Ottawa (One of the largest rivers)

one of the largest rivers of British North America, rises nearly 300 miles due N. of Ottawa city, flows W. to Lake Ten Temiscamingue, some 300 miles, and thence 400 miles S. E., and falls into the St. Lawrence by two mouths, which form the island of Montreal. Its drainage basin has an area variously estimated at from 60,000 to 80,000 square miles. During its course it sometimes contracts to 40 or 50 yards; elsewhere it widens into numerous lakes of considerable size. It is fed by many important; tributaries, the Petewawa, Bonnechère, Madawaska, Rideau, Coulonge, Gatineau, and Rivières du Lièvre and du Nord.

These, with the Ottawa itself, form the means of transit for perhaps the largest lumber trade in the world.
