3. Rivers. The great rivers of North America rise in the central part of the continent 

 and, flowing in different directions, pour their waters into the Arctic, Atlantic, and Pacific 

 oceans. The Mackenzie, the Saskashawan, the St. Lawrence, the Missouri, the Mississippi, 

 and the Columbia, are the principal streams. The Mississippi has the longest course, but the 

 St. Lawrence discharges the greatest volume of water. 



4. Bays and Gulfs. Baffin's Bay, a large sea lying to the west of Greenland, communi- 

 cates with the Atlantic ocean on the south through Davis's Strait. Its northern coast has 

 never been explored, but it probably communicates with the ocean to the north of Greenland, 

 and separates that region from the continent. Barrow's Strait is an outlet on the west, which 

 has been explored to 110° W. Lon. Its termination is unknown. Hudson's Bay is about 

 1,000 miles in length from north to south, by 800 in breadth. It is full of sand-banks, reefs
