Of forcing Grapes by Artificial heat. 



IN all parts of England, grapes may be 

 improved by ftove walls, either with 

 or without covering of glafs, and in the 

 north parts of the kingdom there ought 

 to be fuch conveniencies in all large gar- 

 dens, for in wet feafons very few grapes 

 will ripen without them, neither will fome 

 of the moft valuable kinds which I have 

 mentioned in the catalogue, ever ripen in 

 the moft favourable feafon by the natural 

 heat of the fun alone. Walls for that 

 purpofe are built after different methods, 

 and fometimes vines are planted by the 

 fide of a ftove or green-houfe, built for 

 the prefervation of exoticks, and the 

 branches drav/n into It through fmall holes 

 left for that purpofe ; and tied or nailed 

 to bars of Vv^ood near the glaffes.
