The reader will be attracted in the present number with the portrait of a small conservatory made in a bay window of our own dining-room at a small cost. With regard to a system of warming a greenhouse or conservatory attached to a house, there ought to be no difficulty in employing a house fire for the purpose. In the case introduced, the heat from the dining-room fire has answered perfectly. Many modes may be adopted according to circumstances. One has just struck us in a foreign journal: -
"A neat little lean-to house was placed against the garden side of a mansion. The floor was some five feet above the furnace that heated the scullery copper; a small flue was made underneath that floor, from the same furnace, and the draught let on or off; by means of dampers, without any bother with additional fireplaces or chimneys".
In another case,"A merchant built a nice residence for himself a few years ago. A neat flower garden was on the east side of the house, communicating by folding doors with the living-room, the floor being about two feet above the level of the garden. He wanted a greenhouse to be easily accessible, and easily managed. It was recommended to have it communicating with the above room, and between it and the flower garden; and to be heated from the kitchen boiler immediately beneath that room. After mature consideration, he placed his greenhouse on the west side of his house, that he might have something attractive on every side; and his plan would have been successful but for the fact that he had an unsuccessful smoke-oonsnming furnace, instead of passing his smoke out of the lofty chimneys. We have yet much to learn on this subject of wanning, and on saving the heat now disseminated to the winds".
