Under the new arrangement the Lachine Canal has two distinct systems of locks, giving two entrances at each end. The Cornwall Canal has in the same manner two sets of locks at its lower entrance, and has in other respects been greatly improved. The Beauharnois Canal was not enlarged, but, instead, an entirely new canal on the north shore of the river is being constructed, fourteen miles in length, of the same dimensions as the other enlarged canals, at a cost of $5,000,000. The total cost of the St. Lawrence canals and river improvements west of Montreal has been $29,000,000; of the Welland Canal, $24,000,000; the Sault Ste. Marie, $3,258,025; of the Ottawa and Rideau canals, about $10,000,000; and of the whole canal system of the Dominion about $75,000,000. The total revenue derived from tolls and hydraulic and other rents for the year 1895 was $339,890.49; 2,412 vessels passed through the Welland during the season of 1894, carrying 1,008,221 tons of freight. The quantity of freight moved on the St. Lawrence and Ottawa canals was 1,448,788 tons, and on all the canals over 3,000,000 tons, whereof the products of the forest, 1,077,683 tons; agricultural products, 993,348 tons—the remainder being general merchandise and manufactures.[47] The deepening of Lake St. Peter and other shallow reaches of the St. Lawrence between Montreal and Quebec has created what may be called a submerged canal, fifty miles long, three hundred feet wide, with a minimum depth of 27½ feet, permitting ocean steamers of the largest class now in the trade to discharge their cargoes in the port of Montreal, which is undergoing enlargement at the present time at a cost of many millions of dollars. During the season of 1897 the number of sea-going vessels that arrived at Montreal was 796, with a total tonnage of 1,379,002; 752 of these were steamers, aggregating 1,368,395 tons. The inland vessels numbered 6,384, with a tonnage of 1,134,346. The sea-going steamers were eighty-three in excess of the previous year, with a marked increase of tonnage.[48] During that summer steamships of 10,000 and even 12,000 tons burthen were to be found loading and discharging cargo alongside the wharves of Montreal. The total value of merchandise exported from this port during the year 1897 was $55,156,956. The chief articles of export were as follows:
