June, 1911.] FRUIT BUD FORMATION. 11 



No attempt should be made to draw any conclusions from the results of the 

 work in 1909 owing, first, to the light crop which prevailed through all plots, 

 and second, to the fact that the treatments of the various plots had not been 

 long enough in progress to produce noticeable effects on the formation of 

 fruit buds. 



REPORT OF PROGRESS IN 1910. 



As in 1909, the first operation performed consisted in pruning all the trees 

 in the orchard. This was following by a spraying with lime-suphur wash 

 applied before the buds started into growth in the spring. The formula 

 used was composed of 15 lbs. of lime and 15 lbs. sulphur to 50 gals, of 

 water. The mixture was cooked by steam derived from the college heating 

 plant. Later operations consisted in spraying with arsenate of lead paste, 

 3 lbs. to 50 gals, of water, immediately after the blossoms fell. A similar 

 application was made two weeks later, and a third application was given the 

 first week in August. The orchard was sprayed again during the second week 

 in August with kerosene emulsion for apple leaf-hoppers. As in 1909, the 

 spraying seemed to destroy large numbers of the insect, but was not effective in 

 eradicating it. With the exception of this insect all other pests were thor- 

 oughly controlled, and so completely was the codling moth eradicated that 

 not a single wormy apple was discovered in the orchard. 



All operations in connection with the applications of fertilizers and the cul- 

 tivation of the plots were carried out according to schedule. 



The records made during the year include an estimate of the number of 

 blossoms produced by each tree, an exact record of the number and grades of 

 fruit, a diary of all work performed in the orchard, and a record of twig growth 

 for the season of 1909. 



The inclusion of the blossom estimate was an innovation of 1910. Such a 

 record was considered desirable in view of the fact that accidents of storm, 

 insect attack, or disease might later reduce the crop and vitiate a year's results. 

 The record was made with the greatest care. A standard tree, apparently as 

 full of blossoms as a tree could possibly be, was graded 100. Each tree in the 

 orchard was given a percentage grading as compared with the standard tree. 

 Three separate records were made at daily intervals in the height of the 

 blooming season, and the average of the three gradings was recorded. 



The records show that there were produced in the orchard on all trees 

 which were included in the plots and division rows 401,660 apples. In addi- 

 tion to thes'e, some 50 trees were discarded and their fruits, though recorded, 

 are not included in this total; 500 barrels were marketed, and in addition to 

 these a large number of apples, blown off in a wind storm just as the picking 

 season began, were sold for cider. 



Yield of the Orchard Plot by Plot. 



The ensuing tables, Nos. 4 to 14, give the yields of each plot tree by tree. 

 From each plot have been deducted certain individual trees, the productions 

 of which were far out of the range of productions of the other trees in the
