An examination October 4th and 5th revealed much injury from 

 the bordeaux mixture, many of the apples checking and codling 

 moth larvae of the second brood entering at such points. An 

 effort was made to approximate this injury and small, random 

 samples from various trees were carefully sorted. The results 

 are tabulated as follows :

We endeavored, in the above table, to put in the smooth class 

 only those apples which were at least fairly smooth. A large pro- 

 portion of those classed as injured were not seriously affected, 

 aside from appearance, though some were badly gnarled and even 

 cracked. It will be seen at once that a very high percentage of the 

 fruit en all the sprayed trees were more or less rusted, while the 

 proportions are approximately reversed on the unsprayed trees. 

 Burning by bordeaux mixture was strikingly illustrated in Mr 

 Shons' Ben Davis, some 90 to 95 and possibly 99 per cent of the 

 apples being badly rusted and in some cases so seriously affected 

 (pi. 13) that portions of the apple were irregular and more or less 

 covered with rounded, tuberclelike elevations. 



A considerable number of apples had been entered at the stem. 

 The Tortricid larva, mentioned above, was still working on the 

 apples in some numbers, either under a leaf, on the side of the fruit 

 or beneath a light web at the blossom end. A note made by Mr 

 Young September 13th records that over 90 of the 115 clean apples 

 dropped from tree E, plot 3, had been gnawed by some larvae, prob- 

 ably that of this Tortricid. The work of this insect is illustrated 

 on plates 10 and 11. A' tabulation of the data obtained upon these 

 plots follows.
