Schroeder Brick & Lime Manufacturing Co. Quarry. Some stone is quarried by the Schroeder Brick & Lime Manufacturing Co. in the town of Shakopee. Most of it is used for lime burning and is said to make a very strong brown lime. The quarry face, 12 to 15 feet deep, shows a series of distinct but uneven beds 6 to 8 inches thick. Most of the rock is dolomite but is interbedded with layers of sandstone, which are used locally for foundations. Though it is useful for this purpose probably it would not pay to excavate it except as a by-product in the manufacture of lime. Both rocks are very porous and show irregular jointing planes. (The Structural and Ornamental Stones of Minnesota, Oliver Bowles, Department of the Interior, United States Geological Survey, Bulletin 663, Government Printing Office, Washington, D.C., 1918, Page 189)
At Shakopee the river alluvium is known to extend over 20 acres to the unusual depth of 30 feet. A dark clay some distance from the river is more plastic than that closer by, and the two are mixed to produce material proper for soft-mud red bricks. Some re-pressed brick are made at the same plant. The [unfired] clay slakes [quality by which a dry lump of clay tends to absorb water and fall to pieces when immersed] in three minutes and has a rather low plasticity [capability of being molded]. It requires 23 per cent of water for molding and shrinks 4 per cent on drying. Its tensile strength [maximum stress it can withstand before breaking] is about 150 pounds to the square inch and is not much reduced if the clay is rapidly dried. The plant has a capacity of about 3,000,000 brick a season. Burning is conducted in a patent 30-arch kiln by what is known as the John G. Boss system. (Clays and Shales of Minnesota, Frank F.
