The following may be considered a fair statement of the cost of producing one ton of pig iron at the Pioneer Iron Co.'s works: 1-1/2 tons iron ore, at $1.50 per ton $2 50 125 bushels charcoal at 7 cents per bushel 8 75 Fluxing 50 Labor 2 50 Incidental expenses 1 00 ------ Cost at the works 15 00 Freight on R. R. and dockage 1 37 ------ Cost on board vessel $16 36 The quantity of wood required for charcoal for both furnaces, is immense. The pioneer furnace requires 2,500 bushels of coal in twenty-four hours; and in blast as they are, day and night, for six months, and at a yield of forty bushels of coal to a cord of wood, it would require 15,000 cords of wood to keep them going. The company has had 120,000 cords chopped this season. This vast consumption of wood will soon cause the country to be completely stripped of its timber. Coal will then come into use. The business of manufacturing pig iron may be extended indefinitely, as the material is without limit, and the demand, thus far, leaving nothing on hand. These facts exhibit the untold wealth of Michigan in iron alone, and point with certainty to an extent of business that will add millions to our invested capital, dot our State with iron manufactories of all kinds, and furnish regular employment to tens of thousands of our citizens, while our raw material and our wares shall be found in all the principal markets of the world. The superior fish, found in such profusion in our noble lakes and rivers, while they afford a highly-prized luxury for immediate consumption, from one of our leading articles of export, and are very justly regarded as constituting one of our greatest interests.
