er-ent character. Up to this point in our investigations some doubt mayattach to the inferences concerning the limits of the greatice-sheet. For, since the ocean everywhere exjjands to thesouth, it may be asked. What certainty is there that itswaters do not cover a belt of glacial deposits still farther outthan those now visible ? No positive answer can be made tothis objection. But, on striking the coast of New Jerseyopposite Staten Island, a fair field of investigation is at onceoffered, and doubt as to the substantial correctness of thedelineation farther on need be no longer entertained. Theline of moraine hills across New Jersey is a direct continua-tion of those forming the backbone of Long Island, andcovering the northern half of Staten Island. Here theyform a sharp line of demarkation between the glaciatedregion to the north and the unglaciated plains to the south.Beocininnc:: at Perth Ambov, the moraine bends northwardthrough Raritan, Plainiield, Chatham, Morris, and Hanover,

At Me-tuchen and at Plaintield the transition is almost as clearlymarked as that between land and water. Before following the terminal belt farther west, whereits characteristics are more or less disguised by the localtopography, we will pause to consider more carefully someof the main characteristics of it as so far traced. That these hills constitute a true moraine is
