springs of great strength are worked to advantage, near lakes Ontario and Michigan. Timber trees in great variety and of valuable sorts, give a rich border to the shores for thousands of miles. Of these, the white oak, burr oak, white pine, whitewood or tulip tree, white ash, hickory and black walnut, are the most valuable. They are of noble dimensions, and clothe millions of acres with their rich foliage. Nowhere else on the continent are to be seen such abundance of magnificent oak, and the immense groves of white pine are not excelled. Heretofore little esteemed, the great tracts of timber convenient to lake navigation and to the wide treeless prairies of the plain, are destined soon to take an important place in the commercial operations of the interior. Already, oak timber, for ship-building and other purposes, finds a profitable market in New York and Boston. The great Russian steamship "General Admiral," was built in part from the timber of the lake border. A great trade is growing up, based on the products of the forest. Whitewood (Diriodendron tulipifera), oak staves, black and white walnut plank, and other indigenous timber, are shipped, not only to the Atlantic cities, but to foreign ports. The lumber yards of Albany, New York, Philadelphia, as well as those of Chicago, Milwaukee, Detroit, Toledo, Cleveland and Buffalo, receive large supplies from the pineries bordering the great lakes. Cincinnati and other Ohio river cities, receive an increasing proportion of pine lumber from the same source. These great waters are also, as is well known, stocked with fish in great variety, whose fine gastronomic qualities have a world-wide reputation.
