To quickly assess the difficulty of the text, read a short excerpt:
They repose upon the older, ice- worn surface of the solid rocks; and seem to have been deposited in standing, and probably fresh or brackish waters. The boulder deposits hold a position above these clays, and are found disseminated through beds of obliquely laminated sands and clays deposited during an epoch of comparative disturbance. In the depressions of the surface of these beds repose the numerous interior lakes of our State, and the equally numerous beds of peat and marl which remain to ...point out the sites of former lakelets which the agencies of Nature have already filled. During the earlier part of the lakelet history, the elephant and the mastodon inhabited our peninsula, as is certified by the numerous bones and teeth ex- humed from our peat beds. Contemporary with these probos- cideans and with the gigantic, extinct beaver, were the early representatives of our race in Michigan. I am in possession of a flint arrow-head found in the town of Bridgewater, Washte- naw county, in excavating a State ditch, at the depth of seven feet beneath the surface.
