uniform size, not a single watery shoot being observable in 

 any of the houses. After the pruning is completed, a free 

 circulation of air is allowed, by means of the front sashes 

 and top-lights, and thus the breaking of the vines is con- 

 siderably retarded ; in fact, it is rendered later than upon 

 the open walls. In general, the vines do not begin to push 

 until the latter part of April, and it is only in the first week 

 in May that the houses are closed at night. Air is then 

 admitted less freely during the day ; the vines are frequent- 

 ly syringed, and abundance of water is thrown down upon 

 the floors, to keep up a constant supply of moisture in the 

 atmosphere. 



When the vines are in bloom, the houses are closed ear- 

 lier in the afternoon, and the syringe is of course dispensed 

 with, but is again made use of a few times after the grapes 

 are thinned, to wash off the remains of dead flowers and 

 dust, as well as to assist in restoring the leaves to their 

 proper position. Air is then given more freely during the 

 day in ivet as well as in dry weather ; for it is the opinion 

 of Mr. Crawshay, that the spots upon grapes, commonly 

 called " pitting," are caused by the stagnation of the at- 

 mosphere, which is consequent upon keeping a vinery 

 closed for several days during wet weather. As we before 

 stated, no water is admitted into the house after the color- 

 ing process has commenced ; but abundance of air is left 

 on through the night, as well as during the day. 



Through the whole period of their growth, no fire-heat 

 is applied; but when the grapes are perfectly ripe, and the 

 autumn frosts commence, Arnott's stove is used to preserve 

 the temperature of the house above the freezing point. 

 Thus but a trifling expense is incurred beyond the bare at- 

 tention necessary to insure success: and the fruit so pro- 

 duced, may with care be kept in perfection until February. 

 It is fruit too of which every gardener might be proud. 

 The bunches it is irue are not so large as we have seen ; 

 but in lieu of that they are compact and regular ; and very 

 few persons can produce berries of such a size. Not a 

 trace of the red spider is visible upon any of the leaves, 

 and the wood is already in the best possible condition for 

 another year. 



Such is the statement given in the Chi-onicle by Dr. 

 Lindley, of Mr. Crawshay's practice ; another visit to Mr. 

 Crawshay' s elicited some further information which is the
