And then, when at last we reached the summit of that monster mountain, which summit was like the bottom of an inverted cone situated in the centre of an awful cosmic pit, we found that we were at neither top nor bottom. Far above us was the heaven-towering horizon, and far beneath us, where the top of the mountain should have been, was a deeper deep, the great crater, the House of the Sun. Twenty-three miles around stretched the dizzy walls of the crater. We stood on the edge of the nearly vertical western wall, and the floor of the crater lay nearly half a mile beneath. This floor, broken by lava-flows and cinder-cones, was as red and fresh and uneroded as if it were but yesterday that the fires went out. The cinder-cones, the smallest over four hundred feet in height and the largest over nine hundred, seemed no more than puny little sand-hills, so mighty was the magnitude of the setting. Two gaps, thousands of feet deep, broke the rim of the crater, and through these Ukiukiu vainly strove to drive his fleecy herds of trade-wind clouds. As fast as they advanced through the gaps, the heat of the crater dissipated them into thin air, and though they advanced always, they got nowhere. So the Snark comes back on her course. The breath increases to a tiny puff. The Snark feels the weight of it and actually heels over a trifle. There is flying scud overhead, and I notice the stars being blotted out. Walls of darkness close in upon me, so that, when the last star is gone, the darkness is so near that it seems I can reach out and touch it on every side. When I lean toward it, I can feel it loom against my face. Puff follows puff, and I am glad the mizzen is furled. Phew! that was a stiff one! The Snark goes over and down until her lee-rail is buried and the whole Pacific Ocean is pouring in. Four or five of these gusts make me wish that the jib and flying-jib were in. The sea is picking up, the gusts are growing stronger and more frequent, and there is a splatter of wet in the air. There is no use in attempting to gaze to windward. The wall of blackness is within arm’s length. Yet I cannot help attempting to see and gauge the blows that are being struck at the Snark. There is something ominous and menacing up there to windward, and I have a feeling that if I look long enough and strong enough, I shall divine it. Futile feeling. Between two gusts I leave the wheel and run forward to the cabin companionway, where I light matches and consult the barometer. “29-90” it reads. That sensitive instrument refuses to take notice of the disturbance which is humming with a deep, throaty voice in the rigging. I get back to the wheel just in time to meet another gust, the strongest yet. Well, anyway, the wind is abeam and the Snark is on her course, eating up easting. That at least is well.!

“Will you have some iced tea?” asked the Madonna; and then her side of the table sank down gently and I said yes to her at an angle of forty-five degrees. And now, in simple language. I shall describe how I taught myself navigation. One whole afternoon I sat in the cockpit, steering with one hand and studying logarithms with the other. Two afternoons, two hours each, I studied the general theory of navigation and the particular process of taking a meridian altitude. Then I took the sextant, worked out the index error, and shot the sun. The figuring from the data of this observation was child’s play. In the “Epitome” and the “Nautical Almanac” were scores of cunning tables, all worked out by mathematicians and astronomers. It was like using interest tables and lightning-calculator tables such as you all know. The mystery was mystery no longer. I put my finger on the chart and announced that that was where we were. I was right too, or at least I was as right as Roscoe, who selected a spot a quarter of a mile away from mine. Even he was willing to split the distance with me. I had exploded the mystery, and yet, such was the miracle of it, I was conscious of new power in me, and I felt the thrill and tickle of pride. And when Martin asked me, in the same humble and respectful way I had previously asked Roscoe, as to where we were, it was with exaltation and spiritual chest-throwing that I answered in the cipher-code of the higher priesthood and heard Martin’s self-abasing and worshipful “Oh.” As for Charmian, I felt that in a new way I had proved my right to her; and I was aware of another feeling, namely, that she was a most fortunate woman to have a man like me.

He had died. The letter told nothing more. There is a familiar and strange illusion experienced by all who climb isolated mountains. The higher one climbs, the more of the earth’s surface becomes visible, and the effect of this is that the horizon seems up-hill from the observer. This illusion is especially notable on Haleakala, for the old volcano rises directly from the sea without buttresses or connecting ranges. In consequence, as fast as we climbed up the grim slope of Haleakala, still faster did Haleakala, ourselves, and all about us, sink down into the centre of what appeared a profound abyss. Everywhere, far above us, towered the horizon. The ocean sloped down from the horizon to us. The higher we climbed, the deeper did we seem to sink down, the farther above us shone the horizon, and the steeper pitched the grade up to that horizontal line where sky and ocean met. It was weird and unreal, and vagrant thoughts of Simm’s Hole and of the volcano through which Jules Verne journeyed to the centre of the earth flitted through one’s mind. 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.
