PINE AND MELON PITS, 
little doors through which to pour water on the top of the flues, (j) 
gratings to admit heated air to the plants when requisite. (A*) back 
wall of the garden on which the chimnies are erected. The walk at 
the hack of each pit is one foot six inches wide ; the inside pit in 
which the plants are grown, is of the back pit seven feet six inches 
broad, and the height of the back wall seven feet six inches, and of 
the front seven feet high at the back wall, and seven feet broad across 
the pit, and each are forty feet long. 
I have also a pit heated with hot water pipes that I fruit pines in, 
which I like very much. 
It is built at a light expense, it is forty five feet long, there are 
flags placed over the head at the top; a hot water pipe runs along 
the front as well as back, and both descend into the the low pipe at 
the far end from the boiler, and return under the top pipe at the back 
3 
path ; the sloping part ( e.) over the front pipe is glass ; (a, a,) are 
three quarter round iron rods; ( b ) flags overhead at back; (d) front 
and back pipes; (e) pit 8 feet wide.
