In 1873 this Company added two magnificent screws to their fleet, the _City of Chester_, of which an illustration will be found on the following page, and the _City of Richmond_, each of 4700 gross, or 3000 net register tonnage, and 800-horse power. These vessels were built by Messrs. Caird and Co., of Greenock, and by Messrs. Tod and MacGregor, of Glasgow, and are each 453 feet 6 inches in length over all, with a beam of 43 feet, and a depth of hold of 36 feet. They are spar-decked, have iron masts and solid iron bulwarks, and they are ship-rigged. In midships, there are long rows of centre and side houses, for a portion of the passengers and crew, and where accommodation is likewise afforded for the steering gear which is wrought by manual labour or steam power. There are also “the galley-saloons,” providing cooking apparatus sufficient for 1500 persons; while five of the side houses are devoted to the purpose of male and female hospitals. The engines of these vessels are compound with inverted cylinders and surface condensers; the large cylinder being 120 inches, and the smaller one 76 inches in diameter; the length of stroke of the piston is 5 feet; and their speed on trial was 16 knots an hour.[233] [Illustration: S.S. “CITY OF CHESTER.”] [Sidenote: _City of Berlin_, 1875.] But the Inman Company has recently launched from the yard of Messrs. Caird and Company a still larger and more magnificent vessel, the _City of Berlin_, being the longest and perhaps the largest merchant steam-vessel afloat, the _Great Eastern_ alone excepted. Her dimensions are: length over all, 520 feet; breadth 44 feet; and depth to spar deck, 37 feet; her gross register is 5500 tons; she is supplied with two direct-acting high and low pressure engines (compound condensing) of 900 nominal, but indicating, as proved on trial, 4799 horse-power; her cylinders being 120 and 72 inches diameter respectively, with a piston stroke of 5 feet 6 inches; she has twelve boilers and thirty-six furnaces; and she has accommodation for 202 first-class passengers, and 1500 intermediate passengers and emigrants.[234] A list of the Inman Company’s vessels on the 1st of January, 1875, will be found in the Appendix.[235]
