across the highway the hill is found to rise abruptly some 
20 feet above the plain to the true summit, on which Hateh's 
Rock (Fig. 23) stands. The plain is here at least 300 feet 
wide; and at all points, save where it has been cleared for 
cultivation, it is strewn with bowlders. From this terrace the 
view seaward is broad and unobstructed ; and if the sea has 
ever stood at this level since the drumlin was formed, its 
storm waves must have broken with such resistless force against 
the banks of till as to require only a short time to carve this 
broad platform. 
Several of the lower drumlins of this region, which show no 
terraces—Green, Hoop-Pole, and Mann Hills—are so flat-topped 
as almost to suggest that their original summits have been 
worn away by the sea or some agent of horizontal erosion. 
The lowest terraces on the drumlins consist chiefly and the 
upper ones to a very limited extent of modified drift, being, 
properly, narrow, fringing sand plains. But that the drumlins 
of this region also exhibit many true terraces of erosion, and 
that these are in many cases of such magnitude as to profoundly 
modify the normal contours of the hills, there can be no doubt 
or question. Concerning the origin and real significance of the 
cut terraces, however, there is still room for the widest differ- 
ence of opinion. As stated in the general description of the 
topography (page 7), I at first regarded these terraces as true 
shore-lines, and for the most part as marine shores, finding in 
them evidence of an important postglacial elevation of this 
coast. But a more extended and critical study of these features 
since the printing of this work began has convinced me that, 
as already pointed out, they lack the essential characteristics of 
true shores. They are not only deficient in continuity and 
uniformity of level; but it is further impossible to regard them 
as marine shores, because, with rare exceptions, like Booth 
Hill, they are on the southwest sides of the drumlins and do 
not face the sea; or as the shores of temporary lakes, because 
they are often, as in the Village of Hull and on the World’s
