THE GRAPE 127 



no variety is superior to this, but the vine is tender 

 and often injured by diseases so that it has been dis- 

 carded, by many growers, as a commercial variety. It 

 must be planted near other varieties to have it pollenize, 

 as it is not self-fertile and fails to set full bunches when 

 planted alone. 



WHITE VARIETIES 



Green Mountain (Winchell) — The earliest good 

 white grape that produces a bunch of large size and 

 line quality. The vine is vigorous, hardy and produc- 

 tive, but the fruit is not of very attractive color, and 

 has not been largely grown for market. 



Moore's Diamond — This variety produces very 

 large clusters of beautiful fruit of good quality. The 

 vine is hardy and generally free from disease. It ripens 

 a little later than the Concord and for Northern locali- 

 ties is therefore not profitable. 



Niagara — The bunches, and the berries as well, are 

 a little larger than those of the last named variety, but 

 the color is not quite as good and it is a little later in 

 ripening. The vine is very vigorous and productive, 

 but is very much subject to disease, especially in the 

 >s^orth. 



Of the varieties of grapes of different colors, those 

 of a purple color sell the best, a very bright red, like 

 the Delaware, the next, and the white or green, unless 

 of a golden color, the poorest. 



GIRDLING THE VINE 



In Northern sections and with very late varieties 

 the crop is often cut off by early frosts in the fall, and 

 girdling (taking out a narrow ring of bark below the 

 fruit) is practiced to some extent to hasten the ripening. 

 The effect of this girdling is to stop the backward
