new company was called McArthur's Mining Company. The investors in McArthur's Mining Company, besides Alexander McArthur, were Dr. G. M. Peck, Samuel Daskham, and Edward W. Lockwood of New York City. Dr. Peck was chosen president and Alexander McArthur as local agent. The new company erected an engine–room, a coalhouse, an office, and tramways. Their initial investment was also used for machinery and other buildings at the mines. They also constructed a very large wharf on the Detroit River where the coal was taken to. From Detroit the coal was carried by steamers to New York City. The cost of transportation of the coal was more than anticipated and soon it became unprofitable to operate the company. The company was dissolved a year after it started. Briar Hill Iron and Coal Company of Ohio in 1869 through 1870 sent out their representative Charles Gilbert, a practical geologist, to examine the coal region around Corunna, Michigan and the area at McArthur's Mining Company. He began testing for coal by drilling test-holes. Gilbert drilled 56 test-holes of which 46 showed coal deposits in section 23 of Caledonia Township. Henry P. Gilbert purchased from Chauncey Hurlburt on April 1, 1871, some 66 acres of land where these tests were made. He in turn sold an interest in this land in December of that year to other investors, George F. Perkins, John Stambaugh, of Akron, Ohio, and George Todd, of Youngstown, Ohio. The investors opened a slope and to mine coal in 1872. They invested over $90,000 to make the venture profitable, but within a year they went broke. An improvement that this company left behind was a railroad track from the mine to the Corunna Depot. This was a major improvement over horse–drawn and ox–drawn wagons that had been used for some 38 years before. Final history The Corunna Coal Company was then organized for mining coal, fire clay, and other ores on February 26, 1873. They mined from the same vein where mining was started by Alexander McArthur back in 1839. The investors were working with $150,000 for this venture. They were George F. Perkins, of Akron, Ohio; George Todd, of Youngstown, Ohio; and Henry P. Gilbert, Harry R. Gilbert, Thomas Struthers, and John Stambaugh - all of Ohio. The officers were George Todd, President; and Todd Kincaid, Secretary and Treasurer. This new 1873 company had offices both at Youngstown, Ohio, and
