Jonathan is the onby variety free from Pit, and this is irrespective of the stocks. 



The highest percentage of Pit was found in Baldwin, and the next highest was Shockley. 



It is rather a striking result that in every instance the varieties on Northern Spy roots alone, 

 without any intermediate stock, were the worst affected. Cleopatra on Spy also gave the highest 

 yield, 149 Ibs. 



The Cleopatra trees marked (Q) are special. The scions from which these trees were worked were 

 obtained from an old stunted tree in Mr. Qninn's private garden, the fruit of which, up to the time of 

 working the test trees, had not been known to have had Pit. Afterwards, however, when stimulated 

 by tillage and water, it produced larger-grade apples, very much affected by Bitter Pit.
