GENERAL CULTURE OF STOVE PLANTS. 
These pipes convey the water from the boilers across the ends, and along the 
front of the house to the reservoir belonging each division at d, (see ground plan,) 
which is of the same dimensions as the boiler ; as the pipes, reservoir and boiler, 
are placed all on the same level, and filled about equally, within half an inch of the 
top, so as to allow room for circulating the heat regularly from end to the other. 
When the fire is lighted under the boiler, the water, as soon as it begins to get 
hot, immediately ascends to the top of the boiler, and flows along the upper pipe 
to the reservoir, when it forces the cold before it in the under pipe, back into the 
bottom of the boiler. The circulation of water is continued from one extremity of 
the house to the other : the hottest passing rapidly along the upper pipe, and the 
coldest returning through the lower one, back into the boiler, which will soon heat 
the pipes so as to raise the atmosphere of the house, in the severest weather, from 
seventy-five to eighty degrees, and that when there are twenty-eight degrees of 
frost. The pipes, boiler, and reservoir contain about 140 gallons of water ; when 
the fires are first lighted, every thing being cold and damp, it takes about an hour 
to heat the water to J 30 degrees; but when it is once heated, after the first night, 
it may be raised to the same temperature in twenty minutes. The furnace is 
attended from the shed behind (e). 
A very simple portable hot-water apparatus for heating conservatories, or other 
rooms, invented by Mr. Joshua Major, was exhibited near us some time ago, and 
shortly afterwards was figured in the Gardener's Magazine, from whence we 
extracted it and inserted it, vol. iii. page 181. The apparatus may be either made 
of tin or copper : the latter, though of course it would cost more at first, would, 
owing to its durability, no doubt be the cheapest. 
Charcoal is employed for heating : oil lamps have been tried instead of it, but
