The Hot-House. 



The renewal system of grape culture may be applied 

 to the Hot-house iu precisely the same way as to the 

 vineyard and Cold Grapery. The design of this work 

 does not permit us to give detailed instruction in the 

 general management of the hot-house, and we shall 

 therefore only say that iu houses with very long rafters, 

 say fifteen to twenty feet, the weaker kinds of grapes 

 will not probably grow strong enough, upon this system, 

 to fruit them the whole length of the rafter the first 

 year or two, but they should be cut back in proportion 

 to their strength. Some of the strong canes can be 

 fruited the second season, half way up the house, say 

 ten feet. Others, if weaker, should be cut back to four 

 or six feet of fruiting wood. The second time of fruit- 

 ing, the weaker vines can be extended to ten feet, and 

 the third time the entire length of the rafter. 



In small hot-houses, with a rafter only eight or ten 

 feet long, the canes may be planted in the spring, and 

 one-half of them (as before directed,) may be fruited the 

 entire length of the rafter the second year. Small 

 houses, with rafters only six or eight feet long, are the 

 best size for early forcing.
