Other forms are also chosen for convenience, such as the 

 cylindrical, with the branches trained spirally round, fig. e, 

 pyramidal, fig. f, umbrella, fig. g ; these last-mentioned forms

are generally adapted to the pear or plum, and are much 

 practised in France. Corridor and arbour training is also 

 performed with the vine, but, except in particularly warm and 

 dry situations, the fruit seldom ripens. 



A lately invented trellis has been adapted to vineries in 

 Scotland, which has merit ; they are called pendent trellisses, 

 because they are attached to, and hang from the rafters of the 

 building ; they are composed of a slight frame of laths or wire, 

 of the same width of the rafter, the exterior sides of it forming 

 an extended surface, on which the vines are trained ; the lower 

 edge is curvilinear, giving head room at back and front. 

 (Loudon's Gardeners' Magazine). 



Mr. John Long, builder, Chelsea, has invented a moveable 

 trellis for vines ; it is fixed with hinges at bottom, and can be 

 elevated or lowered by puUies, according as the weather may 

 render necessary, or the management ;f the trees require. 

 Both those schemes are improvements, and serve to show the 

 resources of a fertile mind when once induced to leave the 

 beaten track of rules and reigning fashion. 



Acclimating the valuable fruits and forest trees of warmer 

 climates is a point of the utmost national importance, and 

 ought to engage the attention of every man employed in 

 gardening. It is known, and we have several instances of the 

 fact, that the constitutions of plants may be altered by cultiva- 

 tion. The qualities which render plants obnoxious to frost, 

 are the aqueous nature of their sap, which renders it easier of 

 pongelation, and the fragility or want of toughness, or elas- 

 ticity of the fibre, which allows the laceration and destruction 

 of the vessels. Plants seem, therefore, fitted to their respective
