In rivers and crowded harbors it is often impossible to follow the rules of the road; and sometimes even at sea the officer of the deck of one vessel discovers that the other is not heeding the rules. Then the steam-whistle is used to tell the other vessel what the first is doing. Thus, one whistle means “I am going to the right”; two whistles mean “I am going to the left”; and three whistles mean “I am backing”; while a series of short toots means “Look out for yourself; get out of the way!”

There is one class of vessels which is most annoying to those who direct the course of large steamers. These are small fishing-vessels. On the Grand Banks of Newfoundland, on the coast of Spain, and on the coasts of China and Japan big fleets of these little vessels are found at all times. They show no lights at night, preferring to save the expense of oil, and take their chances of being sent to the bottom; but when they see a big ship rushing down upon them, they light a torch and flare it about. Often they pay for their folly with their lives. The torch is seen too late, or not seen at all, and the great iron bow of the steamship crushes into the frail little craft, perhaps cutting her clean in two; and the unhappy fishermen sink into the foaming wake of the churning propellers, leaving not a soul to tell their wives what became of them.

ELECTRIC-LIGHT SIGNALS AT SEA: ARDOIS SYSTEM.

Signaling with lights is principally of use to men-of-war, where, also, lanterns hung in the rigging in a particular order have a definite significance. For long-distance signaling the best system is that invented by Lieutenant Very, U. S. N. These night-signals “consist of a white, a red, and a green star, each fired into the air from a pistol, so that by firing one, two, or three of them in quick succession and in different orders, with a pause between the groups, different letters or signal numbers can be made until a sentence is complete.” They can be easily read from vessels twelve miles away. For nearer work the system of the Spanish navy officer, Ardois, which consists in flashing and extinguishing, by means of a switchboard on deck, a series of red and white electric lamps in the rigging, serves very well; and close at hand a signal-man waves an incandescent electric bulb by night as he would a flag by day.

THE “VERY” ROCKET-SIGNAL AT SEA.

It is, however, when the land is approached that the sailor’s perils become menacing. Here Old Neptune is still a match for us when he asserts himself. Nevertheless, we must go upon the restless waters, and must risk a contest with their power along the coasts, where the ocean’s line of battle may be said to be. Therefore, every effort has always been made by men on land to be of aid to their brethren at sea by erecting beacons to guide them by night as well as by day, by marking the channels, so that hidden shoals, rocks, and obstructions may be avoided, and by contrivances to save life and property when the fury of the gale renders seamanship futile, and the noble ship is cast away in the surf thundering on some wild shore, to break up in a few hours.

What could be more humiliating to our pride, as well as terrifying to our hearts, than such a scene as that at Samoa, in 1889, when a whole fleet of ships, including powerful men-of-war, was wrecked while at anchor in the beautiful harbor of Apia. Of small use, then, were all their charts and lighthouses, buoys and breakwaters!
