as well as of those sprayed, and here the relatively low percentage 

 of wormy fruit is undoubtedly due in part to the fact that the check 

 trees of 19 16 had been sprayed in 191 5 as thoroughly or nearly as 

 thoroughly as the experimental trees. Too much importance should 

 not be attached to this, since the entire orchard had been sprayed 

 for several years before and the probabilities are that the codling 

 moth infestation in this orchard the past season was not so serious 

 as in 19 1 5. The comparison between the two years is, on its face, 

 most gratifying and a portion of the gain at least can be legitimately 

 ascribed to the thorough work of the preceding year ; if this is the 

 case a further improvement should be noted next season. 



The close relation existing between the reduction in the percentage 

 of wormy apples and the percentage showing the " side July " type 

 of injury (this latter including the " side July " and the " shallow " 

 of the 19 16 classification) is shown by the fact that the ratio between 

 the percentage of wormy of 191 5 and " side July " of that year is 

 very nearly the same as the ratio existing between the wormy for 

 19 16 and the " side July " of 19 16. This is true not only of plot 1 

 but also of plots 2 and 3 and the check trees. Furthermore, a similar 

 ratio between the percentage of wormy of 19 16 for plots 1 and 2 is 

 very nearly the same as the ratio existing between the " side July " 

 affected fruit for the same year, and this also holds with remarkable 

 closeness between plots 2 and 3. These relationships are another 

 indication that the reduction in the " side July " wormy fruit closely 

 parallels that of the total wormy. 



Albion Orchard 



This is a fine king orchard about 2 \ miles northeast of Albion 

 and belonging to Mr A. G. Snyder. These trees are about 40 years 

 old, set 40 feet apart and are in a good, thrifty condition. 



Three plots and one check tree were selected as follows: 



Plot 1 consists of trees 1 and 2 north from the southern boundary 

 of the orchard and trees 1, 2 and 3 west from the eastern boundary 

 or adjacent highway. 



Plot 2 consists of trees 4 and 5 north and trees 1, 2 and 3 west. 



Plot 3 consists of trees 8 and 9 north and 1, 2 and 3 west, except 

 that tree C in row 9 was replaced by a tree in row 10 directly north, 

 of tree A. 



The check tree was 5 trees west, and 1 tree north from the 

 southeastern corner, there being a vacancy in this row where tree 4 

 should stand.
