It was near the Pali that I saw what I had never seen or heard of before—a waterfall reversed, going up instead of down. It suggested Stockton's story of negative gravity. A small brook comes down off the mountain and attempts to make the leap down a high precipice; but the winds catch it and carry it straight up in the air like smoke. It is translated; it becomes a mere wraith hovering above the beetling crag. Night and day this goes on, the wind snatching from the mountains in this summary way the water it has brought them.

On the walk with the Governor we made the acquaintance of some of the land shells for which these islands are famous—pretty, pearl-like little whorls living on the largest trees, and about the size of a chipping sparrow's egg, with pointed ends, variously colored. There are more than two hundred species on the different islands, I think, each valley having varieties peculiar to itself, showing what a factor isolation is in the evolution of new species. The Governor and his wife, and a young man who had specialized in conchology, plucked them from nearly every bush and tree; but my eye, being untrained in this kind of work, was very slow in finding them.

Coming down from these Hawaiian mountains is like coming out of a dripping tent of clouds into the clear, warm sunshine. The change is most delightful. Your clothing dries very quickly, and chilliness gives place to genial warmth. And the prospects that open before you, the glimpses down into these deep, yellow-green, crater-like valleys, checkered with neat little Chinese farms, the panorama of the city and the sea unrolling as you come down, and always Diamond Head standing guard there to the east—how the vision of it all lingers in the memory!

In climbing the heights, it was always a surprise to me to see the Pacific rise up as I rose, till it stood up like a great blue wall there against the horizon. A level plain unrolls in the same way as we mount above it, but it does not produce the same illusion of rising up like a wall or a mountain-range; the blue, facile water cheats the eye.

One of the novel pleasures in which most travelers indulge while in Honolulu is surf-riding at Waikiki, near Diamond Head. The sea, with a floor of lava and coral, is here shallow for a long distance out, and the surf comes in at intervals like a line of steeds cantering over a plain. We went out in our bathing-suits in a long, heavy dugout, with a lusty native oarsman in each end. When several hundred yards from shore, we saw, on looking seaward, the long, shining billows coming, whereupon our oarsmen headed the canoe toward shore, and plied their paddles with utmost vigor, uttering simultaneously a curious, excited cry. In a moment the breaker caught us and, in some way holding us on its crest, shot us toward the shore like an arrow. The sensation is novel and thrilling. The foam flies; the waters leap about you. You are coasting on the sea, and you shout with delight and pray for the sensation to continue. But it is quickly over. The hurrying breaker slips from under you, and leaves you in the trough, while it goes foaming on the shore. Then you turn about and row out from the shore again, and wait for another chance to be shot toward the land on the foaming crest of a great Pacific wave.

I suppose the trick is in the skill of the oarsmen in holding the boat on the pitch of the billow so that in its rush it takes you with it. The native boys do the feat standing on a plank. I was tempted to try this myself, but of course made a comical failure.

One of my pleasant surprises in Honolulu—one that gave the touch of nature which made me feel less a stranger there—was learning that the European skylark had been introduced and was thriving on the grassy slopes back of the city. The mina, a species of starling from India as large as our robin and rather showily dressed, with a loud, strident voice, I had seen and heard everywhere both in town and country, but he was a stranger and did not appeal to me. But the thought of the skylark brought Shelley and Wordsworth, and English downs and meadows, near to me at once, and I was eager to hear it. So early one morning we left the Pleasanton, our tarrying-place, and climbed the long, pastoral slope above the city, where cattle and horses were grazing, and listened for this minstrel from the motherland. We had not long to wait. Sure enough, not far from us there sprang from the turf Shelley's bird, and went climbing his invisible spiral toward the sky, pouring out those hurried, ecstatic notes, just as I had heard him above the South Downs of England. It was a moment of keen delight to me. The bird soared and hovered, drifting about, as it were, before the impetuous current of his song, with all the joy and abandon with which the poets have credited him. It was like a bit of English literature vocal in the air there above these alien scenes. Presently another went up, and then another, and still another, the singers behaving in every respect as they do by the Avon and the Tweed, and for a moment I seemed to be breathing the air that Wordsworth and Shelley breathed.

If our excursion had taken us only to the island of Oahu and its beautiful city, it would have been eminently worth while, but the last week in May we took what is called the inter-island trip, a six days' voyage among the various islands, when we visited the great extinct crater of Haleakala on Maui, and the active volcano Kilauea on Hawaii. It is a voyage over several rough channels in a small steamer, and my friends said, "If you have not yet paid tribute to Neptune, you will pay it now." But I did not. My companions were prostrated, but I see Neptune respects age, and my slumbers were undisturbed. A wireless message had gone to Mr. Aiken, on the island of Maui, to meet us with his automobile in the morning at the landing at Kahului. We were taken to the shore on a lighter, along with the horses and cargo, and there found our new friend awaiting us.

The great mountain of Haleakala rose up in a long line against the sky on the left, and the deeply eroded and canyoned mountains of the older, or west, end of the island on our right. Toward the latter our guide took us. It was a pleasant spin along the good roads, in the fresh morning air, near the beach, to Wailuku, the shire town of the island, two or three miles distant. Here we were most hospitably entertained in the home of Mr. Penhallow, the director of a large sugar plantation.

Here for the first time in my life I saw a gang of steam plows working, pulled by a stationary engine at each end of the field, and turning over the red, heavy volcanic soil. The work was mainly in the hands of Japanese, and was well done. We afterward saw Japanese by the score, both men and women, planting a large area of newly plowed land with sugar-cane.
