The preceding sketch represents a transverse section 

 of the vinery, with bed for tree leaves to decay and 

 heat ; framework for the support of front trough, 

 sixteen inches wide at top, and ten inches deep, and 

 the wire under the rafters on which the vines are 

 trained. (United Gard. and Land Steward's Jonrn.) 



Preparation for Forcing. — Mr. Arkwright proved 

 that vines, of which the wood and fruit have ripened 

 late in one season, will vegetate late in the following 

 season, under any given degree of temperature ; and 

 Mr. Knight has shewn the converse of this proposi- 

 tion to be equally true ; the plants under each differ- 

 ent mode of treatment requiring a period of rest, 

 during which they regain their expended excitability. 

 A Verdelho vine, growing in a pot, was placed in the 

 stove early in the spring, where its wood became per- 

 fectly mature in August. It was then taken from the 

 stove, and placed under a north wall, where it re- 

 mained till the end of November, when it was re- 

 placed in the stove ; and it ripened its fruit early in 

 the following spring. In May it was again trans- 

 ferred to a north wall, where it remained in a quies- 

 cent state till the end of August. It then vegetated 

 strongly, and shewed abundant blossom, which, upon 

 being transferred to the stove, set very freely ; and

 very high temperature, ripened early in February. 

 The plant retained its foliage till April, and would not
