Echo (towboat)
An indication of changing times was the construction in 1910 by the Shaver Transportation Co. of Portland of its first motor towboat, the 60-foot Echo, powered with a 125horsepower Imperial gasoline engine and placed in charge of Capt. F. G. Wenn and Engineer B. A. Campbell. This firm, which had begun operations with river packets, was turning to the towing business, a field in which it was to gain much prominence in later years.
