Double Glass is a Dttke, a hybrid more nearly resembling the Sweet 

 Cherry than the Sour Cherry. The trees grow remarkably well in nursery 

 and orchard and their behavior so pleased growers when the variety was 

 brought to notice that it became for a time quite the vogue. But the 

 trees ttamed out to be unproductive and the cherries so mediocre that 

 the variety rapidly passed through its heyday of popularity. The fruits 

 are curiously marked, the suture being so deep as to make them appear 

 double — hence the name. The variety has no value where sweet sorts 

 are hardy but possibly might find a niche somewhere in regions where a 

 more tender Sweet Cherry cannot be grown. 



This variety, of ancient and unknown origin, dates back at least to 

 1792 when Truchsess received it from Christ under the names Grosse 

 Friihkirsche and Englische Erzherzogskirsche, both of which were incorrect, 

 the first because it was not characteristic since the fruit did not ripen early, 

 and the second because it denoted a class of dark-fleshed cherries. In
