots, so that at the end of the summer it seemed pos- 

 si))le to get it into usable shape as a dwarf. Plant lice attack became 

 obvious May 25th, and soon after leaf curl developed. The latter per- 

 sisted until late in June, after the lice had disappeared. 



]\Iay 25th, sprayed the infested tips with soluble petroleum, one 

 part in thirty parts of water. June 2d, there was no appearance of 

 injury from the oil, nor, on the other hand, did the plant lice show 

 much if any effect : the mixture was too dilute to do either good or 

 harm. 



No scales were seen until July 9th, when there was a slight trace 

 that may have come on from the outside, since there were only single 

 small specimens on the new shoots. October 24th, there was still only 

 a scattering, but all over the tree, and enough to provide for a good 

 infestation next year. Foliage still perfect at that time and "Scale- 

 cide" was thoroughly applied at the rate of one part in twenty of 

 water. 



October 30th, received a second application of '''Scalecide," at same 

 strength; foliage still perfect. 



Tree 18 — Vermont Beauty Pear. Started early in April, and on 

 the 12th leaf buds were well advanced and blossom clusters beginning 

 to separate. A few blossoms opened April 27th ; on the 30th more than 

 half of them were out, and on May 7th the tree was already beginning 

 to go out of bloom. The set of fruit was small, owing to adverse 

 weather conditions, and on May 26th it was noted that a large per- 

 centage of it was infested by the pear midge. This was quite un- 

 expected, as its almost total absence last year led me to believe that it 

 had worked itself out. 



June 25th, only a small set of fruit remained, and on this scale 

 larvae were rapidly setting, there being a full brood in evidence. July 

 8th, sprayed thoroughly with fish-oil soap, one pound in four gallons
