We gave up the jungle and sought the stream with the idea of evading the sand-flies. Vain hope! To go in swimming one must take off his clothes. The sand-flies are aware of the fact, and they lurk by the river bank in countless myriads. In the native they are called the nau-nau, which is pronounced “now-now.” They are certainly well named, for they are the insistent present. There is no past nor future when they fasten upon one’s epidermis, and I am willing to wager that Omer Khayyám could never have written the Rubáiyat in the valley of Typee—it would have been psychologically impossible. I made the strategic mistake of undressing on the edge of a steep bank where I could dive in but could not climb out. When I was ready to dress, I had a hundred yards’ walk on the bank before I could reach my clothes. At the first step, fully ten thousand nau-naus landed upon me. At the second step I was walking in a cloud. By the third step the sun was dimmed in the sky. After that I don’t know what happened. When I arrived at my clothes, I was a maniac. And here enters my grand tactical error. There is only one rule of conduct in dealing with nau-naus. Never swat them. Whatever you do, don’t swat them. They are so vicious that in the instant of annihilation they eject their last atom of poison into your carcass. You must pluck them delicately, between thumb and forefinger, and persuade them gently to remove their proboscides from your quivering flesh. It is like pulling teeth. But the difficulty was that the teeth sprouted faster than I could pull them, so I swatted, and, so doing, filled myself full with their poison. This was a week ago. At the present moment I resemble a sadly neglected smallpox convalescent. Not so was the leper and his greatly misunderstood and feared disease treated during the middle ages in Europe. At that time the leper was considered legally and politically dead. He was placed in a funeral procession and led to the church, where the burial service was read over him by the officiating clergyman. Then a spadeful of earth was dropped upon his chest and he was dead-living dead. While this rigorous treatment was largely unnecessary, nevertheless, one thing was learned by it. Leprosy was unknown in Europe until it was introduced by the returning Crusaders, whereupon it spread slowly until it had seized upon large numbers of the people. Obviously, it was a disease that could be contracted by contact. It was a contagion, and it was equally obvious that it could be eradicated by segregation. Terrible and monstrous as was the treatment of the leper in those days, the great lesson of segregation was learned. By its means leprosy was stamped out.!

Still the circle narrowed, till canoes were almost touching. There was a pause. A long canoe shot out from shore, following the line of the circle. It went as fast as paddles could drive. In the stern a man threw overboard the long, continuous screen of cocoanut leaves. The canoes were no longer needed, and overboard went the men to reinforce the palisade with their legs. For the screen was only a screen, and not a net, and the fish could dash through it if they tried. Hence the need for legs that ever agitated the screen, and for hands that splashed and throats that yelled. Pandemonium reigned as the trap tightened. It took another thirty minutes to reach Trouville. The little caravan dismounted in order to pass Les Ecores, a cliff that overhangs the bay, and a few minutes later, at the end of the dock, they entered the yard of the Golden Lamb, an inn kept by Mother David.

She wept so sorely that her mistress said: “Why don’t you have him stuffed?” Nor on the question of fever were the “Sailing Directions” any more encouraging, for in them I read: But alas and alack and lucky for me, I read on. I discovered that the compass, that trusty, everlasting friend of the mariner, was not given to pointing north. It varied. Sometimes it pointed east of north, sometimes west of north, and on occasion it even turned tail on north and pointed south. The variation at the particular spot on the globe occupied by the Snark was 9° 40′ easterly. Well, that had to be taken into account before I gave the steering course to the man at the wheel. I read:
