 healthy green color.

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 $4 to $6 per running foot, according to the 

 character of the work. If 20 feet wide, from $8 to $10 

 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 $8 per 

 running foot. Thus to complete a conservatory, with 

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

 feet long, it would cost about $400; if 20 x 40 feet, 

 about $800. 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-
