s Vineyard, No Mans Land, and Block Islandare but portions of the extreme terminal moraine whose backemerges at these points from the water. Cape Cod, fromPro\ancetown to Woods HoU and the Elizabeth Islands, is asimilar remnant of a vast moraine formed after the ice-fronthad withdrawn a short distance to the north. Indeed, thewhole of Plymouth and Barnstable counties is made land,as really as that of the Back Bay in Boston, only in the onecase the earth was dumped, day by day, from the laborerscart, and in the other year by year, from the melting frontof the continental ice-sheet.

Thethree hundred and sixty lakes of Plymouth township arenothing else than a cluster of kettle-holes. Manomet Hill,southeast of Plymouth, is not a mountain which has beenthrust up by convulsive agencies, nor yet a remnant of a par-tially eroded plateau, but a glacial deposit, hundreds of feetin heierht and manv miles in extent. From the fact of itsrunning nearly at right angles to the backbone of Cape Cod,Manomet Hill is spoken of by some as a medial moraine.But it is doubtful if it is necessary so to regard it. The re-treat of a glacier, like the retreat of an army, is determinedin part by the nature of the opposing foe. In the presentinstance there
