CHAPTER XXXIX.
About seven o'clock one blistering hot morning--for it was now dead summer time--Higbie and I took the boat and started on a voyage of discovery to the two islands. We had often longed to do this, but had been deterred by the fear of storms; for they were frequent, and severe enough to capsize an ordinary row-boat like ours without great difficulty--and once capsized, death would ensue in spite of the bravest swimming, for that venomous water would eat a man's eyes out like fire, and burn him out inside, too, if he shipped a sea. It was called twelve miles, straight out to the islands--a long pull and a warm one--but the morning was so quiet and sunny, and the lake so smooth and glassy and dead, that we could not resist the temptation. So we filled two large tin canteens with water (since we were not acquainted with the locality of the spring said to exist on the large island), and started. Higbie's brawny muscles gave the boat good speed, but by the time we reached our destination we judged that we had pulled nearer fifteen miles than twelve.
We landed on the big island and went ashore. We tried the water in the canteens, now, and found that the sun had spoiled it; it was so brackish that we could not drink it; so we poured it out and began a search for the spring--for thirst augments fast as soon as it is apparent that one has no means at hand of quenching it. The island was a long, moderately high hill of ashes--nothing but gray ashes and pumice-stone, in which we sunk to our knees at every step--and all around the top was a forbidding wall of scorched and blasted rocks. When we reached the top and got within the wall, we found simply a shallow, far-reaching basin, carpeted with ashes, and here and there a patch of fine sand. In places, picturesque jets of steam shot up out of crevices, giving evidence that although this ancient crater had gone out of active business, there was still some fire left in its furnaces. Close to one of these jets of steam stood the only tree on the island--a small pine of most graceful shape and most faultless symmetry; its color was a brilliant green, for the steam drifted unceasingly through its branches and kept them always moist. It contrasted strangely enough, did this vigorous and beautiful outcast, with its dead and dismal surroundings. It was like a cheerful spirit in a mourning household.
We hunted for the spring everywhere, traversing the full length of the island (two or three miles), and crossing it twice--climbing ash-hills patiently, and then sliding down the other side in a sitting posture, plowing up smothering volumes of gray dust. But we found nothing but solitude, ashes and a heart-breaking silence. Finally we noticed that the wind had risen, and we forgot our thirst in a solicitude of greater importance; for, the lake being quiet, we had not taken pains about securing the boat. We hurried back to a point overlooking our landing place, and then--but mere words cannot describe our dismay--the boat was gone! The chances were that there was not another boat on the entire lake. The situation was not comfortable--in truth, to speak plainly, it was frightful. We were prisoners on a desolate island, in aggravating proximity to friends who were for the present helpless to aid us; and what was still more uncomfortable was the reflection that we had neither food nor water. But presently we sighted the boat. It was drifting along, leisurely, about fifty yards from shore, tossing in a foamy sea. It drifted, and continued to drift, but at the same safe distance from land, and we walked along abreast it and waited for fortune to favor us. At the end of an hour it approached a jutting cape, and Higbie ran ahead and posted himself on the utmost verge and prepared for the assault. If we failed there, there was no hope for us. It was driving gradually shoreward all the time, now; but whether it was driving fast enough to make the connection or not was the momentous question. When it got within thirty steps of Higbie I was so excited that I fancied I could hear my own heart beat. When, a little later, it dragged slowly along and seemed about to go by, only one little yard out of reach, it seemed as if my heart stood still; and when it was exactly abreast him and began to widen away, and he still standing like a watching statue, I knew my heart did stop. But when he gave a great spring, the next instant, and lit fairly in the stern, I discharged a war-whoop that woke the solitudes!
