pear on the 26th. First blossoms open May 7th, in full bloom 

 May loth, petals began to drop on the nth and on the 17th the 

 tree was entirely out of bloom. May 27th there was a scant set 

 of fruit compai^ed with, the amount of bloom. 



June 27th the tree looked sick; some of the branches were 

 dying at the tips and the foliage was not vigorous in appearance. 

 Cut out the dead and dying wood. Very little fruit left and most 

 of that was stung by the Curculio. There was scale throughout 

 the tree, more on the branches than on the trunk and some parts 

 pretty well covered. There were a few crawling larvae, quite a 

 number of recent sets and a large number of females with groups 

 of larvae beneath the scale. The winter application had been com- 

 pletely ineffective. 



June 30th sprayed with Pyrol tree and plant spray i part to 

 water 40 parts; covering thoroughly from the house side, but 

 leaving the fence side unsprayed. Some injury to foliage de- 

 veloped and early in July quite a number of leaves toward the 

 center of the tree appeared to be badly burned. At the same time 

 there were live scales in plenty and especially toward the house 

 there was a pretty coating, with crawling larvae and new sets 

 pretty well scattered. 



July 8th sprayed with the horticultural compound 2 ounces in 

 I gallon of water, covering thoroughly from all sides. This 

 seemed to have a rather good efifect for larvae and recent sets be- 

 came much less plentiful and continued so until after the middle 

 of August when there was again so general a movement and 

 setting on the tree that it was resprayed, August 19th, with the 

 same compound at the same strength as before. Rain came almost 

 immediately and very little effect was noted on the 25th ; so, on 

 August 29th, another similar application was made. This seemed 

 to kill off the moving larvae and some of the recent sets, but in a 

 few davs matters seemed about as bad as ever. The tree was left 

 to itself however, becoming ever more infested until October 15th 

 wh.en it was sprayed with Kill-O-Scale, at the rate of i part to 20 

 of water. 



October 20th, very few live adults were found on the tree. All 

 the larvae and white sets and nearly all the black sets were dead. 

 There was a very slight burning of the leaves and the tree looked 

 and smelt about like those treated with the soluble petroleum. 



November 2n(l, the foliage was about half gone; what remained 

 was somewhat spotted and traces of the oil were everywhere vis- 

 ible on the trunks and branches. There were no larvae and no 

 recent sets and wherever examinations were made the insects
