For information about burning lime we republish the following article furnished by a correspondent of the _Country Gentleman_ several years ago: [Illustration: Fig. 1. Fig. 2. Fig. 3. A (Fig. 1), Railway Track--B B B, Iron Rods running through Kiln--C, Capstone over Arch--D, Arch--E, Well without brick or ash lining.] I send you a description and sketch of a lime-kiln put up on my premises about five years ago. The dimensions of this kiln are 13 feet square by 25 feet high from foundation, and its capacity 100 bushels in 24 hours. It was constructed of the limestone quarried on the spot. It has round iron rods (shown in sketch) passing through, with iron plates fastened to the ends as clamps to make it more firm; the pair nearest the top should be not less than 2 feet from that point, the others interspersed about 2 feet apart--the greatest strain being near the top. The arch should be 7 feet high by 5½ wide in front, with a gather on the top and sides of about 1 foot, with plank floor; and if this has a little incline it will facilitate shoveling the lime when drawn. The arch should have a strong capstone; also one immediately under the well of the kiln, with a hole 2 feet in diameter to draw the lime through; or two may be used with semicircle cut in each. Iron bars 2 inches wide by 1/8 inch thick are used in this kiln for closing it, working in slots fastened to capstone. These slots must be put in before the caps are laid. When it is desired to draw lime, these bars may be pushed laterally in the slots, or drawn out entirely, according to circumstances; 3 bars will be enough. The slots are made of iron bars 1½ inches wide, with ends rounded and turned up, and inserted in holes drilled through capstone and keyed above.
