Estimates of Niagara River's Channel-Cutting Time

MATHEMATICS may be an exact science, but all who deal in its problems cannot be exact. Several at the late American Association in Detroit indulged in calculations as to the time it has taken the Niagara river to cut its channel from Queenstown to the present falls. Their estimates vary all the way from 20,000 years up to 200,000.—Battle Creek Daily for Aug. 23.
