I see by the January number that Miss W., of Quaker Hill, N. V., makes inquiries about heating a small plant room or greenhouse. I have a greenhouse 11x24, that I have kept warm all winter so far, with oil stoves, and I have no trouble in keeping heat anywhere from 50° at night to 80 in the daytime. I use two oil stoves. Each has two four-inch wicks, and so far I have used about one gallon of oil for each stove every twenty-four hours. I have the stoves on the ground, under the bench, fastened by wire to the bottom of the bench.' I have common stove pipe, which runs the full length of one side, and across the end, and one-third the way down the other side. Then it runs up, and out at the top of the house. I have a common elbow where the pipe commenced, and under that I set one stove, and two-thirds the length further down (or 16 feet from the first) I have what the tinners call a T elbow, that is an elbow in the shape of the letter T. So that the pipe connects all the way. The piping is up high enough, so that I can take stoves from under the pipes and trim and fill them, and the cold air passes up into the pipe, and so keeps the greenhouse in a nice even temperature.

I have geraniums, pinks, fuchsias, hibiscus, heliotropes, verbenas, tuberoses and other plants in bloom, and everything seems to be doing well, so that by spring I shall have more than the house full. The thermometer outside has been down to 10° above zero two or three times this winter, yet I have kept the greenhouse with only the two stoves, so that the heat has never been lower than 480 at any time. For a • small greenhouse, I think the oil stoves are just the things in connection with stovepipe.

By the way, I like the Gardeners' Monthly very much, and shall soon send for some of the books your publisher has for sale, as I want everything that talks and teaches about flowers. I think some of them almost talk. Pansies seem to laugh every time you look at them.
