STATEMENT.

ORDINARY FURNACE, from 15th to 20th April, produced 23,195 lbs. of Muck Bar, and 295 lbs. Sc.r.a.p Bar, worked double turn. Day turn started at 3 A.M., and was done by 1 P.M. Night turn went on at 2 P.M., and was done by 11 P.M., worked 5 heats to each turn. Consumed 350 bushels of coal.

Furnace was lighted on Sunday out of coal. The Stevenson Furnace, from 15th to 20th April, produced 29,160 lbs. of Muck Bar, and 515 lbs. of Sc.r.a.p Bar, worked double turn. Day turn started at 3 A.M., and was done by 10 A.M. Night turn started at 11 A.M., and was done by 6 P.M., worked 6 heats to each turn. Consumed 300 bushels of coal. Furnace was lighted on Sunday out of coal. The same weight of heats of Pig and Sc.r.a.p were weighed to each Furnace. On Stevenson Furnace, 3,963 lbs. more Muck Bar, and 220 lbs. more Sc.r.a.p Bar were made, with 50 bushels less coal than were used in other furnace. The saving in ore (fix) in former over latter during the week, was 450 lbs., by actual weight. A very important feature is the great saving accomplished in brick and brick-laying. The first Stevenson Furnace, put up three months, has not had any repair put upon it, and is, to-day, in good working order, while the ordinary furnaces are generally repaired about every two weeks. The cost, over ordinary furnace, is about seventy dollars.

We cheerfully bear witness to the truth of the above statements of Mr.

Stevenson. They are rather under than over the mark. The quality of iron made in his furnaces is the same as made by ordinary kind. We think it a valuable improvement, and intend to introduce it as fast as possible in our forge. J. PAINTER & SONS.
