Beyond thirty! Romance, adventure, strange peoples, fearsome beasts—all the excitement and scurry of the lives of the twentieth century ancients that have been denied us in these dull days of peace and prosaic prosperity—all, all lay beyond thirty, the invisible barrier between the stupid, commercial present and the carefree, barbarous past. What boy has not sighed for the good old days of wars, revolutions, and riots; how I used to pore over the chronicles of those old days, those dear old days, when workmen went armed to their labors; when they fell upon one another with gun and bomb and dagger, and the streets ran red with blood! Ah, but those were the times when life was worth the living; when a man who went out by night knew not at which dark corner a “footpad” might leap upon and slay him; when wild beasts roamed the forest and the jungles, and there were savage men, and countries yet unexplored. Now, in all the Western Hemisphere dwells no man who may not find a school house within walking distance of his home, or at least within flying distance. The wildest beast that roams our waste places lairs in the frozen north or the frozen south within a government reserve, where the curious may view him and feed him bread crusts from the hand with perfect impunity. But beyond thirty! And I have gone there, and come back; and now you may go there, for no longer is it high treason, punishable by disgrace or death, to cross 30° or 175°. My name is Jefferson Turck. I am a lieutenant in the navy—in the great Pan-American navy, the only navy which now exists in all the world. I was born in Arizona, in the United States of North America, in the year of our Lord 2116. Therefore, I am twenty-one years old. In early boyhood I tired of the teeming cities and overcrowded rural districts of Arizona. Every generation of Turcks for over two centuries has been represented in the navy. The navy called to me, as did the free, wide, unpeopled spaces of the mighty oceans. And so I joined the navy, coming up from the ranks, as we all must, learning our craft as we advance. My promotion was rapid, for my family seems to inherit naval lore. We are born officers, and I reserve to myself no special credit for an early advancement in the service. At twenty I found myself a lieutenant in command of the aero-submarine Coldwater, of the SS-96 class. The Coldwater was one of the first of the air and underwater craft which have been so greatly improved since its launching, and was possessed of innumerable weaknesses which, fortunately, have been eliminated in more recent vessels of similar type. Even when I took command, she was fit only for the junk pile; but the world-old parsimony of government retained her in active service, and sent two hundred men to sea in her, with myself, a mere boy, in command of her, to patrol thirty from Iceland to the Azores.
