"Mrs. S. K. D. M.," Buffalo, N. Y., writes the following list of queries, to which we have already replied in a private letter; but insert here in the hope that correspondents will also give their views:

"What will be the best method of heating a very small greenhouse (5x9), which I propose adding to the south side of my dining-room. It would be entered by a double French window from the dining-room, and the plant bench would extend all along the east, south and west sides, just leaving space in the center to stand and work. I propose to floor it with brick, and carry a pipe from the house hot air furnace (twenty feet away) under the bench and back into the room. Will this radiate heat enough to keep the plants in good condition? If not, can some one advise me what will be the best method of heating the place? Our winters here are long, cold, and devoid of sunshine. Any suggestions about construction, etc, but especially heating, will be most welcome. I notice your magazine suggests the Florence oil stone. Do not they smell badly? And what is the best simple way of ventilation and drainage for so small a space? And will it do to have the bottom filled with earth, and plant a hardy climbing rose, or something of the sort, that would grow under the brick floor? I would not trouble you, but in books I can only find directions for much larger places, and it must be possible to arrange a small place, well exposed as this is, and get good results.

Some one must know how."
