• “Y., where he read and practiced law until he came to Janesville, in 1855. While a resident of Cortland Co., he took a lively interest in political afiairs, and, while pursuing his legal studies, he purchased the Cortla,nd County Whig, which he edited with ability and earnestness for six years ; at the expiration of this period, the young editor sold it out and gave his entire time and energies to his profession ; shortly after his admission to the bar, much to his surprise, he was nominated to Congress by the Whig Convention in 1846 ; owing to the political complexion of the district, many believed -that the nomination was only an empty honor, but, contrary to general expectation, Mr. Conger was elected to the XXXth Congress, and was re-elected in 1848, although his opponent was his old preceptor,, and one of the ablest and most popular men in the district ; after serving two terms in Congress, he gave his undivided attention to his profession, allowing nothing to divert him from the pursuit of his life ; after twenty-five years' experience as an attorney, a ripe scholar, a well-trained lawyer, an honest man, he was elected Ju'lge of this circuit in 1870 ; re-elected in 1876.”
