Mr 



fruit cannot be explained by the practice of "half" packing 

 He continues :— " I agree . . • . . that it " [the disease] " is 

 ot purely physiological nature. At one time I held the opinion 

 that it might be due to the widespread use of 'Northern Spy' 

 stocks, as this apple is itself the most subject of all to the trouble, 

 also the wood is given to « canker ' in some instances. This also 

 is a fallacy, as I have found ' Bitter Pit ' on trees grafted on 

 French Crab' and other stocks, but in no instance, so far, on 

 seedlings. Our natural varieties which reproduce themselves 

 truly are all immune." 



If, as Mr. Davis explains, « Bitter Pit ' is not confined to South 

 Africa, and if, as was stated when apples so affected were first sent 

 to Kew for examination, this disease destroys the commercial 

 value of the fruit, it is to be anticipated that its study will be 

 undertaken by workers in other apple-producing countries. For 

 the information of all who are, or are likely to become, interested 

 in the subject, it seems advisable to make available without delay 

 the observations recorded by Mr. Davis.
