The first column gives the total numbers of samples of each variety

 edibility. 



lua general way. these results indicate thai the standard of 17 degrees 

 Balling is about right. The lower degree at which the Sultanina was 

 accepted may be due to the fact thai this variety was the earliest. Hot 

 weather makes a higher acidity acceptable and the novelty of the first 

 grapes makes the judges less critical. 



Converse reasons may accounl for the higher sugar required for the 

 Tokay. 



There is nothing to indicate the advisability of a lower standard for 

 Emperor, but rather a higher, at least in the Balling acid ratio.

 (Vineyard and Packing House Samples, 1914-'15-'16.) 



Table II includes data on a larger number of samples and varieties 

 than Table I. It includes a number of varieties in the Kearney, Davis, 

 and Imperial collections not included in Table I. The results, however, 

 are confirmatory of those of Tabic II, which include only the usual 

 varieties and packing bouse samples.
