THE GRAPE-VINE FAMILY. 571 



out of five grafts thus put on grew away freely. They were 

 only bound with matting, and probably clay or grafting-wax 

 would better secure the union. The advantages of this plan 

 will be patent to all." 



The influence of the Vine stock over the scion is amply 

 illustrated in the following quotations; and a well-conducted 

 and carefully-recorded series of experiments with Vine .stocks 

 would be of great value from a horticultural point of view. A 

 correspondent of the ' Florist ' writes : "I have growing here a 

 West's St Peter's, grafted on a Purple Constantia, and I find 

 the fruit greatly improved in flavour, while the berry is much 

 larger, and quite a fortnight earlier. The two adjoining Vines 

 are West's St Peters, and very healthy, one on its own roots, 

 the other grafted on the Black Prince; in these two cases 

 there is no perceptible difference. In another house I have 

 a Black Hamburg inarched on the Purple Constantia, using 

 the two stocks for the one Vine, and in this case the Ham- 

 burg is quite a fortnight earlier, and the fruit much richer in 

 flavour. The Vines on the Constantia appear to have the lead 

 in vigour of all the other Vines. In the same house is a Muscat 

 of Alexandria inarched on the Royal Muscadine, using the two 

 stocks for the Muscat Vine. On this Vine the fruit sets almost 

 to a berry, and is very vigorous. These Vines are freest, which 

 is a consideration greatly in its favour." 



Mr David Thomson contributes the following valuable infor- 

 mation : " We have the Gros Guillaume Grape so long mis- 

 called Barbarossa in two different houses, grafted on the 

 Muscat of Alexandria, and in another and cooler house on 

 Black Hamburg roots. In the Muscat house, and in the 

 cooler Hamburg house, we have it also on its own roots. 

 The results under these three conditions are strikingly differ- 

 ent. In both houses on the Muscat stock it swells its berries 

 much more regularly, and to a larger size, than it does on its 

 own roots in the same house, and on Vines of the same age. 

 In the cooler Black Hamburg house it neither makes such 

 large berries nor bunches ; but it colours much more rapidly 

 than in Muscat temperature on the Muscat stocks, or than it 

 colours on its own roots in either house. We have one vigor- 

 ous Vine on its own roots, in which there are just two mod- 

 erate-sized bunches ; but these two bunches are not nearly so 

 fine in berry as bunches four times their size on Muscat roots 

 under heavy crops. We consider this one of the noblest-look- 

 ing, and in every respect one of the best, late Grapes in culti- 

 vation ; and to those who wish to grow it to the greatest per-
