equipped with davits that are really up to the minute. The Britannic, owned by the same company to which the ill-starred Titanic belonged, is the biggest British ship ever built, being more than nine hundred feet long and of fifty-three thousand tons displacement. She was to enter the transatlantic trade this fall, but the great European war may defeat this plan. Every safety device that the marine architect can think of has been provided to keep the Britannic afloat; but if, in spite of all this, she is still bent on going to the bottom, her passengers and crew will stand a better chance of getting ashore than any other group of people ever had under similar circumstances.
