PART V. CULINARY GARDENING. 279 



tention (see Chap. III.); but some effects which maybe produced 

 by particular modes of culture, though they are perfectly sim- 

 ple, and result from laws in the vegetable economy well known 

 to every practical naturalist, may deserve to be mentioned. 

 The first is, that when put into a hot and rather poor soil, as 

 lime rubbish, brick-bats, and stiff vegetable mould, the growth 

 will be limited, and the tendency to produce fruit greatly in- 

 creased *. Hence vines of this kind may be cultivated like 

 currant bushes, either in the open air, — under a frame or hand- 

 glass, — or in pots which may be forced in a hot-house or con- 

 servatory, or placed when in fruit in the drawing-room, &c. 

 A soil of an opposite kind, free, porous, and deep, such as 

 rough sand and light loam kept moist, will encourage the 

 growth of wood, and greatly lessen the tendency to produce 

 fruit. Hence the advantage which may be taken of this in 

 nursery gardening, where raising vines is an object, and hence 

 also the advantage which may be occasionally taken from it in 

 filling a large house with one plant. It is true, it would lessen 

 the production of fruit for a year or two at first ; but whenever 

 the house was sufficiently covered with shoots, by removing 

 part of the sand and free soil, adding some of a richer and more 

 hot nature, and giving less water, the whole tree may be thrown 



* This every attentive observer must have seen in the fields, whether in the 

 growth and fruitfulness of weeds, common crops, hawthorn hedges, or trees.
