These trees were sprayed five times the two sections are very distinct. An infection of per cent occurred in tlie tops of tfie trees in tliis block, while the lower fruits possessed per cent scab. Total average infection in this block was ; where five sprays were used (Block 3) it was per cent. The possibilities of using the four- spray schedule will be briefly discussed later in the article. Relation of Fruit Production to Scab Infection In connection with the percentages determined in Block .\, it is interest- ing to take into consideration the sig- nificance of the relative bearing areas of the trees as shown in Figure 1, and their relation to scab infection as found in different parts of the trees. The average production of fruit in these areas does not vary greatly. This distribution was as follows: Ground to ten feet, per cent; from ten to fifteen feet, per cent; from fifteen feet to the tops of the trees, per cent. As would be expected, owing to the fact that trees of this size reach their greatest diameter between ten and fifteen feet, a larger amount of fruit would be found in this section of the tree than elsewhere. The quality of the fruit produced in this section is average of the entire tree. As a rule, however, the larger, physically finer, and more highly-colored apples are produced well toward the tops of the trees, while the lower fruits are usu- ally smaller and subject to more in- juries, especially those caused by the brown aphis.
