EARLY DAWN. A new grape recommended by reliable par- 

 ties, who have tested it in Massachusetts and Connecticut. 



EARLY VICTOR. Good in Massachusetts, and promising in 

 other states. 



FOREIGN GRAPES UNDER GLASS. 



The number interested in foreign grapes is small ; still there 

 are occasional inquiries by those about to erect glass structures. 

 I have had no experience with such as require a long season and 

 artificial heat, only having grown about twenty varieties in a 

 common cold grapery. The Black Hamburgh is the standard 

 foreign grape, and its progeny is about as numerous as that of 

 the Concord. Among these the Gros Blue, Victoria Hamburgh, 

 and Wilmot's Black Hamburgh, have given good satisfaction. 

 The Golden Hamburgh is a shy bearer, and not recommended. 

 The Sweetwaters, both the Buckland and the White, have failed 

 to set their fruit evenly, and hence have given very imperfect 

 bunches. The Lady Downes and White Nice require fire heat 

 to bring them to perfection. White and Grizzly Frontignan 

 both succeed well, and the same is true of Bidwell's Seedling 

 and Bowker. Directions for preparing borders, the erection of 

 cold graperies, and for the training and management of Tines 

 under glass, are here omitted for obvious reasons. 



DISEASES ROT AND MILDEW. 



The rot and mildew are the worst enemies in the form of dis- 

 ease with which the grape-grower has to contend ; and yet, like 

 diseases in animal life, they are to a certain extent under his 

 control. I have only been troubled by mildew. It often de- 

 stroys both the foliage and fruit, as the fruit cannot mature in 

 the absence of healthy foliage. 



I have not been careful to keep the date of its appearance, 

 and doubt whether it is governed by any time-table. Dr. Fisher, 

 of Massachusetts, says, " It usually appears about July 10, 

 after a wet June. A wet June followed by a dry July causes 

 mildew, while a dry June followed by a wet July gives us free- 

 dom from this disease." Dry, powdered sulphur, though not a 

 specific for mildew in the open air, is perhaps the best remedy 

 at present known. Half an ounce volatilized on a warm sur-
