68 FRUIT CULTURE UNDER GLASS. 



soil is of a character decidedly unfavourable, it is 

 desirable to confine the roots within the limits of the 

 artificial border. This can be done by a brick-and- 

 cement wall. Where the natural soil is favourable, 

 this is of less importance for late grapes ; but for 

 grapes that have to be ripened not later than June, 

 it is desirable to have all the roots in the made 

 border, and thus under control. 



VARIETIES OF GRAPES. 



The varieties of grapes cultivated in this country 

 have increased considerably of late, both by the in- 

 troduction of Continental varieties and by the dis- 

 tribution of seedlings raised in Britain ; consequently 

 the inexperienced have greater difficulty than ever in 

 making selections to meet their wants. The follow- 

 ing are the varieties I recommend for early forcing in, 

 say, a 40 -feet vinery admitting of 13 rods:
