laying down and covering with a few inches of

Black Hamburg, so me times called Red Hamburg. 

 Fruit large, deep purple, regarded as the finest of 

 all exotic grapes, but less hardy than the Sweet 

 Water, and cultivated chiefly in grape houses. 



The White Muscat of Alexandria, is a large and 

 very fine grape, but requires the heat of a grape 

 house* 



DISEASES AND ENEMIES. 



Various insects occasionally attack the vine, but 

 they are rarely numerous or formidable. The only 

 serious difficulty appears to be mildew, which is 

 confined to exotic grapes. These, especially the 

 White Sweet Water, do well for three or four 

 years, and then become worthless. No means for 

 preventing the disaster appear to have proved en- 

 tirely successful, except by the successive produc- 

 tion of new plants every two or three years, by lay- 

 ers from the old vines, which are then destroyed. 



KEEPING GRAPES THROUGH WINTER. 



Grapes, packed in large jars, in baked saw-dust, 

 or in cotton batting, by alternate layers of the grape 

 and the packing, and then excluded from the air 

 by sealing the cover with wax or tallow, will keep 

 in a cool place till mid-winter or spring.
