Under a more recent date we quote from another letter: “I am running the mills yet with better success than ever, making good flour and large yields. On several tests have made 47½ lbs. lately of excellent flour from ordinary red wheat. If you could give me some information about keeping the furrows in the stones in order to grind cool and fast, I would be thankful; as far as keeping in tram and cracking the face, I am doing very well. I grind close and bolt clean. I have taken 60 lbs. of good white wheat and made 50 lbs. of flour. What do you think of this? The farmers say I can beat any mill they have tried. Please answer, and give me all the instruction you can. It may be best for me to get a No. 1 Dresser to work on the furrows some, and I may catch items by it. I have an order from New York for 100 bbls. of flour at this time. I would like to exchange a half dozen of those light picks you sent me for heavy ones, and pay the difference. I like a 2 pound pick the best for light cracking. Yours truly, ANDREW CLEMMER.” Three Geared Mills. No Expense for Repairs. GREEN CAMP, Marion Co., O., March 22, 1870. MESSRS. NORDYKE, MARMON & Co., Richmond, Ind.:-- It gives us pleasure to write that we have used the Mills furnished us by you, since May 28, 1868--two 42 inch Wheat, one 30 inch Corn under-runner. The Wheat Mills have run ever since without one cent repairs, and without any apparent wear--the balance being so perfect, and being put up in so substantial a manner. They give entire satisfaction, always doing their work in the best possible manner. The two 22 feet Bolts are all that we could wish, doing their work well, without one cent’ repair. The Corn Stone, under-runner, 30 inches, will do double the work of 42 inch upper-runner Corn Mills, and do the work _well_. The Smut Machine always does its work well. The work was all put up in so substantial a manner by your James Albertson that we have never made any repairs, only to replace perforated zinc on Smut Machine. Our flour always brings the highest prices. Yours, respectfully, FOSTER & KANABLE. Cannot do Better. WESTFIELD, Hamilton Co., Ind., Jan. 8, 1869. MESSRS. NORDYKE, MARMON & Co.:-- _Gentlemen_:--In answer to your letter of inquiry of Dec. 30. Your mills are doing well, they are giving as good yields and better flour than the large, old style mills. Your 30 inch upper-runner mills for wheat, grind from six to ten bushels of wheat per hour, and your 36 inch mill from eight to twelve bushels of wheat per hour. By crowding a little when the stones are sharp, will grind much more than I have stated. Your bolts and smut machines work well; your mills run light, considering the work to do. A 15 horse power engine, 8 by 16 inch cylinder, will drive two run of your 30 inch mills,--60 pounds of steam,--and will drive them twelve hours with one cord of wood. I think all wanting mill machinery cannot do better than to order from the “Richmond Mill Works.”
