15 inches, and width, 5f inches, by 7i inches; the fire-pan is 5| in. 
by inches, and 3^ inches deep; surrounded on three sides bv a 
boiler half an inch in diameter, which becomes more spacious up¬ 
wards, as the fire place diminishes. The opening necessary for the 
reception of the fire-pan, and for supplying it with fuel, is 6 inches 
wide, by 5i inches deep; at the top of this opening the fire-place 
commences tapering ; consequently the water in the boiler expands 
more immediately over the fire ; the smoke pipe takes its regular 
width, inch, in the boiler, about an inch below where the lid 
unites; the horizontal water pipes (a) fig. 17, are each 28 inches 
long, by two inches in diameter; the end pipes ( b ) are 14d inches, 
by 3 inches diameter ; a feeder (c) is added, in case it should be 
thought better to have the lid fixed tight on the boiler. In order to 
promote the circulation of the water small holes are to be perforated 
in the top of the lids (d d) which are also intended to be fixed tight. 
The apparatus may either be placed on the floor of the place to be 
warmed, or raised by bearers, or suspended by wire or cord, the 
two latter methods assist the fire to burn more freely.— Gardeners
