It is now three years since we overhauled our mill and put in your improved machinery; since which time it has been run almost daily as a custom mill, and in quality and quantity of flour gives universal satisfaction. In fact, the custom increased one-half since its introduction. We find it very permanent and durable, as well as tasteful in style and finish. We can grind at least 10 bushels per hour with each run of burrs, and use from one to one and a fourth cord of wood in ten hours’ grinding on all three stones. We would recommend all desirous of purchasing mill machinery to procure yours, believing their money will be well invested if they do. Yours, truly, HADLEY & TAYLOR. MADISON, Indiana, May 6, 1872. _Gents_:--Yours of the 3d inst came duly to hand, making inquiries how we are pleased with our mills that we purchased of you over three years since, (we expected to write you before this.) If you remember our Burrs are sharp old quarry, not very open, and they make very lively flour, and don’ get dull as soon as most others. Our stones are, two pair of upper-runner 3 feet mills. We make a barrel of flour with 3 pecks of coal; we do not know that we could say anything more, excepting that they work fine, and together with the bolt you made for us, make flour that we can find ready sale for in any market along with the best brands. Your flour bolt deserves special mention; with the knockers or “percussion apparatus,” as you term it, which we can stop or start at any time while the mill is running, we are able to keep the bolt clean and bolt through the fine cloth without specking or injuring the flour. The arrangement of the bolt for clean bolting, we think is your best effort. Very truly, yours, W. W. & B. F. PAGE. The above is from Madison, Indiana, 60 miles below Cincinnati, on the Ohio river. ROCHESTER, Ind., Feb. 14th, 1872. MESSRS. NORDYKE, MARMON & Co.:-- _Gentlemen_:--Our custom work runs from 60 to 250 bushels per day of wheat, besides a large amount of corn. Although there are several mills here, our flour has the preference, and sells more ready than any; the self-tram irons are perfect. You shall hear from us again. Yours, truly, A. L. BOWMAN & Co. This mill is composed of two run of our 42-inch and one run 30-inch in combined husk, the two former being upper-runner, latter under-runner. They use our 20 feet double reel bolt and other supplies for the complete furnishing of a mill. Two 30 Inch Pulley Mills. CARMEL, Hamilton Co., Ind., Jan. 4, 1869. NORDYKE, MARMON & Co.:--
