46 RIVAL SYSTEMS OF VINE-CULTURE. 



place even when the " restrictive system " is adopted, 

 and it will take place with infinitely greater rapidity 

 under the other. To meet this difficulty the roots have 

 been walled in ; but this only aggravates the evil, for 

 the moment the roots touch the wall, they descend to 

 the bottom of the border, where they are far from the 

 genial influences of heat and air. 



Another objection brought against this system is, that 

 one vine takes much longer to furnish a house with 

 fruit than a number do ; but this can be met by plant- 

 ing supernumeraries, to be removed as the permanent 

 one advances. 



A third objection is, that variety of grapes is desir- 

 able in a vinery, and that this cannot be had where 

 only one vine is grown. Grafting or inarching will 

 meet this objection; and it is well known that many 

 delicate sorts of vines grow better on other than their 

 own roots. 



Thus it appears that the only serious objection to the 

 one-vine system is the difficulty of getting a border of 

 sufficient scope for the roots of a vine of such propor- 

 tions as will fill a good-sized vinery with fruit-bearing 

 wood ; but where such can be had, I fully approve of 

 the " extension system/' and will now proceed to give a 

 detailed account of one of the best and most successful 

 examples of it known to me, and with the origin of 

 which I had some connection. 



In the year 1838 I became acquainted with the late 

 Mr Peter Kay of Finchly, near London, and up to the 

 date of his melancholy death I continued to discuss 

 with him, verbally and by letter, every question that 

 bore on the culture of the vine. He always maintained
