But these changes in ash composition are found to be 
directly associated with an increase of sugar, a decrease of 
free acid and a general improvement in the quality of the 
berry. 
Turning now to the wild grape, we find at the end of 
four years growth, that changes in the ash, were accom- 
plished as indicated by a comparison with the ash consti- 
tuents of the uncultivated wild grape :—

and this striking increase was found to relate chiefly to an 
increased percentage of sugar and reduction of acid in the

Thus as the direct result of special feeding, the sugar per- 
centage of the wild fruit is increased from eight to thirteen 
per cent., a quantity nearly as great as that found in the 
cultivated Concord Grape at the same season. 
The significance of these results must be apparent to every 
intelligent cultivator, and to quote the words of the inves- 
tigator above cited, ‘“‘The ability to effect such decided
