In a letter dated December 19, 1871, they say: Our custom has increased to from 90 to 145 bushels per day; doing this and our own grinding on the one run of 3 feet stones, keeps it going steady twenty hours out of the twenty-four. We have heard of you starting a new mill at Colburn, some 12 miles from us, and that it was not doing well; if this is the case it is in the bad management of it, as your mills, run with any degree of care, will grind as satisfactorily as any mills can. We have not had any expenses in repairing since we started, now about one year; do not try to fill orders for flour in LaFayette, nor could we if we tried. R., F. & BRO. Under date of February 22d, they write:--The note came to hand in due time, and properly cancelled. The custom grinding will reach about 4,000 bushels this month; how will that do? Mr. G. L. Kemp of Frankfort was here, he says their mill is doing well and giving satisfaction. Would like to see your establishment again; will call on you some time before long if nothing prevents. Yours, REDENBO, FRETZ & BRO. Self-Tramming Mill Irons. FOUNTAIN MILLS, Logansport, Ind., March 28, 1872. MESSRS. NORDYKE, MARMON & Co.--_Gents_:--In regard to your burrs and all other work I purchased of you, I will say it is the best I ever saw or used. The stones were in both standing and running balance; that is the first run I ever started that was so to perfection. I haven’ much to say, except when I want mill works, you are sure to get my orders. You have so far satisfied me in quality and prices. I will say I never dealt with fairer dealing men than you, gentlemen. Yours, truly, JACOB MYERS. Under date of April 18th, 1872, Mr. Myers writes again. FOUNTAIN MILLS, 3 miles S. E. from Logansport. _Sirs_:--I thank you a thousand times for making me acquainted with the self-tramming driving irons; they are the best improvement on mill burrs I ever saw. The spindle is always in perfect tram with the face of the runner, and it is no trouble at all to test and keep it in running balance. The stone keeps in better face and I do not have to dress my burrs half as much. It is just what we have been needing. I can make a bigger yield and clearer flour and grind more per horse power. It is astonishing how smooth the stone runs and evenly it grinds. In the States of Pennsylvania, Ohio and Indiana, by actual count, I have run and managed twenty-seven run of stones, and I have not stated to you anything but what I can show here to any one. I sent you Mr. Ringer, or he probably would not have found you out, I believe he ordered a pair of 42-inch stones with the self-tram irons. It gives me pleasure to recommend a good job. Yours, as ever, JACOB MYERS. Three 30 Inch Pulley Mills. WHITESTOWN, Ind., Jan. 11, 1869.
