Mollie Craft had had a long conversation with the ship's surgeon, Dr. Town, the day previous, and had shown him the mysterious letter, and asked his assistance; the doctor had readily consented to aid her by all means in his power. Captain Gordon gave Mollie until 20 dial to return to the vessel before shaping his course for San Francisco. CHAPTER XIX At 8 dial that bright day of January 5, 2001, an expectant and anxious party left the deck of the San Francisco, and landed at the mole of Noniva. The Doctor had two men from the ship to carry the stretcher--he was a thoughtful man, and always had a stretcher along for emergencies--and the tools and such things as he believed might be needed. In the town, saddle mules were obtained, and the party of five quietly left the vicinity, as if for a day's camping in the hills. The journey was through a broken and thickly-wooded country, and the traveling slow and tedious. It was long past the meridian when the party reached and passed up the dry bed of the Ninta River, and nearly 15 dial when "The Finger of God," which all recognized from the description furnished by the natives of Noniva, was reached. The gray cliffs on either bank of the river were steep and rugged. Huge festoons of tropical growth covered them from top to bottom, and stunted pines stood nodding their crested heads among the rocky crevices. Already the shadow of the rock was creeping up the eastern bank, and by its position the pathway ledge was easily found. Leaving the two seamen at the base of the rock, Dr. Town, with the tools which he had brought, and followed by the two girls, carefully made his way up the narrow, overhanging ledge, and stood near the point of the dark shadow on the face of the rock. With watch in hand, which he had set to the meridian of Guadalupe, he awaited the time of 16 dial, or 4 P. M., as recorded by the author of the letter of instructions. The minutes passed slowly--too slowly for the two girls, who stood by his side. Their feelings were wrought to a fever heat; their hearts beat a tattoo within their bosoms, and a fear of some dreadful revelation possessed their souls. The shadow crept on; the sun was going down to its bed in the ocean, which spread out in every direction. On moved the shadow; it had reached a dense cluster of mountain-ivy, which completely hid the rock from view: the hour was 15:55 dial. Seizing a large knife from his bundle of tools, the doctor sprang quickly to the spot, and with dispatch, cleared away the evergreen, exposing the solid rock of the cliffs. With his eyes upon his watch, he noted the passing moments. "Sixteen dial!" he cried, and placed the point of his knife at the end of the shadow of the "Finger of God."
