THE FOEEIGN GRAPE. 267 



Downing, contain all that is essential for a cold-house : " In a vinery 

 without heat this is comparatively simple. As soon as the vines com- 

 mence swelling their buds in the -Spring, they should be carefully 

 washed with mild soap-suds, to free them from insects, soften the 

 wood, and assist the buds to swell regularly. At least three or four 

 times a week; they should be well syringed with water, wdiich, when 

 the weather Ms cool, should always be done in the morning; and 

 every day the vine border should be duly supplied with water. 

 During the time when the vines are in blossom, and while the fruit 

 is setting, all sprinkling or syringing over the leaves must be sus- 

 pended, and the house should be ke^jt a little more closed and warm, 

 than usual, and should any indications of mildew appear on any of 

 the branches, it may at once be checked by dusting them with flour 

 of sulphur. Air must be given liberally every day when the tem- 

 perature rises in the house, beginning by sliding down the top sashes 

 a little in the morning, more at mid-day, and then gradually closing 

 them in the same manner. To n;uard as-ainst the sudden changes of 

 temperature out of doors, and at the same time to keep up as moist 

 and warm a state of atmosphere within the vinery as is consistent 

 with pretty free admission of the air during sunshine, is the great 

 object of culture in a vinery of this kind. 



Insects. The aphis or " vine-fretter^ is destroyed by fumigating, 

 i, e., burning tobacco in the house, and syringing the vines freely 

 afterward. If red spiders are troublesome, syringe the vines at 

 evening, and dust the leaves with flour of sulphur. 



VARIETIES. 



Feeling that a multiplicity of varieties would only mislead and 

 confuse the practical man, and our own experience with foreign 

 grapes not having been sufficient to enable us fully to decide on 

 which to recommend, we adopt and describe few besides those voted 

 worthy of general cultivation by the American Pomological Society. 



Black Hamburgh. 



Valentino's, | Salisbury Violet, 



Purple Hambursrh, I Gibraltar, 

 Browu Hamburgh, Frankendale. 



"Warner's Black Hamburgh, 

 Red Hamburgh, 

 Dutch Hamburgh, 

 Hampton Court Vine, 



This variety is one of the most esteemed for the vinery. In sheltered 

 locations, out of doors in cities south as far as Cincinnati, it does well with 

 protection in Winter. A good bearer.=^ Bunches, large, shouldered on 

 both sides ; berries, very large, roundish inclining to oval, brownish purple, 

 becoming purplish black when fully ripe; of sugary rich flavor. 



Wilmot's New Black Hamburgh is similar. Fruit, larger, bloom \"ery 

 thick ; Jlcsh, firm, nearly or quite equal to the common Hamburgh. 



* A vine of this variety at Hampton Court Palace, planted in 1769, is stated to produce an* 

 nuftlly over one ton weight of fruit.
