"By glancing at this map of Hili-liland, you will observe that the sea-course to 'Crater Mountains' was almost direct, it lying in a straight line out of Hili-li Bay and across the open sea for thirty miles. They were to enter 'Volcano Bay,' which pursued a tortuous course amid the mountains, until they should reach a certain pass between two of the highest mountains in the whole range. In the centre of one of these mountains was a peak some eight miles high, named by the founders of Hili-li 'Mount Olympus.' It was possible to sail (or to push their boat) to within seven miles of a point where the lavabed was still red hot--about thirteen miles from the edge of the central, white-hot, boiling lava. This, however, they did not do; first, because the pass mentioned, which was the best course up into the mountains, began about three or four miles short of the inner extremity of Volcano Bay; and second, because within a mile or two of that extremity the water of the bay sometimes actually boiled, and the heat would there be quite unendurable." Here Bainbridge paused for a moment, and then continued, "Well, my attentive friend, 'the witching hour' approaches. We lost too much time in discussion this evening--What! only ten o'clock?" he said, looking at his watch. "Well, I am at a good resting-place in the story, anyway, as you will to-morrow evening admit. Why, if I started you up into those mountains to-night, we should get no sleep before daylight. No, no: 'sufficient unto the day is the evil thereof; more I would'--how does it go? Well, it means that the evils of two days should not be crowded into one day. The attempted quotation--as generally happens when I attempt quotation from the Bible--is a double failure: not a success simply in accuracy of repetition; and, at best, not appropriate. For I have more, and a great deal more. But"--rising from his chair--"I must depart. So adieu until the morrow--and good-night to you." He had not been gone five minutes, and I was just complimenting Arthur on his silence and otherwise commendable behavior, when Doctor Castleton bounced into the room. He knew in a general way the drift of Peters' story, up to the developments of the evening before. His curiosity to hear what Doctor Bainbridge had so patiently and laboriously gleaned from Peters did not seem intense, or it was wonderfully well suppressed. Still, he liked briefly to learn from me the outlines of the story, and had not failed to meet me at some period of each day, and to hint at a desire for information. Therefore, I knew with what object he had this evening come to see me, and I ran rapidly over the facts developed the preceding evening, and then over those of that evening.
