 one or more divisions of about forty feet long, six- 

 teen feet wide;" the back wall thirteen feet, and 

 the front wall nine feet, the upper four feet being 

 composed of sliding sashes. The slope in the roof 

 will, by these dimensions, be four feet, or about 

 three inches to a foot. The pit is to be surround- 

 ed by a path, which behind will be four feet higher 

 than in front, and, consequently, the end paths must 

 have steps. The fire-place being placed in the 

 back wall, and supplied from the shed behind, the 

 flue should be carried round about the inside, 

 stretching from the fire-place across the end and 

 along between the path and the front wall, leaving 

 a cavity of four or five inches wide between the 

 flue and the wall, to admit the heat to rise freely, 

 and to prevent the roots and stems of the vines 

 planted in the border against the front wall from 

 being too much heated. At that end of the divi-

 house under the back path, the flue must rise

 is to be made nearly three feet deep, seven inches 

 wide, and when it riseth above the back side

 should be about three feet feet six inches deep of 

 brick, on edge two inches thick, besides the plas-
