PLATE XII. 
Contains the elevation of the circular end of the last Stove, and the transverse section of the same 
end. The entrance is seen on the side of the elevation ; in the section the disposition of the internal 
parts is shewn, being drawn up from the plan under it, as the elevation is from the same, inverted : 
the position of these stoves (in respect to their length) is north and south. This disposition would 
have been more perfect if the path had been carried round the pit, as in Plate XV. and would then 
receive large plants; the centre path should also be contracted, when the stove is erected solely 
for use.
