drenched with Kerosene-Xapthol, one to ten parts of water, March 

 6th, 1905. Did not start until April 12th, and was moving slowly on 

 the 30th. Was in full hut scant bloom May 7th, and made a small 

 set on the 14th. May 19th, sprayed with arsenate of lead, one pound 

 to twenty gallons of water, and repeated the application ten days 

 later, at the rate of one pound to fifteen gallons. 



The fruit developed normally and up to the middle of August there 

 was practically no scale on the tree. On the 19th of that month a 

 few fruits showed a trace of recent sets on the side nearest to 31, and 

 there was the merest indication of codling moth. 



August 26th, all the fruit was removed, and in view of the fact 

 that this tree was at one time very badly infested, and has had ap- 

 plications of about everything that was ever used, from tobacco to 

 crude petroleum, it will be interesting to note its condition, premising 

 that owing to its premature removal it was undersized. In all there 

 were 109 apples, of which ninety-one were absolutely clean and 

 eighteen showed scales or scale marks. t)f the infested specimens 

 seven had one scale only, or a scale mark counted as a scale; six had 

 two scales; three had a sprinkling of small scales, and two had three 

 or more scales of the first brood. Besides this there were two fruits 

 excluded from consideration because they had codling moth — the only 

 wormy apples on the tree. Irrespective of scales, fifty-six of the 

 apples were perfect, thirteen were slightly marred by outgrown 

 curculio punctures, and the remainder were seconds, most of them 

 getting their rank because of curculio marks and spots. 



The balance of the season seemed to give added vigor and color to 

 the tree, and on October 24th it was yet in perfect foliage, the leaves 

 of a rich green color and the picture of vigor. Sprayed with "Scale- 

 cide," one to water twent}^ parts, as thoroughly as the mass of foliage 

 would allow. 



In view of the past history of this tree its present condition is 

 remarkable and seems to indicate that so long as there is a sound 

 stock and plenty of food the scale can be practically eliminated. 



Tree 31 — German Prune. Sprayed with Napthol-Sulphur, one 

 part to water thirty-two parts. Made a start early in April, buds 

 beginning to show green on the 12th, while flowers opened on the 30th. 

 Was out of bloom and in full leaf May 11th, and made a good set of 

 fruit. The curculio began to get in its work about the middle of 

 June, and early in July fruit began to drop as the result of the attack.
