74 OPEN AIR GRAPE CULTURE. 



less are so situated locally, as to possess little or no 

 soil at all on the surface adjoining their sites; the 

 ground being either paved with bricks or stone, or per- 

 haps trodden- so hard, as to be apparently incapable 

 of yielding sustenance to any vegetable production. 



" In all such cases, however, if the ground adjoining 

 the site of the wall or building be opened to the 

 extent of eighteen inches square, and as many deep, 

 it will be sufficient to admit the roots of a young 

 vine, which must be pruned to suit that space. If a 

 wider and deeper space can be made, it will of course 

 be better ; but if not, that will do. After the sides 

 and bottom have been loosened as much as possible, 

 the vine may be planted and the hole filled up with 

 two-thirds of rich loamy earth, and one-third of road 

 scrapings, previously mixed well together, and if 

 necessary the surface covering, whether of stone, 

 brick, or otherwise, may be restored again to its for- 

 mer state, provided a space about six inches square 

 be left open for the stem to swell in during its future 

 growth. Vines planted in such situations, will in gene- 

 ral do well, although their growth will not be so rapid 

 as when planted under more favorable circumstances. 



" In all cases where vines are planted against any 

 description of buildings, their roots push as soon as 

 possible under the foundations, being attracted thi- 

 ther by the warm air which is there generated ; and
