height of over three hundred feet, directly from the water at ordinary level. On the Ohio side there is a flood-plain from fifty to one hundred yards wide and from twenty to thirty feet above low water. Along the west side of this flood-plain is located the river division of the Cleveland and Pittsburg Railroad, along the foot of the high-level terrace. This terrace ranges from sixty-five to eighty feet above low water. Excavations in this terrace to a depth of forty-three feet show it to consist of interstratified sand, fine gravel, and clay in small quantities, all with rare exceptions cross-bedded. Coarse gravel is found at the top of the terrace; but, except for two or three feet on top, only rare pieces of gravel occur of more than one half cubic inch in size. Two small ravines cut through the terrace at Brilliant. A mile below these. Block House Run, and a mile and a half below. Riddle's Run cut through the terrace down to the flood-plain of the river. Otherwise the surface of the terrace is a plain. A half mile of turnpike was built on it, in which the original surface varied less than two feet.

Indian mounds and intrusive burials occur at numerous places on the terrace, but the stratification and cross-bedding of the sands and gravels of it are such that intrusive burials or excavations can not be made without leaving evidence so distinct as to be
