Lake Huron is the next in succession and the second in magnitude of these inland seas. The outline is very irregular, to the north and east formed by the Canadian territory, to the southwest by that of the United States. From where the Channel of St. Mary enters this lake to the furthest extremity is 240 miles, the greatest breadth is 220, the circumference about 1000; the surface is only 32 feet lower than that of Superior; in depth and in pure transparency the waters of this lake are not surpassed by its great neighbor. Parallel to the north shore runs a long, narrow peninsula called Cabot Head, which, together with a chain of islands, shuts in the upper waters so as almost to form a separate and distinct lake. The Great Manitoulin Island, the largest of this chain, is seventy-five miles in length. In the Indian tongue the name denotes it the abode of the Great Spirit,[123] and the simple savages regard these woody shores with reverential awe. To the north and west of Lake Huron the shores are generally rugged and precipitous; abrupt heights of from 30 to 100 feet rise from the water's edge, formed of clay, huge stones, steep rocks, and wooded acclivities; further inland, the peaks of the Cloche Mountains ascend to a considerable height. To the east, nature presents a milder aspect; a plain of great extent and richness stretches away toward the St. Lawrence. Many streams pour their flood into this lake; the principal are the Maitland, Severn, Moon, and French Rivers; they are broad and deep, but their sources lie at no great distance. By far the largest supply of water comes from the vast basin of Lake Superior, through the Channel of St. Mary. Near the northwestern extremity of Huron, a narrow strait[124] connects it with Lake Michigan in the United States; there is a slight difference of level between these two great sheets of water, and a current constantly sets into the southern basin: this lake is also remarkable for its depth and transparency.[125] At the southern extremity of Lake Huron, its overflow pours through a river about thirty miles in length into a small lake; both lake and river bear the name of St. Clair.[126] Thence the waters flow on, through the broad but shallow stream of the Detroit, until they fall into Lake Erie thirty miles below; on either side, the banks and neighboring districts are rich in beauty and abundantly fertile. Lake Erie is shallow and dangerous, the anchorage is bad, the harbors few and inconvenient. Long, low promontories project for a considerable distance from the main land, and embarrass the navigation; but the coasts, both on the Canadian and American side, are very fertile.[127] Lake Erie is about 265 miles long, and 63 wide at its greatest breadth; the circumference is calculated at 658 miles; its surface lies 30 feet below the level of Lake Huron.[128] The length of the lake stretches northeast, almost the same direction as the line of the River St. Lawrence.
