and ran west, the trees in the rows being numbered from the road 

 northward. 



Plot 1 began on row g with the third apple tree north from the 

 road, and on row 10 with the second apple tree north, these being 

 trees i and 3, respectively, while trees 2, 4, 5 and 6 were the third, 

 fourth and sixth apple trees, respectively, on the ninth row. 



Plot 2, trees 1 and 5 were the sixth and seventh apple trees, respec- 

 tively, north from the road on row 10, and trees 2,3,4 and 6 were 

 the eighth, ninth, tenth and eleventh apple trees, respectively, north 

 from the road on row 9. 



Plot 3, trees 1, 3 and 5 were the third, fourth and fifth apple 

 trees, respectively, north from the road on row 15, while trees 2, 4 

 and 6 were the third, fourth and fifth apple trees, respectively, north 

 from the road on row 14. 



The check tree was the seventh apple tree north from the road 

 in row 15. North of the check tree were a series of greenings. 



The first spraying was begun June 1st. Thompsen's BT dry 

 soda-sulphur was used at the rate of 3 pounds to 50 gallons of water, 

 and 4 pounds of Niagara arsenate of lead was added. The blossoms 

 were mostly off, fully 98 per cent having dropped. One man sprayed 

 all the trees from the top of the tank, the tops being hit only by 

 drift in the case of the larger trees. The application was fairly 

 thorough though there probably was a little missed here and there. 

 At 12 o'clock all the plots had been sprayed except the southern 

 six apple trees on row 9, and these Mr Curtis finished up early in 

 the afternoon. The day was ideal, bright and sunny and with only 

 a light breeze. Mr Curtis stated that the orchard had been sprayed 

 for years and that he had experienced comparatively little trouble 

 from side- worm injury. 



The second spraying began about 9.30 June 2 2d and was completed 

 at 10.40. Thompsen's paste arsenate of lead was used at the rate 

 of 3 pounds to 50 gallons of water and Thompsen's lime-sulphur 

 wash at the rate of 1 to 45. At this time some burning of the leaves 

 was evident, though in most cases the damage was not serious. 

 Mr Curtis stated that in each instance this had followed an applica- 

 tion June 5 th or 6th, made only a few days after the exceptionally 

 heavy rains of June 1st and 2d. The Baldwins at this time had a 

 diameter of one-half to three-fourths of an inch and showed a marked 

 fuzziness. There was abundant fruit on the check tree and con- 

 siderable fungus though the foliage was not in markedly poorer 

 condition than that on plot 3. Mr Curtis stated that tree 3 of plot- 

 3 was sprayed from the east side after June 1st by mistake and the
