On returning to America, Dr. Hayes extended his travels through this country, and in 1874, with an eye to business and pleasure, went to California. Here he soon became acquainted with John W. Mackey, the Bonanza king, and other prominent financiers on the coast, and as a result formed a partnership with J. M. Walker, a former partner of Mackey, under the firm name of Hayes & Walker. As a member of this firm, and as an associate with Mackey, Mr. Hayes, during the next three years, did an extensive banking and brokerage business, handling a vast amount of money, and reaping handsome profits, which enabled him, a little later, to buy largely of the stock of the Bonanza mines, which were then pouring a steady stream of wealth into the laps of their owners. Becoming convinced that this would not continue, and that other mining properties were more desirable, he sold out his interest, and after a long investigation bought outright the Red-Hill gravel mines, in Trinity county, California. This purchase, which includes eleven hundred acres of land, in which are located seven mines, and extensive water rights, upon which in that country the value of a gold mine largely depends, makes Mr. Hayes the sole owner of by far the largest and most valuable mining property held by a single individual in the state of California, and establishes his place among the few who have been able to seize and hold the glittering prize for which so many have striven since the western slope began to yield its treasures. While thus seeking his fortune elsewhere, Mr. Hayes has retained his residence in Alton and his lively interest in all that concerns the town and state. The homestead upon which he was born is his, and he makes it his home during the summer. He has expended a large amount in improving it, a barn costing fifteen thousand dollars being among the latest additions. When the house, which he has planned to match it, is erected, the establishment will be one of the finest in the state. In 1876, 1877, and 1878, Dr. Hayes represented Alton in the legislature. He married, in 1877, Jessie B. Benjamin, daughter of E. M. Benjamin, Esq., of San Francisco, a relative of Judah P. Benjamin, of Louisiana, and a lady of rare literary attainments and social accomplishments. Their only child--Lloyd Benjamin Hayes--was born May 21, 1880. With so much success behind him, Mr. Hayes is still a young man, as cheery and active and energetic as when he first left New Hampshire. He has an extensive knowledge of the world, a wide circle of acquaintances among those who shape the politics and business of the country, and hosts of friends who have been won by his unfailing good nature, liberality, and courtesy. He is pledged, when he has done making money, to come back to New Hampshire and spend it. HON. GEORGE COGSWELL, A. M., M. D. BY JOHN CROWELL, M. D.
