p.2 A new steam-barge, called the William Henry, arrived in port on the 17th, and is now lying at the canal wharf. This vessel was built at Sorel, for Mr. Nunn, Engineer, and is intended to ply between Montreal and Kingston and intermediate ports, up the Rideau and down the St. Lawrence. The length of the William Henry is 92 feet; the breadth of beam 16 feet, and she is of about 20 horse power. In coming up to Montreal, the speed was equal to seven miles an hour. Accommodations are provided for 12 cabin passengers.
British Colonist, June 23, 1841
p.3 On Thursday afternoon, a new barge propelled by the Ericson screw, belonging to Messrs. Murray & Sanderson, arrived in our port from Brockville. We are informed by a gentleman who made the passage in the Ericson, that she ran in smooth water at the rate of six miles an hour, and without any disagreeable motion or noise from the machinery. We saw this boat moving about our harbour yesterday morning, - she ran as far down as the Quebec Barrack, and came up against the current in a much shorter time than could have been expected. Complete success, in our opinion, has attended this experiment and we shall no doubt, see the Ericson propeller in general use on our Canals in the course of another year. It is believed that this boat will not take over a week to perform the trip to Kingston by the Rideau Canal and down by the Saint Lawrence. She was not more than sixteen hours in coming from Brockville to Lachine, a distance of 140 miles. [Montreal Courier]
