Two prominent citizens passed away from earth during the year 1861. One of these, Augustus Sawers, Esq., was during the previous year Mayor of the town, had some years previously founded the Examiner newspaper, and was for a time its Editor and Proprietor. For a few years previous to his death he took an active part in politics, and had warm friends and strenuous opponents. "He was possessed of a good physical constitution, a vigorous and cultivated mind, a quick perception, and a happy facility in expressing his views, either by speaking or writing." His decease occurred on the 6th of August, 1861, in his 42nd year. His remains were interred in the Little Lake Cemetery.
