In September, 1835, near the close of his twentieth year, he graduated with high honor to himself and the university, then under the long successful presidency of the Rev. R. H. Bishop, D.D., a learned and venerated Presbyterian clergyman, who had early been induced to migrate from Scotland to the Northern United States by the solicitation and in the company of a renowned divine, John Mason, of the Scotch Presbyterian Church in New York, who at that time brought over a very useful and famous little clerical colony to this country.

Young Dennison then immediately returned to Cincinnati, and there commenced the study of law in the office of Hon. Nathaniel G. Pendleton (father of the Democratic candidate for the Vice-Presidency) and Stephen Fales, one of the most eminent lawyers of the West, in his youth a classmate of Daniel Webster at Dartmouth College and always his intimate personal friend. Completing his legal studies and admitted to the bar, he began the practice of his profession in his native city. Soon afterwards he married the beautiful and highly-educated daughter of William Neil, of Columbus (the State capital), a famous and extensive mail-contractor throughout the Northwest, whose name was very familiar to travellers and newspaper-readers twenty or thirty years ago, in the days of stage-coaches, when railroad enterprise was in its infancy at the West.

In 1840 he formed a law-partnership with the once famous, but now infamous, Albert Pike, poet, jurist, and rebel general, Indian savage by adoption and taste, leader of scalping-parties, &c. In the execution of that arrangement he removed to Little Rock, the capital of Arkansas. But the conditions—moral, intellectual, social, and political—by which he found himself there surrounded induced him, after a brief residence and experience, to terminate the connection and return to Cincinnati, where he resumed his professional business. In 1842, at the earnest solicitation of his father-in-law, he removed to Columbus, which became thenceforth his home. He was made solicitor of the Clinton Bank, of that city, then president of the Bank of Columbus; and he finally accepted the entire management and control of all the vast mail-contract and post-road business of Mr. Neil throughout the region between the Ohio and the great lakes.

In politics Mr. Dennison was an original Whig. Throughout the existence of that party organization he was a firm, consistent, and zealously-active member of it. In 1847 he was elected to a two-years term in the Ohio Senate. He next served as president of the Columbus & Xenia Railroad until 1859, when, having been chosen by the Republican party Governor of the State, he resigned his position in connection with corporations. The great rebellion found him commander-in-chief of Ohio. He immediately organized and placed at the disposal of the Federal Government seventy thousand troops, and in offering them gave to George B. McClellan and William S. Rosecrans their first commissions as general officers.

Governor Dennison is a working business-man. He is an impressive orator, tall in person, of courtly but winning manners. He is a good specimen of a Christian gentleman, a devoted member of the Protestant Episcopal Church.

Mr. Dennison, immediately upon entering the precincts of the postal bureau, commenced the study of the peculiar as well as intricate business of the department. His active mind, tact, and general knowledge soon mastered many of its intricacies, and, with a precision which surprised the more knowing ones of the office, arranged and alphabeted its business in such a manner as to facilitate operations and lessen actual labor. By this time Governor Dennison is, no doubt, quite familiar with the business of a post-office.

MAILS TO CHINA AND JAPAN.

One of the most important postal arrangements under this gentleman’s administration is the establishing by steamships a postal communication with China and Japan. Congress passed a law, February 17, 1865, authorizing the postmaster to contract for such conveyance. The tender of “The Pacific Mail Steamship Company,” the only one offered, was accepted and engaged for the service. The compensation therefor is $500,000 per annum for the performance of twelve round trips between San Francisco and Hong-Kong, China, touching at Honolulu in the Sandwich Islands, and Kanagawa in Japan.

This is one of the greatest events of the day, and inaugurates a new era in the commerce of our country. Unless the United States, however, unites all her great advantages and brings them to bear upon her foreign relations in such a manner as to place her commerce on a footing with that of other nations, the mere fact of a new era with these is simply a postal experiment. It is for us to become masters of the commerce of the world; and with this line of steamers regularly established, and the completion of the Pacific Railway, there is nothing to stand in the way of success.

Postmaster Dennison, taking this view of it, says, in his annual report, 1864,—
