The acceptance by the English Government of the Cunard company’s bid for the contract for carrying the mails to America resulted in putting afloat, in 1840, the Acadia, Britannia, Columbia, and Caledonia. The first vessels of the Cunard line were all wooden paddle-wheel steamers, with engines by Napier, of Glasgow, of the usual side-lever class; the return-flue boilers and jet-condensers were used, the latter holding their place for many years to come, though surface condensation had already appeared as an experiment. The company was to carry the mails fortnightly between Liverpool, Halifax, and Boston, regular sailings to be adhered to, and four vessels to be employed, for the sum of £81,000 ($400,000) per annum. The contract was made for seven years, but was continued from time to time for forty-six—no break occurring in this nearly half-century’s service, when the Umbria—November 4, 1886—was the first ship in the history of the company to leave Liverpool on the regular day of sailing for America without mails. This break, however, was but momentary, and the line almost at once resumed its ancient duty. The Britannia was the first of the fleet to sail; and, strange to say (from the usual seaman’s point of view), Friday, July 4, 1840, was the day selected. She arrived at Boston in 14 days and 8 hours, a very successful passage for the time. It must have required considerable moral courage in the projectors to inaugurate such an undertaking on a day of the week which has been so long on the black-list of sailor superstition, notwithstanding it had the advantage of being the anniversary of the Declaration of American Independence. The success of this line ought certainly to rehabilitate Friday to a position of equality among the more fortunate days, though it will be observed that none of the transatlantic lines have yet selected it as a day of sailing. The Britannia, which was representative of the quartette, was of the following dimensions: Length of keel and fore rake, 207 ft.; breadth of beam, 34 ft. 2 in.; depth of hold, 22 ft. 4 in.; mean draught, 16 ft. 10 in.; displacement, 2,050 tons; diameter of cylinder, 72-1/2 in.; length of stroke, 82 in.; number of boilers, 4; pressure carried, 9 lbs. per sq. in.; number of furnaces, 12; fire-grate area, 222 ft.; indicated horse-power, 740; coal consumption per indicated horse-power per hour, 5.1 lbs.; coal consumption per day, 38 tons; bunker capacity, 640 tons; cargo capacity, 225 tons; cabin passengers carried, 90; average speed, 8.5 knots. It will thus be seen that these ships were not an advance upon the Great Western, but were even slightly smaller, with about the same coal consumption and with rather less speed.
