Surprise was a steamboat which operated on the upper Willamette River from 1857 to 1864.

Construction

Surprise was built in 1857 at Canemah, Oregon by Cochrane, Cassidy & Gibson, who had built the James Clinton the year before.^[1] Surprise, reportedly a well-built boat, was 130 ft (40 m), feet long, probably exclusive of the extension of the main deck over the stern, called the fantail, on which the stern-wheel was mounted.^[1] The beam was 22 ft (6.7 m) feet and the depth of hold was 4.6 ft (1.4 m) feet.^[2] The steamer’s registered size was 120 tons, a measure of size, not weight.^[1]

Engineering

Surprise was a sternwheeler, and the wheel was turned by twin steam engines, horizontally mounted, each with bore of 14 in (36 cm) and stroke of 60 in (1.5 m).^[2]

Operations

Surprise was operated on the upper Willamette River by Capt. Theodore T. Wygant.^[1] Other partners in the boat were Absalom F. Hedges, Oregon City merchant, William. C. Dement^[1] & Co., Charles C. Felton, J. Harding, and Robert Patton.^[1] In April 1858, Surprise transported the native American leader Tecumtum, also known as Old John, to Fort Vancouver where he was to be held in custody.^[3]

As of November 1, 1859, Surprise was running under the control of the Upper Willamette Transportation Line.^[4] Other boats controlled by the line were Onward, Elk, and Relief.^[4] In December 1859, the line advertised that one of its four boats would leave Canemeh for Corvallis, Oregon twice a week, and for Eugene City once a week, with freight and passage “at the usual rates.”^[4] Theodore Wygant (b.1831) was the Oregon City agent for the line.^[4]

Disposition

Surprise operated on the upper Willamette until 1864 when it was dismantled and the engines installed in a new steamer, Senator.^[1]
