To obtain a proper conception of this plan, it
is necessary: to advert to geological events, in
this part of the country, whose effects are very
striking. The. whole Country takes an impress,
in some degree, from the great throe which
workedxmt a passage for' the Niagara, through
seven miles of solid rock, seyering, at its outlet,
the ;;§pe,at coronal ridga, at its highest point of
elevation. Nothing, we think, is more evident
to, observer, in tracing oùt the Kienuka
plateau, than the evidences which exist of Lake
Ontario having washed its northern edge, and
driven its waters against: its crowning wall of
limestone. The,fury cf the waves;■ forced,in to
the line of junction, between the solid limestone
and fissile sandstone, has broken up and removed
A e l l a t t e f j fill the’overlying rock, pressed' by its
own gravity, has been split, fissured or otherwise
disrupted, and often slid iif-vasL solid masses
down the ragged precipice. Kienuka offers one
of the most striking instances of . this action.
The fissures made in the rock, by the partial
withdrawal of its support, assume the size of
cavern passages; they penetrate, in some instances,
under other and unbroken masses of the
superior stratum, and are, as a whole, curiously
intersected, forming .a vast .reticulated area, in
which large numbers of men could seek shelter
and security. /- ', '•

At this point, heavy masses of the limestone
