THE AGE OF NIAGARA FALLS
The most interesting of Professor spencers papers
was that upon the age OF Niagara Falls. He said
that the first conjecture TO the age Of Niagara
Falls made by Andrew El.icott In l'" VINO
supposed the falls TO be 5000 years old About
lsl Lya estimated the age Of the falls as $500
years. All OF these cary estimates pure con-
lecture. but they correct in supposng that
the gorge had been excavated by the river. The
present investigations have it basis for sur
veys extending nifty years. He wen; on:
A little draining the Erie basin only fell
about 20 feet over the brow Of the Niasara tscaip
.nen; and in Rssni'9de was Just about the size Of
fourth the present volume Of the great cataract.

history of the river the waters Of the three upper
lakes emptled through the Huron basin by way Of
the Ottawa River The height of the falls has adj
yanced several times and owing 10 this change and
the variation in the discharge OF the water
treat OF the falls has varied greatly during chang
Ing episodes The computations OF the age have
been based these changing conditions Of eleva
Ton and downfall OF the river. The first episode,
as before stated. scented small river. with a
total fall OF 200 feet This lasted about 1900 years
Then fe.! another episode. where the height OF The
falls increased from POO 100 feet. succeeded
by the entire drainage of ali the upper Great Lakes
At the same time there were series OF three cas-
cades. the lower gaining the upper. until finally
they were al united In great cataract, much
higher than that OF the present time Subsequently
the waters were raised at the head Of Lake Ontario
so as to bring about the conditions after

Years under nearly the present conditions Thus
