In the Christmas season of 1854 he went with a friend on a visit to Philadelphia and stayed at the house of Philip M. Price, a prominent citizen of that place who was engaged, among other things, in the conveyancing of real estate. It will not be surprising to any one who knew the charm of his society in later life to be told that he became at once a favorite with the older man. The latter was advanced in years, he was anxious to retire from active business. Acting under his advice, Warner was induced to come to Philadelphia in 1855 and join him, and to form subsequently a partnership in legal conveyancing with another young man who had been employed in Mr. Price's office. Thus came into being the firm of Barton and Warner. Their headquarters were first in Spring Garden Street and later in Walnut Street. The future soon became sufficiently assured to justify Warner in marriage, and in October, 1856, he was wedded to Susan Lee, daughter of William Elliott Lee of New York City. But though in a business allied to the law, Warner was not yet a lawyer. His occupation indeed was only in his eyes a temporary makeshift while he was preparing himself for what was to be his real work in life. Therefore, while supporting himself by carrying on the business of conveyancing, he attended the courses of study at the law department of the University of Pennsylvania, during the academic years of 1856-57 and 1857-58. From that institution he received the degree of bachelor of law in 1858--often misstated 1856--and was ready to begin the practice of his, profession. In those days every young man of ability and ambition was counseled to go West and grow up with the country, and was not unfrequently disposed to take that course of his own accord. Warner felt the general impulse. He had contemplated entering, in fact had pretty definitely made up his mind to enter, into a law partnership with a friend in one of the smaller places in that region. But on a tour, somewhat of exploration, he stopped at Chicago. There he met another friend, and after talking over the situation with him he decided to take up his residence in that city. So in 1858 the law-firm of Davenport and Warner came into being. It lasted until 1860. It was not exactly a favorable time for young men to enter upon the practice of this profession. The country was just beginning to recover from the depression which had followed the disastrous panic of 1857; but confidence was as yet far from being restored. The new firm did a fairly good business; but while there was sufficient work to do, there was but little money to pay for it. Still Warner would doubtless have continued in the profession had he not received an offer, the acceptance of which determined his future and changed entirely his career.
