This variety, of ancient and unknown origin, dates back at least to 1792 when Truchsess received it from Christ under the names Grosse Frühkirsche 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 France, Double Glass has long been cultivated under the name Amarelle Double de Verre. The variety was brought to America from Russia in 1883 by Professor J. L. Budd. While grown for a time in the Central States it was never highly regarded and has now nearly passed from cultivation. The following description is a compilation: Tree large, vigorous, upright-spreading becoming divergent with age, usually hardy, rather unproductive; branchlets thick, reddish-brown; leaves healthy, small to medium, ovate, with serrated margins; buds large, prominent. Fruit matures the latter part of June; usually large, roundish-oblate, with a very deep suture; color light red becoming much darker at maturity; stem long, thick; skin thin, tough, translucent; flesh yellowish, with abundant uncolored juice, firm, tender, sprightly; good in quality; stone medium in size, roundish.

Cultural tests soon demonstrated, however, that most of the varieties were comparatively worthless; Double Natte is one of these. It is a very mediocre cherry of the Morello group in nowise equal to English Morello except when earliness is a prime requisite, this sort being one of the earliest of the Morellos. In flavor it is equal to English Morello but is no better. At Geneva the trees are seldom very fruitful. From the eulogistic reports of its behavior in the Middle West it would seem that it was better adapted to Iowa, for instance, than for New York. This variety was first mentioned by Knoop, the Dutch pomologist, in 1771--origin not given. Some years ago Professor J. L. Budd also imported from Russia a cherry under the name Riga No. 18. This cherry has been grown as a separate variety under the name Riga but the descriptions of it are all identical with those of Double Natte and there can be no doubt but that they are one and the same.
