64 Plan for Forcing Sea Kale, &c. 



/ 2 3 4- S 6 



Scale of half an inch to a foot. 



'Reference to the Figures. 



1. The bed in which the Kale grows. 



2. The trenches filled with dung. 



3. The garden frame over the bed, placed upon the dung. 



The same plan is applicable to the forcing of Asparagus ; 

 the heat of the linings, which may be renewed if necessary, 

 penetrates into the bed, and forces the plants to grow 

 rapidly. I am, Sir, 



Your humble servant, 



Thomas Baldwin. 



Ragky, November 13, 1819. 



Note by the Secretary. 

 This method of forcing is applicable to the early produc- 

 tion of Rhubarb, or any other perennial vegetable which 

 may be required in a garden ; but it does not seem neces- 

 sary to place the glass lights on the frames when the plants 

 are to be blanched, a covering of wood, or mats of sufficient 

 thickness, need only be used in such cases.
