Can any one inform a Doylestown, Bucks County Pa., correspondent if "Robert's portable patent terra cotta dry stove " for heating plant houses, can be obtained in this country, and if so from whom ? It was noticed in the London Garden, March 1st, 1873, in vol. 3d, and he thinks from the description given, it would suit admirably in a good sized plant cellar, which he uses for his Oranges, Lemons, Cape Jasamines, etc. It gets ample light from three large area windows; keeps out frost perfectly, and his plants thrive in it; but it is not warm enough to induce them to flower and set their fruit.
