 1907-08. 



In 1905 the Northern Spy was said to be very bad, Wolsey bad, and 

 Reinette du Canada slight. 



A glance at the above table will show that although some varieties 

 are undoubtedly worse than others, for example, Northern Spy, D. T. 

 Fiske, Wolsey, and Versfeld, yet other varieties, such as Adam's Birthday 

 and Cornish GiUiflower, which were very badly afiected in 1904, were 

 reported clean in 1907, or only slightly affected. 



Mr. Dicey has also been good enough to supply me with the following 

 estimate as to the percentage of apples affected by bitter-pit within the 

 last three years : — 



In 1906 between 40-50 per cent, were affected. 

 In 1907 between 40-50 per cent, were affected. 

 In 1908 between 5-10 per cent, were affected. 



Speaking of the small percentage of infections in 1908, Mr. Dicey 

 says : "I think that I have already informed you that last year we had 

 an exceptionally heavy crop of apples, heavier than we have ever known 

 it before, and the presence of so Uttle bitter-pit would seem to confirm 

 your theory as to the cause, there being sufficient scope for the sap in the 

 unusually large crop without bursting any of the cells." 



The general experience throughout South Africa so far as my observa- 

 tion and information go is that the large sappy varieties which ripen quickly 

 are especially liable to bitter-pit, whereas the smaller and firmer fieshed 

 varieties are not so subject to it. 



I have only met with two varieties of apples which can witii any 

 degree of accuracy be regarded as immune to the spotting. They are 

 both of local origin, they have originated as Cape seedUngs, and have been 

 grown in the country for years. They are known locally as the Koo and 

 Wemmers Hoek, they are usually grown on their own stocks, and are 

 propagated by means of rianners or in-lay ers.
