"I am afraid there are very few, Dick boy," returned the elder man kindly. "I suppose that is somewhat of a disappointment to you. You would have preferred to sail the seas in the days when every small liner carried her guns as a defence against raiders and was often forced to use them, too. But when international law began to regulate traffic on the high seas and the ocean thoroughfare ceased to be such a deserted one pirates went out of fashion, and every nation was granted equal rights to sail the seas unmolested. It was because this freedom was menaced by German submarines in the late war and our privilege to travel by water threatened that our nation refused to tolerate such conditions. A code of humane laws that had been established for the universal good was being broken and we could not permit it. For you must remember that now there are almost as many laws on the ocean as on the land. There are rules for all kinds of vessels, of which there are a far greater variety than perhaps you realize. Not only have we steamships, cruisers, and battleships but we have schooners, barques, brigs, tugboats, dredgers, oil-tankers, turret ships for freight, cargo boats, steam tramps, coalers, produce ships, ice-breakers, train ferries, steam trawlers, fire boats, river boats, harbor excursion boats, coasters, whalebacks, steam yachts, launches and lake steamers. Each of these is carefully classified and has its particular traffic rules, and in addition to these is obliged to obey certain other general marine laws to which all of them are subject, in order that travel by water may be made safe."

"Don't all ships have to be inspected, too?" asked Stephen.

"Yes; and not only are they inspected but to protect the lives of their passengers and crew, as well as preserve their cargo, they must adhere to specified conditions. The number of passengers and crew is regulated by law, as is the amount of the cargo. Ocean liners, for example, must have aboard a certain number of lifeboats, rafts, belts, life preservers, fire extinguishers, lines of hose; and the size of all these is carefully designated. There must be frequent drills in manning the boats; the fire hose must be tested to see that it works and is in proper condition; and in thick weather the foghorns must be sounded at regular intervals. There is no such thing now as going to sea in haphazard fashion and trusting to luck. Everything that can be done for the safety of those who travel the ocean must be done."

He paused a moment, then added:

"And in the meanwhile, that every protection possible shall be offered to ships, we have been as busy on the land as on the water and have established a code of laws to govern our coasts, harbors and rivers. Government surveys have charted the shores of all countries so that now there are complete maps that give not only the coast line but also the outlying islands, rocks and shoals that might be a menace to ships. It is no longer possible for a State bordering on the sea to put up a low building at the water's edge and set a few candles in the windows as was done back in the year eighteen hundred."

Both the boys laughed.

"We can laugh now," assented Mr. Ackerman with a smile, "but in those days I fancy it was no laughing matter. Even with all our up-to-date devices there are wrecks; and think of the ships that must have gone down before charts were available, lighthouses and bell buoys in vogue, wireless signals invented and the coast patrol in operation. I shudder to picture it. Sailing the seas was a perilous undertaking then, I assure you. Even the first devices for safety were primitive. The Argand lamp of 1812 was not at all powerful and the lenses used were far from perfect. Foghorns were operated by hand or by horse power and were not strong enough to be heard at any great distance. Bell buoys were unknown although there were such things as bell-boats which were anchored in dangerous spots and rung by the wash of the waves. There were lightships, too, but more often than not their feeble light was obscured or unnoticed and they were run down by the ships they sought to protect. Altogether there was room for improvement at every point and slowly but surely it came. After the Daboll trumpet, whistle and siren had been tried finer horns operated by steam or power engines supplanted them until now all along our coasts and inland streams signals of specified strength have been installed, a commission deciding just what size signals shall be used and where they shall be placed. There are lighthouses of prescribed candle power; automatic flashlights and whistling buoys; coastguard stations with carefully drilled crews; all regulated by law and matters of compulsion. If men and ships are lost now it is because it is beyond human power to help it."

"There are facts about the water that are impossible to modify," interrupted Mr. Tolman, "and I suppose we shall never be able wholly to eliminate the dangers growing out of them. There are for example silence zones where, because of the nature of air currents or atmospheric conditions, no sounds can be heard. Often a foghorn comparatively near at hand will belch forth its warning and its voice be swallowed up in this strange stillness. Many a calamity has occurred that could only be accounted for in this way. Man is ingenious, it is true, but he is not omniscient and in the face of some of the caprices of nature he is powerless."

Mr. Ackerman rose and stood with his back to the fire.

"And now," went on Mr. Tolman, addressing Stephen and Dick, "I should say you two had had quite a lecture on steamboating and should move that you both go to bed."
