must remain; the substantial benefits conferred on mankind must remain; the path opened to the golden gates of the west must remain; the flag of the country still fly along its fortified line, and the great tide of emigration roll through its avenue for ages. If Humboldt be the Nestor of scientific travellers, and Audubon the interpreter of nature, Col. Fremont is the Pathfinder of empire. WILLIAM M. GWIN Was born in Sumner county, Tennessee, in 1805. His father, the Rev. James Gwin, was a distinguished divine in the Methodist Episcopal church, and one of its founders in the West. He was for fifty years the intimate and confidential friend of Gen. Jackson, and chaplain to his army during the late war with England. Dr. Gwin was graduated at Transylvania University, in Kentucky, and practised his profession, with eminent success for several years, in his native state and Mississippi. He relinquished his profession in 1833, and was appointed, by Gen. Jackson, Marshal of Mississippi,—an office which he filled until after the election of Gen. Harrison to the presidency, when he became a candidate for congress, and was elected by a large majority. He was remarked, during the session, as a ready, forcible debater, and was renominated by his district with great unanimity, but declined running, owing to pecuniary embarrassments incurred while he held the office of marshal, and brought about by the paper money system, which involved Mississippi in bankruptcy, and especially the public officers, who, like Dr. Gwin, had been induced, under the decisions of the courts, to take this irresponsible paper in payment of executions. In 1846, Dr. Gwin removed to New Orleans, and was soon after appointed commissioner to superintend the erection of the custom-house in that city, destined to be one of the largest public edifices in the country. From this position he retired on the election of Gen. Taylor to the presidency, and emigrated to California, where he engaged actively in organizing a state government. He was elected a member of the convention from San Francisco, and bore a prominent, influential part in its debates and proceedings, which resulted in the present noble constitution. The importance of these services were duly recognized by the people of California, and they testified their regard and confidence in conferring on him the dignity of a United States senator. He will have it in his power to do much for the new state, and we feel assured she will find in him a resolute champion of her rights. THOMAS OLIVER LARKIN.
