But in our particular case there was another perturbing factor. The sun, in its annual march north through the heavens, was increasing its declination. On the 19th parallel of north latitude in the middle of May the sun is nearly overhead. The angle of arc was between eighty-eight and eighty-nine degrees. Had it been ninety degrees it would have been straight overhead. It was on another day that we learned a few things about taking the altitude of the almost perpendicular sun. Roscoe started in drawing the sun down to the eastern horizon, and he stayed by that point of the compass despite the fact that the sun would pass the meridian to the south. I, on the other hand, started in to draw the sun down to south-east and strayed away to the south-west. You see, we were teaching ourselves. As a result, at twenty-five minutes past twelve by the ship’s time, I called twelve o’clock by the sun. Now this signified that we had changed our location on the face of the world by twenty-five minutes, which was equal to something like six degrees of longitude, or three hundred and fifty miles. This showed the Snark had travelled fifteen knots per hour for twenty-four consecutive hours—and we had never noticed it! It was absurd and grotesque. But Roscoe, still looking east, averred that it was not yet twelve o’clock. He was bent on giving us a twenty-knot clip. Then we began to train our sextants rather wildly all around the horizon, and wherever we looked, there was the sun, puzzlingly close to the sky-line, sometimes above it and sometimes below it. In one direction the sun was proclaiming morning, in another direction it was proclaiming afternoon. The sun was all right—we knew that; therefore we were all wrong. And the rest of the afternoon we spent in the cockpit reading up the matter in the books and finding out what was wrong. We missed the observation that day, but we didn’t the next. We had learned. We climbed the crater-walls, put the horses over impossible places, rolled stones, and shot wild goats. I did not get any goats. I was too busy rolling stones. One spot in particular I remember, where we started a stone the size of a horse. It began the descent easy enough, rolling over, wobbling, and threatening to stop; but in a few minutes it was soaring through the air two hundred feet at a jump. It grew rapidly smaller until it struck a slight slope of volcanic sand, over which it darted like a startled jackrabbit, kicking up behind it a tiny trail of yellow dust. Stone and dust diminished in size, until some of the party said the stone had stopped. That was because they could not see it any longer. It had vanished into the distance beyond their ken. Others saw it rolling farther on—I know I did; and it is my firm conviction that that stone is still rolling.!

“Is he all right?” meaning the parrot. She proposed to the girl to go to see her sister in Trouville.

CHAPTER II By this time the Snark was at sea on her way to Fiji. I remembered the French sailor, and for the first time became seriously alarmed. Four other similar sores had appeared—or ulcers, rather, and the pain of them kept me awake at night. All my plans were made to lay up the Snark in Fiji and get away on the first steamer to Australia and professional M.D.’s. In the meantime, in my amateur M.D. way, I did my best. I read through all the medical works on board. Not a line nor a word could I find descriptive of my affliction. I brought common horse-sense to bear on the problem. Here were malignant and excessively active ulcers that were eating me up. There was an organic and corroding poison at work. Two things I concluded must be done. First, some agent must be found to destroy the poison. Secondly, the ulcers could not possibly heal from the outside in; they must heal from the inside out. I decided to fight the poison with corrosive sublimate. The very name of it struck me as vicious. Talk of fighting fire with fire! I was being consumed by a corrosive poison, and it appealed to my fancy to fight it with another corrosive poison. After several days I alternated dressings of corrosive sublimate with dressings of peroxide of hydrogen. And behold, by the time we reached Fiji four of the five ulcers were healed, while the remaining one was no bigger than a pea. “Say good-bye to him, now!” she commanded.
