Rock City.—The "City of Rocks" is situated in Ottawa county, about 3 miles southwest of Minneapolis, on the opposite side of the Solomon valley. Originally the city consisted of several hundred round or oval shaped rocks. Of this number perhaps one-half are perfectly preserved, while the remainder are slowly disintegrating, yet all show the original spherical shape. These rocks are a light sandstone, in thin layers or shales, and vary in size from 2 to 15 feet in diameter, and from 2 to 12 feet in height. They belong to the Cretaceous period and got their shape from the action of the water at a time when an inland sea covered that portion of Kansas. A similar formation is to be found in Lincoln county, which adjoins Ottawa on the west, but the specimens are not so numerous nor in as good a state of preservation.
