The _Sailor's Word Book_ is no pamphlet; not in the least the kind of pocket book which once helped hurried British soldiers in a French shop to get fried eggs. It weighs, I should think, seven pounds, and it is packed with the vocabulary which has been built into the British ship during the thousand years and more of her growth. The origin of very many of the words retires, often beyond exact definition, into the cold mists of the prehistoric Baltic, and to the Greek Islands, among the shadows of the men who first found the courage to lose sight of the hills. Commonly they are short words, smoothed by constant use till they might be imagined to be born of the circumstances in which they are known, like the gulls and the foam of the wake. They carry like detonations in a gale. Yet quite often such words, when they are verbs, were once of the common stock of the language, as in the case of "belay," and it has happened that the sailor alone has been left to keep them alive. Dr. Johnson seems not to have known the meaning of the verb "to belay" among the other things he did not know but was very violent about. He thought it was a sea-phrase for splicing a rope, just as he supposed "main-sheet" was the largest sail of a ship. The _Sailors' Word Book_ would be much more interesting than it is, though greatly heavier, if the derivation of the words were given, or even guessed at, a method which frequently makes the livelier story. We begin to understand what a long voyage our ship has come when we are told that "starboard" is steer-board, the side to which the steering-paddle was made fast before the modern rudder was invented in the fourteenth century. Skeat informs us that both steor and bord are Anglo-Saxon; in fact, the latter word is the same in all the Celtic and Teutonic languages, so was used by those who first cut trees in Western Europe, and perhaps was here before they arrived to make our civilization what we know it. The opposite to starboard was larboard; but for good reason the Admiralty substituted port for larboard in 1844. Why was the left side of a ship called the port side? That term was in use before the Admiralty adopted it. It has been suggested that, as the steering-paddle was on the right side of a ship, it was good seamanship to have the harbour or port on the left hand when piloting inwards. But it is doubtful if that reason was devised by a sailor.
