in Canada. and the observations of Mc Kensie tends to prove their identity
about one hundred miles east of lake Superior he observed that "the rocks is
generally now of a dark blue grey" and at Lake Winnipeek. The north bank is black and grey rock."

"He had informed us that the country is granite and although there is much
variety of color in our fragments a great proportion would accord with his
descriptions. This is suggested for the use of future observers."

"The gravel hills to the south of Lake Ontario have been briefly noticed but a
further description may be proper. Of these astonishing monuments we have seen
no place that presents them in more interesting forms than at Montezuma. The
beautiful ridge on which this village stands coincides with the magnetic meridian but those to the south vary to the left from five to twelve degrees. We have not
observed a greater variation however than two degrees in such as are adjacent."

The shape of the hills is various but we believe the principle number may be
comprised within two classes. The highest and most abrupt appear to contain
a greater proportion of coarser materials the ascent at the north end is generally
steep and the greatest height and magnitude of the ridge is near that extremity.
From a side view the pithed Hog backer has been applied. The descent towards
the south is long and gradual though the whole distance will rarely equal two hundred rods. On the north end several ridges the eye may trace the sharpness of the
summit continues down and turns toward the north east for a few rods before it
terminates but the feature is not general."

"It is very rare to find one ridge commence on the southern slope of another. In some places two ridges contiguous side by side and a shallow channel of two or three rods in width extends the whole length like the indentures of a melon. Such
is the hill at Dr. Clarks.

The spaces of level land between the ridges however are very irregular and in some
considerable tracts a solitary ? appears. such is the hill to the north of Montezuma.
We have seen several trees situated not of a greater magnitude than some mounds
in the western county and only distinguishable at first sight by resembling the
longitudinal section of a prolate spheroid."

"The height of the these ridges is very variable we have not estimated any at one ?
feet above the surrounding lands but we think from 40 to 70 feet altitude would include a great number."

" The Leoric class will include those ridges of less elevation which are very straight
and extend for greater distance than the former these ? are remarkably picturesque
on many the summit is to sharp for a road but others are sufficiently broad for this purpose and in some places percentage has broken of there natural turnpikes."

"the islands which are surrounded by the marshes of the Seneca river resemble in
every respect the hills on the adjacent shores. Some of these rise just above the
surface as is much of these bodies of earth and gravel had been sunk in deep water."

In considering this subject it is evident that the first effects of an extension attraction would be perceptible on fluids and that in succession to the most at the
ordinary tides. Detached solids of greater specific gravity than water would acquire
new motion. It is clear however that the strata fastened down by cohesion would
not be obedient to these impressions. In extending our views to such districts as would furnish the greatest gravity of movable matter the craggy mountain on the wave worn shore would first be presented to the river and to the south of such collections
we would look for the most unequivocal traces of the deluge for although the primitive rocks in our county (Cayuga) have been removed from afar and though in several instances we have seen native rocks deposited on heights above the strata from which they were taken.

Yet it is worthy of remark that all these substances are scattered in the greatest
abundance immediately to the south of their native beds. the sand and gravel fills
the hills which rise on the borders of Lake Ontario were doubtless derived from that
great basin."

Admitting this hypothesis the ridge road on the south shore of Lake Erie and Ontario is easily demonstrated. It is known the moon produces a tide of 60 feet in
height. The ridge was on the south shore Of Lake Ontario is situated from 70 to 100
feet above the level of the lake
