On the Grafting of Vines.

of the stock. I tied it up, and clayed it over in the usual way, 

 with this difference, that I covered nearly the whole of the scion 

 with the clay, leaving only a small hole for its eye. I tied a little 

 moss over the clay, upon which I sprinkled a little water occasion- 

 ally, to keep the whole in a moist state for some time. 



Of the success of the plan I produced a proof to the Society in 

 September last, viz. a bunch of grapes produced from a strong 

 vigorous shoot of 22 feet of wood fully as well ripened as the rest 

 of the wood on the same vine. And I can now (May, 1835,) add, 

 that, having again commenced forcing, this shoot is fulfilling my 

 highest expectations. It has broken into leaf fully as strongly as 

 any other shoot on the same vine, and is shewing fruit. I have 

 been equally successful in my other experiments on the same 

 principle ; not fewer than 22 out of 23 grafts of the present 

 year have been attended with decided success; a number of 

 them shew fruit, and two of them two bunches each ; I am there- 

 fore convinced that vines may be grafted in this mode with as 

 much success as apples or pears, and with a sufficient certainty of 

 good bearing wood for the following season. 



What I thought, and still think, of essential importance to 

 success in this mode, is to leave the eye or young shoot on the top 

 of the stock, and allow it to grow for a few days : when it should 

 be cut off, leaving only one eye and one leaf to draw sap to the 

 scion, till it be fairly united to the stock. 



With regard to the time for grafting, I find that it will succeed 

 pretty well when the stocks are about to break into leaf. But I 

 think there is more certainty of success when the shoots of the 

 stock, into which the grafts are to be inserted, have made 12 or 

 15 inches of new wood. For instance, the grafts which I made on 

 the 25th of February this year, have not broken so freely, nor yet 

 advanced so far, as those grafted a month after when the stocks 

 had made about 15 inches of new wood. By this time the sap has
