The paddle steamer Puritan is another example of the very great progress made since the days of the Clermont, and is also a marked advance in many ways on the Bristol, which was the wonder of a few years ago; and another noted case is the steamship Columba, built for service on the Clyde.

The first steamships to cross the Atlantic from England were the Sirius and Great Western,[13] names never to be forgotten. The Great Western was built at Bristol, England, and completed in the year 1838. She was 212 feet long, 35 feet 4 inches broad, and 1,340 tons burden, and had engines of 450 nominal horse-power. She did the voyage from Bristol to New York in 15 days. The time of her quickest passage, given in the table on page 80 as 10 days, 10 hours, and 15 minutes, is not the actual passage, but is the equivalent of a passage reckoned from Queenstown to Sandy Hook.

In 1840 the Britannia, the first of the Cunard steamers, was put on her station. She was a paddle boat, built of wood, and was 207 feet long. Her speed on service was about eight and a half knots, so that she did the passage in 15 days.

Ten years later the now renowned Inman Line commenced with an iron screw steamer named the City of Glasgow, of 1,600 tons burden, and 350 nominal horse-power, a new departure in both ship and propeller.

It was not until 1855 that the Cunard Company built an iron steamer, and they continued to employ paddle boats until 1862, when the celebrated steamship Scotia was completed.

It is interesting to note, in passing, that the average length of voyage in the Cunard Line, in 1856, from Liverpool to New York was 12.676 days, and from New York to Liverpool 11.036 days.

Thirteen years after the Scotia was built the White Star Company placed on the station two vessels that were very great advances on anything then existing; they were marvels of the ship-builder’s and marine engineer’s skill, and even to-day hold their own in many respects with the most modern ships. That these should compete successfully, and eventually drive off the line such a ship as the Scotia is easily seen by reference to contrasted particulars in the table on [page 78]. The Britannic is a screw vessel 455 feet long; her I. H.-P. on trial trip was 5,400, and at sea is about four thousand nine hundred, or practically the same as that of the Scotia; but the speed on trial was nearly two knots more, and the average of eleven voyages gives a mean of 15.045 knots per hour; while as recently as September, 1890, in her old age, she traversed the Atlantic from New York to Queenstown at an average speed of 16.08 knots. She has compound engines with 4 cylinders, the two high-pressure being each 48 inches diameter, and the two low-pressure each 83 inches diameter, with a stroke of 5 feet. Her consumption of coal will be about one hundred and thirty tons per day, and on leaving port she will have on board, say 1,300 tons of fuel. She can carry a considerable cargo. The weight of her machinery is 1,112 tons. She and her sister ship, the Germanic, were in their day admitted to be all that could be desired; almost as much as was physically possible, and certainly as much as was then possible commercially.
