lively soft and yield easily to the action
of frost and spray. They gradually
crumble away, and the superintendent
rock, being therefore pressed by the
water above and left unsupported be-
low, falls in huge masses from time to
time into the boiling caldron be-
meath. This process continued from
day to day and year to year is con-
tinually altering the appearance of the
falls. .-s5 .as =s1Ee t.e- + -..
The rate of retrogression is a matter
| of much dispute. In fact, from the
causes alluded to, it is very irregular.
The Canadian or Horseshoe fall receded
| five feet during the year 1867, at a
! point of greatest erosion The average,
| for a distance of more than two thirds
of its front, was about three feet. On
| either side of this space its retrogression
varied from two feet to 0. Since then
| (nor nearly three years) their total re-
| PROGRESSION along the f" front" alluded
| to does not exceed six feet. This
would seem to indicate that the present
| rate of retrogression is very irregular
| and less than three feet per annum.
We ascertained those facts by taking
points along the front of the precipice
and driving iron pins into the ground
at various places, in Goat Island and on
the Canadian shore, these pins leach
set consisting of three rods) being set
in line with each other, and with the
points aforesaid, on the verge of the
precipice. Some of the pins were re-
moved, but from those remaining, max
| ing due allowance for the variations in
| the volume of water, we were enabled
to come to the foregoing conclusion.
| The volume of water passing over the
| precipice is much thicker, or deeper,
than it was in 1868 or 1867, yet the
gross height of the water and preci-
pice remains unaltered. This would
seem to indicate that the river bed has
| in the mean time suffered from
erosion. Sir Charles Lyell is of opinion
that the falls recede at the rate of one
mile in 5000 years. Our own investiga-
tions lead US to believe that had Sir
Charles said 10000 years he would be
much nearer the truth. We are in
clined to believe that about 10000
years have now elapsed since they fell
| over the precipice at Queenston, and
that 100000 more will elapse ere they
| will reach Lake Erie, the distance from
their present site to Queenston being
seven miles, and the distance to Lake
| Erie being about twenty. The future
| rate of retrogression will be less than
that of the first.
The retrogression of the American
Falls has been remarkable in one or two
places, but with these exceptions it is
! imperceptible.
In about 5000 years the falls will
have passed the "three sisters'' on the
one side and the site of Mr.. Street, M.
| P, on the other. They will then be at
the site of the rapids, and although the

than at present, yet will the falls be
lower. The gorge or ravine will be
formed along the Canadian shore. Its
| future site is we'll marked at present.
1t is much lower than the bed of the
river elsewhere, although, strange to
say, the waters are much higher than
on either side. The rapidity of the
current neutralizes, to certain extent,
| the tendency of the waters to seek
| their own level. The waters in this
channel, from the rapids, are literally
"piled up in heaps" SO that their aver
| age height is six inches greater than
that of those less subject to the potent
| influence of the currents. As the fric-
ton of the stream grooves out and
| deepens the channel, and as the Horse
/ shoe Fall recedes, the rush of water to
/ the, Canada Falls will become greater
| and greater, and at last the American
Falls will disappear altogether. Three
4 thousand yearsshence there viii be but
| one cataract, and its height will be less
than that os the modern falls.
! Certainly appearances in the face and
surface of the rocks on either side of
the present gorge, seem to indicate that
since the falls came into being their
number from time to time variedsfron
i onesto half q dozen. There are three

in 1873 by Father Hennepin, there

fourth fall thundered over the preci-
pice between the present margin and
the site of the museum. on the Canada
side. Table Rock was a part of the
lprecipice. About eight thousand years
ago the river fell IN one unbroken
sheet, over a aprecipice $50 feet high,

had reached a point about half mile

all this time the site of the town of Mag

river was shallow and broad, and its
current, comparatively speaking, not
very rapid. Goat Island was then un-
der water, anu tne auJacenI SnOreS were
