GREENHOUSES ATTACHED TO DWELLINGS. 



The taste engendered by growing plants in rooms often 

 results in a desire to have more appropriate quarters for 

 the plants, and a greenhouse follows. This always affords 

 the most satisfaction when it is so attached to the dwell- 

 ing that opening a door or window from the dining- 

 room or parlor, reveals the glories of the greenhouse. 

 The greenhouse, when attached to the dwelling, should be 

 always on the east, south-east, south, or south-west sides, 

 never on the north. It may be of any length or width 

 desired. If of ten feet width, it will cost for erec- 

 tion from 84 to 86 per running foot, according to the 

 character of the work. If 20 feet wide, from 88 to 810 

 per running foot. This is exclusive of heating, which, if 

 done by hot- water pipes, will cost for 10 feet wide, about 

 $4 per running foot ; if 20 feet wide, about 68 per 

 running foot. Thus to complete a conservatory, with 

 heating apparatus, shelves, etc., 10 feet wide by 40 

 feet long, it would cost about 8400 ; if 20 x 40 feet, 

 about 8800. In this estimate it is assumed that the heat- 

 ing is to be done by the Base Burning Water-heater, 

 of Hitchings & Co. This heating apparatus is of recent 

 invention, and is exceedingly well adapted for the pur- 

 pose, as the fire requires no more attention than any 

 ordinary base burning stoves. The boiler takes up no 

 more room than an ordinary stove, and requires no set-
