The St. Lawrence seaway

THE so-called St. Lawrence seaway is a proposition now seriously entertained, by which ocean ships may be provided with deep water navigation from the Atlantic Ocean through the great Lakes up to the head waters at Duluth. The depth proposed is from 25 to 30 feet. The cost, according to the figures given in a report of an international board of engineers, is in round numbers $270,000,000. These figures are based upon material and labor costs 80 per cent above pre-war prices and they include a hydroelectric power plant delivering about 1,700,000 horse power, this being a portion only of the potential power, which is estimated at between five and six million horse power.
