THE CULTURE OF THE GRAPE. 79 



years, I am determined to add my testimony to tliat of Mr. 

 Parks, that some good may be effected by leaving air in the 

 house all night, &c. &c." This writer agrees with Mr. Parks 

 in the plan of giving air as the remedy, but does not admit 

 that the length of the footstalk can be the cause. 



Vol. 12, page 244. Mr. Jasper Wallace thinks that " the 

 principal cause of the shrinking of grapes is owing to the 

 ROOTS BEING OVERHEATED and not having sufficient moisture, 

 when planted in the inside border." 



Vol. 13, page 261. Mr. J. Robertson, Nurseryman, says : 

 " There has been much discussion in your magazine on the 

 cause of, and remedy for, the frequent shrivelhng of grapes, 

 about the period of ripening, in stoves and vineries. Being 

 unluckily privileged, by my own ill success, to offer an opin-

 turning black, but now, after another year's practice, chance, 

 as it often does, has thrown in my way something which I 

 never could have discovered without it. I am convinced, that 

 too moist an atmosphere is not the cause of the shrivelling of 

 grapes, but that it arises from the inability of the vine to pro- 

 vide a sufficient quantity of nourishment for the berries. The 

 inability of the vine to provide for its fruit may arise from 

 different causes, such as overcropping, the foliage being too 

 crowded, &c." 



Vol. 16, page 598. By W. H., (Mosely Hall.) " Sev- 

 eral articles have appeared, at different times, in the Garden- 

 ers' Magazine, on the shrivelling of grapes. I have tried 

 every one of them, as they made their appearance, but with- 

 out the least success. In Dr. Lindley's Theory of Horticul- 

 ture, article Bottom Heat, it is there stated that the cause is,
