The improvements in the character of the accommodations have not been greater than the improvements designed to reduce the dangers of the transatlantic trip to a minimum; they are found in the structure of the hulls, the engines, and the boilers; in the apparatus of navigation; in the numbers and discipline of the crews, and in the appliances for life-saving, such as rafts and life-boats. The old ships of twenty years and more ago were built on the lines of sailing vessels, and a poop extended with scarcely a break from the fo’c’s’le to the quarter-deck. When a sea came on board it was held as in a sluice between the high bulwarks and the poop, swashing fore and aft with the pitch of the ship, until it drained off through the scuppers. Most of the state-rooms were then situated below the main deck, and after such a sea they were likely to be flooded; many old passengers will remember how frequent an occurrence it was to find their cabins inundated. This was the least mischief it did, and when several seas were shipped in rapid succession, the vessel was in danger of foundering. The modern steamer is much better protected from incoming seas, and the main deck is completely covered in, instead of the bulwarks there is a simple rail and netting, and any water shipped flows overboard as quickly as it comes on board. But the greatest improvement of all in the direction of safety is the system of bulkheads and double bottoms introduced by the builders of the City of New York and the City of Paris. For many years past it has been the custom to divide all steamers by transverse bulkheads into so-called water-tight compartments, the purpose of which is to increase their buoyancy and stability in case of collision. The Etruria, the Umbria, the Britannic, the Germanic, and the Arizona have nine compartments each. Excellent as the theory is, the feeling of everybody acquainted with the subject has been distrustful of the manner of its application, the chief objection being the inadequacy of the number of subdivisions. Sometimes, as when the Arizona ran into the iceberg, the bulkheads have saved the ship, but in other cases they have been of little or no use, as in the case of the Oregon. The Oregon was divided into ten compartments, but she sank in a few hours after her collision with a coal schooner off Fire Island light. The compartments have invariably proved useless when the ship has been struck amidships with sufficient force to open her engine and boilers to the sea, though when the weather has been calm and the injury forward or astern, they have kept her afloat.
