outside border, marked a on the plan. 
The borders being all covered, and the means of warming 
them provided, the roots of the vines could be got into a state 
of activity before the house is finally closed. As these borders 
would entirely depend upon the gardener for their supply of 
moisture, it must be given with no niggardly hand, as the 
vine, when in growth and carrying a crop of fruit, requires 
plenty, which should not be given quite cold ; it should also 
occasionally contain a good dash of the drainage from the 
stable or cow-house, to keep up the fertility of the soil. 
The subjects usually brought into the forcing-house arc 
kidney-beans, potatoes, and strawberries. On each of these a 
few remarks will in this place be appropriate. In respect of 
sea-kale, asparagus, and other subjects that are forced in pits 
and frames or in the beds thej^ permanently occupy, informa- 
tion will be found in the chapters which treat of their cultiva- 
tion generally.
