amazing rapiddity shoots over the edge of a
solid perpendicular Rock, and Falls (according to
A. Elliotts account) 137 feet -

- for about a mile above the great Fall, there is
a continued succession of Cataracts, some of
them 3 or 4 feet perpendicular, this greatly en-
creases the rapiddity of the current, until it comes
to the edge of the Precipice, over which it dashes -

The River at the Falls is divided by a small
flat Island, of perhaps 250 yards in width, and twice
that number in length - the sides and upper end,
not much elevated above the surface of the River
above the Falls, the lower end, which is on a line
with the Falls, is a smooth perpendicular Rook, I suppose
of about 150 feet high.- The edge of the Rock over
which the water Falls, on the East side of the Island,
, is nearly a straight line,
and the River, on that side, I suppose to be 250 yards
wide, but the Water not so deep as on the West side
