The palaeo- lithic implements of France and-England are gen- erally made of flint very compact in grain, which is found in the chalk deposits of those countries. Glossiness of surface may be due in a great measure to long-continued use, and there is but little doubt that chemical causes may also add to its smooth sur- face. Patina is due to the infiltration of certain sub- stances through the beds in which the palaeolith had been deposited, this action partially dissolving the substance of the flint. New Comerstown is situated upon the right bank of the Tuscarawas River, forty miles south of the glacial boundary of Ohio. The latter part of the journey from the north to reach the place is so com- plete a demonstration of the now accepted theory concerning the origin of the terraces along this river, and others similarly situated, that a brief description of it will be profitable. “ The head waters both of the Tuscarawas itself and of the several branches which unite with it before reaching Canal Dover, are all within the glaciated area, thus afford-](https://iiif.wellcomecollection.org/image/b24855820_0033.jp2/full/800%2C/0/default.jpg)
