_Gentlemen_:--The mills purchased of you last May, set up and started by David Carey, have given entire satisfaction. Our mill consists of two run of 30-inch upper-runner burrs, pulley mills--one for corn and one for wheat--can grind from seven to ten bushels of wheat into the best merchantable flour, and from ten to fifteen bushels of corn into fine meal, per hour on each burr. Our bolt is sufficient to bolt the above amount, and performs well. Our mills and machinery is driven by an engine, 8 by 16-inch cylinder, and runs 170 revolutions to the minute. We can run the entire machinery ten hours on three-fourths of a cord of wood, have been running almost every day since we started up. Our custom is still on the increase, extending over a great amount of country. We run now every day, while other mills in town and immediate vicinity do not run now to exceed two days in the week. Your mill and bolt arrangement is the only thing suitable for custom, and does well for merchant work. We would recommend persons who think of buying mills, to give you a call--or if we purchase again we will do so. We will take pleasure in showing any one our mill. Yours, respectfully, CAREY & ROBERTS. Lay by Your Old Notions.--36 inch and 30 inch Pulley Mills. CUMBERLAND, Guernsey Co., O., Feb. 14, 1870. NORDYKE, MARMON & Co.:-- _Sirs_:--We have used your mills since the 4th of last November. We consider them durable as any mills can be. We can grind on our 36-inch wheat mill from fifteen to twenty bushels per hour, owing to the grain, and can make flour that will satisfy any community, both in regard to quality and quantity. On our 30-inch corn mill, we can grind forty bushels per hour, if the corn is dry. Our miller says he can make forty barrels of XX family flour in ten hours. We have a twenty-five horse power engine. Our boiler is twenty-two feet long, for two inches in diameter, and two flues. It affords enough power, under seventy pounds pressure, to drive both mills together with their attendant machinery, which is one of your twenty-two foot Flour Bolts, No. 1 Richmond Smut Machines, Buckwheat Bolts, Elevators, Shafting, &c. Three bushels of coal per hour is all we require. To those wishing mills we would just say they had better lay by their old notions and procure improved mills. Yours, &c., HOWELL BROTHERS. Mill and Bolt Cannot be Beat. HAMBURG, Fremont Co., Iowa, Jan. 11, 1869. MESSRS. NORDYKE, MARMON & Co.:-- _Dear Sirs_:--I have had one of your 36-inch Pulley Mills and 18 feet Bolt in operation nearly one year. I like it very much; my flour gives general satisfaction; am averaging ten bushels of wheat per hour on the one pair of burrs, making the best flour. In short, I think your Mill and Bolt cannot be beat. It is driven by one of Leffel’ 20-inch Double Turbine Wheels, under a total head and fall of 11 feet 9 inches. Yours, respectfully, H. LAMB.
