There is a very noticeable difiference in the percentage of good 

 fruits on adjacent trees when treated in the same manner. But 

 trees sprayed three or four times are more uniformly good than 

 those sprayed once or twice. As seen in the table, in the row 

 sprayed once, there is a difference of more than 32 per cent, in 

 the amount of fruit on the second tree, and that on the trees on 

 either side — a difference frequently noted on the unsprayed rows. 

 In the rows treated twice this difference is not quite so marked ; 

 while in the rows sprayed three or four times the greatest differ- 

 ence is only about 14 per cent., the lowest percentage being nearly 

 equal to the highest on the trees sprayed but once. 



By comparing the last division of the table with the third, it 

 will be observed though each row was sprayed three times the 

 average quality of the fruit is much lower in the former case, 

 the average per cent, of No. 1 fruit being 56.3, as opposed to 

 77.2 in the third row. That is, the indications point strongly to 

 the value of spraying early. The two rows in question were under 

 essentially the same conditions, being parallel and separated by 

 only one row, which was sprayed four times, but the first was 

 sprayed once before the blossoms opened, while the other was not 

 sprayed till June 23. 



The results obtained are not conclusive, but in general they 

 point to the value of repeated applications and to the desirability 

 of spraying early in the season. 



Results in Mr. Moore's Orchard. 

 To check our work still further, arrangements were made with 

 Mr. C. E. Moore of Winthrop to continue the work of the pre- 

 vious year in this direction. Mr. Moore's orchard is usually ver}' 

 badly attacked, and would seem to be an excellent field for work. 

 The trees bore ver}' heavily in 1891, however, and were not as 

 well adapted for our use as they otherwise would have been. 

 Those trees which bore but little fruit are not considered in com- 

 piling the tables, as such trees are seldom attacked so severely as 

 are those which bear a full crop. As will be observed, the character 

 of the fruit on the different trees is very unequal ; that on some 

 trees being either excessivel}' scabby or remarkably free from scab, 

 while that on other adjacent trees may represent the opposite 

 extreme. Thus it follows that the average percentages as given in 

 the tables do not always represent the true average condition of 

 the trees, especially is this the case when a larger number than 

 common is taken from any one tree. As before noted, however.
