Commencing on the east, where the Greenland Sea washes the coast of Labrador, and Hudson Strait leads to the intricate channels communicating with the Arctic Ocean, we have on the first-named coast a low and level region, which rises inland to a considerable elevation, and then once more sinks on the shores of Hudson Bay. West of that bay there is a wide extent of low country, intermixed with numerous lakes and marshes; and then along the Arctic shore is a wild, barren, treeless district, rising at length into the mountainous region of the Arctic highlands. Amid them numerous rapid streams find their way into the Arctic Ocean. Again they sink into the basin of the Mackenzie River, which separates the in from the northern end of the Rocky Mountains. Hence westward to the Pacific is a broad highland region, rising into the lofty range of the Sea Alps. THE SECOND ZONE. THE FERTILE BELT OF RUPERT'S LAND. The next Zone we will consider as commencing at the Gulf of Saint Lawrence. Westward extends an elevated region, rising in many places to a considerable height, and forming the water-shed of the rivers which flow on the south side into the Saint Lawrence, and on the north into Hudson Bay. Proceeding up the Saint Lawrence, we arrive at a great lake district, which embraces Lakes Ontario, Erie, Huron, Michigan, and Superior, to the extreme west. On the north-western shores of that lake we find an elevated district with several small lakes and streams flowing through valleys. This is the water-shed also of two systems. The streams to the east, flowing into Lake Superior, ultimately enter the Saint Lawrence; while those to the west make their way into Lake Winnipeg, the waters of which, after flowing through a variety of channels, fall into Hudson Bay. To the west of this water-shed range the first lake we meet with is known as the Lac des Milles Lacs. Two rivers flow from it, expanding here and there into small lakes, till another expanse of water is reached called Rainy Lake. This in the same way communicates by two streams with the still larger Lake of the Woods, the whole region on both sides being thickly wooded. From the Lake of the Woods flows the broad and rapid Winnipeg River, which finally falls into Lake Winnipeg. This large and long lake is connected with several others of smaller size,--Lake Winnipegoos and Manitoba Lake to the west of it. Into the southern end of Lake Winnipeg flows the Red River, which rises far-away in the south in the United States, taking an almost direct northerly course. Towards the north, about twenty miles from the lake, is situated the well-known Selkirk settlement. To the west of the Red River commences a broad belt of prairie land which extends here and there, rising into wooded heights and swelling hills, with several large rivers flowing through it, to the very base of the Rocky Mountains. As we advance westward we find it extending considerably to the north,
