About 1850 was the height of steamboat-prosperity on the lakes. There was at that time a line of sixteen first-class steamers from Buffalo to Chicago, leaving each port twice a day. The boats were elegantly fitted up, usually carried a band of music, and the table was equal to that of most American hotels. They usually made the voyage from Buffalo to Chicago in three or four days, and the charge was about ten dollars. They went crowded with passengers, four or five hundred not being an uncommon number, and their profits must have been large. The building of railroads from East to West, such as the Michigan Central and Southern lines, and the Lake Shore and Great Western, soon took away the passenger-business, and the propellers could carry freight at lower rates than those expensive side-wheel boats could pretend to do. So they have gradually disappeared from these waters, until at present their number is very small, compared with what it was ten years ago, while the number of screw-propellers is increasing yearly, as well as that of sail-vessels. Great as is this lake-commerce now, it is still but in its infancy. The productive capacities of most of the States which border upon these waters are only beginning to be developed. If in twenty-five years the trade has grown to its present proportions, what may be expected from it in twenty-five years more? The secession of the Gulf States from the Union, and the closing of the Mississippi to the products of the Northwest, could we suppose such a state of things to be possible, would still more clearly show the value of the lake-route to the ocean. Run the line of 36° 30' across the continent from sea to sea, and build a wall upon it, if you will, higher than the old wall of China, and the Northern Confederacy will contain within itself every element of wealth and prosperity. Commerce and agriculture, manufactures and mines, forests and fisheries,--all are there. THE MAN WHO NEVER WAS YOUNG.
