Having had a short but very satisfactory experience in the use of coal oil stoves for heating small conservatories, I would have no hesitation in recommending them. I use mine at present more as an auxiliary.

Having built an addition last year to my greenhouse, and not wishing to go to the expense of enlarging the flues, I procured a No. 3 Florence stove, holding about three quarts, with three wicks, and would not be without it. One night, with the thermometer outside at 180, I raised the temperature some 6° in twenty minutes, and that in a house 12x30, glass on three sides. The heat is steady as long as the fuel lasts. By actual test, with the above mentioned supply, mine has burned fifteen hours. I think seriously of putting one in my fernery next fall. I think Miss W., of Quaker Hill, N. Y., would find one of these stoves the very thing for the purpose she desires.
