“Corrosive sublimate,” said Mr. Drew. We had a lunch of jerked beef and hard poi in a stone corral, used of old time for the night-impounding of cattle being driven across the island. Then we skirted the rim for half a mile and began the descent into the crater. Twenty-five hundred feet beneath lay the floor, and down a steep slope of loose volcanic cinders we dropped, the sure-footed horses slipping and sliding, but always keeping their feet. The black surface of the cinders, when broken by the horses’ hoofs, turned to a yellow ochre dust, virulent in appearance and acid of taste, that arose in clouds. There was a gallop across a level stretch to the mouth of a convenient blow-hole, and then the descent continued in clouds of volcanic dust, winding in and out among cinder-cones, brick-red, old rose, and purplish black of colour. Above us, higher and higher, towered the crater-walls, while we journeyed on across innumerable lava-flows, turning and twisting a devious way among the adamantine billows of a petrified sea. Saw-toothed waves of lava vexed the surface of this weird ocean, while on either hand arose jagged crests and spiracles of fantastic shape. Our way led on past a bottomless pit and along and over the main stream of the latest lava-flow for seven miles.!

Aha, thought I, now at last is he going to pester me with his literary efforts. My soul was in revolt. I had not come all the way to the South Seas to be a literary bureau. But there are compensations. On Wednesday evening, June 10, I brought up my noon position by dead reckoning to eight P.M. Then I projected the Snark’s course and saw that she would strike Futuna, one of the easternmost of the New Hebrides, a volcanic cone two thousand feet high that rose out of the deep ocean. I altered the course so that the Snark would pass ten miles to the northward. Then I spoke to Wada, the cook, who had the wheel every morning from four to six.

Our last day in the crater, Ukiukiu gave us a taste of his strength. He smashed Naulu back all along the line, filled the House of the Sun to overflowing with clouds, and drowned us out. Our rain-gauge was a pint cup under a tiny hole in the tent. That last night of storm and rain filled the cup, and there was no way of measuring the water that spilled over into the blankets. With the rain-gauge out of business there was no longer any reason for remaining; so we broke camp in the wet-gray of dawn, and plunged eastward across the lava to the Kaupo Gap. East Maui is nothing more or less than the vast lava stream that flowed long ago through the Kaupo Gap; and down this stream we picked our way from an altitude of six thousand five hundred feet to the sea. This was a day’s work in itself for the horses; but never were there such horses. Safe in the bad places, never rushing, never losing their heads, as soon as they found a trail wide and smooth enough to run on, they ran. There was no stopping them until the trail became bad again, and then they stopped of themselves. Continuously, for days, they had performed the hardest kind of work, and fed most of the time on grass foraged by themselves at night while we slept, and yet that day they covered twenty-eight leg-breaking miles and galloped into Hana like a bunch of colts. Also, there were several of them, reared in the dry region on the leeward side of Haleakala, that had never worn shoes in all their lives. Day after day, and all day long, unshod, they had travelled over the sharp lava, with the extra weight of a man on their backs, and their hoofs were in better condition than those of the shod horses. The handcuffs were promptly put upon the pump, and once a day the water was portioned out. Each of us received a quart for personal use, and eight quarts were given to the cook. Enters now the psychology of the situation. No sooner had the discovery of the water shortage been made than I, for one, was afflicted with a burning thirst. It seemed to me that I had never been so thirsty in my life. My little quart of water I could easily have drunk in one draught, and to refrain from doing so required a severe exertion of will. Nor was I alone in this. All of us talked water, thought water, and dreamed water when we slept. We examined the charts for possible islands to which to run in extremity, but there were no such islands. The Marquesas were the nearest, and they were the other side of the Line, and of the doldrums, too, which made it even worse. We were in 3° north latitude, while the Marquesas were 9° south latitude—a difference of over a thousand miles. Furthermore, the Marquesas lay some fourteen degrees to the west of our longitude. A pretty pickle for a handful of creatures sweltering on the ocean in the heat of tropic calms. The camera cannot do justice to the House of the Sun. The sublimated chemistry of photography may not lie, but it certainly does not tell all the truth. The Koolau Gap may be faithfully reproduced, just as it impinged on the retina of the camera, yet in the resulting picture the gigantic scale of things would be missing. Those walls that seem several hundred feet in height are almost as many thousand; that entering wedge of cloud is a mile and a half wide in the gap itself, while beyond the gap it is a veritable ocean; and that foreground of cinder-cone and volcanic ash, mushy and colourless in appearance, is in truth gorgeous-hued in brick-red, terra-cotta rose, yellow ochre, and purplish black. Also, words are a vain thing and drive to despair. To say that a crater-wall is two thousand feet high is to say just precisely that it is two thousand feet high; but there is a vast deal more to that crater-wall than a mere statistic. The sun is ninety-three millions of miles distant, but to mortal conception the adjoining county is farther away. This frailty of the human brain is hard on the sun. It is likewise hard on the House of the Sun. Haleakala has a message of beauty and wonder for the human soul that cannot be delivered by proxy. Kolikoli is six hours from Kahului; Kahului is a night’s run from Honolulu; Honolulu is six days from San Francisco; and there you are.
