Desoription

2. The Berea sandstone is derived from the Berea grit, a member of the Lower Carboniferous series in Northern Ohio. It is frequently called the Cleveland sandstone, from the name of the firm controlling a number of the quarries. The principal quarries are located at Amherst and Berea. The stone from Amherst is generally light drab in color, very homogeneous in texture, and composed of nearly pure silica. It is very resistant to fire and weathering, and is, on the whole, one of the best and handsomest building stones known. The Berea stone is lighter in color than the Amherst, but sometimes contains sulphide of iron, and is then liable to stain and decompose.

3. The Warerly sandstone, also derived from the Lower Car boniferous series, comes from Southern Ohio. This is a fine grained homogeneous stone of a light drab or dove color, which works with facility, and which is very handsome and durable. It forms the material of which many of the finest buildings of Cincinnati are constructed, and is, justly, highly esteemed there and elsewhere.

4. The Lake Superior sandstone is a dark, stone of the Potsdam age, quarried at Bvs.s Island, Marquette, Mich. This is rather a coarse stone, of medium strength, but homogeneous and durable, and one much used in the Lake cities.

5. The St. Genevieve sandstone is a fine grained sandstone of a delicate drab or straw color, very homogeneous in tone and texture. It is quarried at St. Genevieve, Missouri, and is one of the handsomest of all our sandstones.

6. The Medina sandstone, which forms the base of the Upper Silurian series in Western New York, furnishes a remarkably strong and durable stone, much used for pavements and curbing in the Lake cities.

Other Names.

There is a great variety of names of more or less local application, derived from the appearance of the stone, the use to which it is put, etc., which it would be impossible to classify. The same stone often passes under entirely different names in different localities; and stones entirely different in their essential characteristics often pass under the same name.
