We have already explained the reason which underlies the comparatively moderate speed of these ships, and mentioned that the question of economical steaming was at the root of the matter. As an example we might quote the case of the _Majestic_, belonging to the same line, as an instance. This vessel consumes 316 tons of coal per day to get a speed of 19 knots; the _Baltic_, a vessel nearly twice and a half the size, requires only 260 tons of fuel a day for her 16½ knots. And so we come to those two leviathans which form, without exception, the most extraordinary, the most massive, the fastest, and the most luxurious ships that ever crossed an ocean. Caligula’s galleys, which were wondrously furnished with trees, marbles and other luxuries which ought never to desecrate the sweet, dignified character of the ship, were less sea-craft than floating villas exuding decadence at every feature. There are some characteristics of the _Mauretania_ and _Lusitania_, with their lifts, their marbles, curtains, ceilings, trees, and other expressions of twentieth century luxury, which, while appreciated by the landsman and his wife, are nauseating to the man who loves the sea and its ships for their own sakes, and not for the chance of enjoying self-indulgence in some new form. But all the same these two Cunarders are ships first, and floating mansions only in a secondary sense. They are even more than that: they are ocean-greyhounds of a new breed with a pace that surpasses any other of the mercantile sea dogs.
