Not illustrated. 1878 edition. Excerpt: ...cent.; of water in combination 4.8.; metallic iron 44 per cent.; earthy matter, 24.3. The remaining 4 portions of the 10 feet bed, from which the preceding sample was taken, were examined and found to yield different quantities of iron, from 6 to 16 or 20 per cent. It is probably that in working some of the other varieties of ore found on the Company's domain, portions of this 10 feet bed will be found available as furnishing materials to promote the fusion and facilitate the working of the richer descriptions, which do not contain a sufficient quantity of earthy ingredients to produce a good cinder for the protection of the iron in the hearth. No. 4-This sample is from a stratum of iron ore and fire clay found on Fall Creek, at an elevation of about 46f feet above the lower bed of coal, or 1,158 feet above our base line; the bed of materials in which it occurs is 2 feet 6 inches thick, of which 4 inches at the bottom are fire clay, the remaining portion iron shale, intermixed with flattened reniform masses of argillaceous carbonate of iron, and some carbonaceous matter derived from fossil vegetable remains. The whole bed, together with the superincumbent mass of sandstone rock, or fine conglomerate, appears to have fallen from place, and the situation was not therefore favorable for determining the real value of the bed. The sample submitted to experiment was a fair type of the ore in this bed; but it should be added, that all which we could conveniently obtain at this place had undergone a change, and been reduced from carbonate to hydrate. Its specific gravity was found to be 3.2113. It lost of hygrometrio moisture, 3.5 p. c.
