Whilst developing his coal interests, Mr. Rhodes made important discoveries of iron ore, the first being veins of black band ore, very similar to the English and Scotch, though richer. The veins of this ore in Tuscarawas are from five to fifteen feet thick. He also discovered and worked a vein of mountain ore that will also run from five to fifteen feet thick, and is easily mined, one miner being able to mine twenty tons per day after the earth has been removed. Mr. Rhodes spent several months in the ore fields of Scotland and England in 1868, and found the veins there not over two feet in thickness. [Illustration: Yours Truly, D. P. Rhodes] In the Tuscarawas Valley property, Mr. Rhodes has found seven veins of coal, five of which are very good, and he has worked the whole of them. There is also as good fire-clay as any yet discovered, the finest grade being pure sandstone, which stands fire as hearthstones in furnaces better than any other. Shell ore, block ore, and limestone also exist in abundance. The iron enterprises in which Mr. Rhodes is interested are the Tuscarawas Iron Company, formed about 1864, of which Mr. Rhodes is president. This company have three or four thousand acres of mineral land in the Tuscarawas Valley, and the works have a capacity of a hundred and fifty tons per week; also the Dover Rolling Mill Company, of which Mr. Baker is president. It makes all sizes of merchant and small T rail iron, having a capacity of about fifteen tons per day. He is largely interested in a mining company near Massillon, having three engines and three openings there, and can mine a thousand tons of coal per day as soon as the road from Massillon to Clinton is completed. This will be the shortest coal bearing road,--for blast furnace coal--to Cleveland, by fifteen miles, for it connects with the Cleveland, Zanesville and Cincinnati Railroad at Clinton, thence to Cleveland by Cleveland and Pittsburgh Railroad at Hudson. A company was formed and sunk some eight hundred or nine hundred feet, within three miles of Canal Dover, on the line of this company, and found salt water of the very best quality, the water itself being almost strong enough to preserve meat. There is coal within twenty rods of the wells at ninety cents per ton, whereas in Syracuse and Saginaw they have to use wood, at a cost (at the former place) of seven dollars per cord. Mr. Cass, President of the Fort Wayne Railroad, and J. N. McCullough, of the same and of the Cleveland and Pittsburgh Railroad, are heavily interested in the road connections adverted to above. At Fulton, three miles below Clinton, is another coal company in which Mr. Rhodes is interested. This mine yields about three hundred tons per day, and could double that amount if there were sufficient transportation. There are two engines and two openings at this bank.
