Our afternoon sail was up Detroit River and the St. Clair, threading our way among its many verdant islands and rich shores graced with numerous pretty villages. At 9 p.m. we reached Port Huron and its Canadian opposite neighbor, Sarnia. At this point is the southern outlet of Lake Huron, distant seventy-three miles from Detroit. Sarnia is also the western depot of the Grand Trunk Railway of Canada, while Windsor, facing Detroit, terminates the Canadian Great Western. From Sarnia, passing old Fort Gratiot, over to Port Huron, the railway ferry boat, propelled by the current only, transfers its passengers to the cars of the Grand Trunk line, on Michigan soil, and by a short branch intersects the Michigan Central Railroad, a few miles west of Detroit. For over twelve hundred miles this iron road, fitly named the Grand Trunk, transports our Western products. Entering Lake Huron, with its innumerable islands and almost wilderness shores, our sail through it, of two hundred and seventy-five miles in all, brought us early, on the 2d of August, off Saginaw and Thunder Bays, its western arms, with Presque Isle, the Great Manitoulin Island, bearing north by east; and by noon, we reached Point de Tour, at the outlet of St. Mary's River, three hundred miles from Detroit, lying opposite to Drummond's Island. Point de Tour has but a solitary dwelling, from whose roof rises the light tower. Its inmates are said to have preferred this solitude to the crowded refinement of a New England city. Shortly after, and still coasting the western side, we stopped at Church's Landing, where an enterprising New Englander has built his log houses in the forest, amid the Indians, and drives an active commerce in _raspberry jam_. His trade has prospered, and he had just completed a new and handsome dwelling. Fourteen miles farther brought us to Saut Sainte Marie, or the rapids of the eastern outlet of Lake Superior. Lake Huron is at an average height of five hundred and seventy-five feet above the sea level, and one hundred feet in depth below Lake Superior, with a length in direct line of two hundred and seventy-five miles, from Port Huron to Saut Sainte Marie. Georgian Bay, to the east of the Great Manitoulin Island, is its broad eastern expansion; while, on the west, the Straits of Mackinaw open into the vast expanse of Lake Michigan, extending a length of four hundred and forty-six miles to Chicago. The borders of Lake Huron are sparsely peopled. The primitive forest bends over the lake's clear waters, and surrounds the log cabin or infant settlement with the wigwam and canoe of the Indian half breeds, who are still fishing and hunting round the graves of their ancestors-once the fiercest of all the warrior races that scarce forty years ago as sovereigns roamed its wilds.
