The lake was fully half a mile long, and at the foot of the precipice but a few yards wide. Now, I had prodigious strength of arm, and I took advantage of those water cattle by selecting a lot of good-sized stones, which I threw with all my might; and so great was the space traveled by them before they struck, the crocodiles could not swim the space in several minutes. As the stones began to strike the water they were all excitement, and at once proceeded to learn the cause of the disturbance, and away they went. When they had all reached the spot, I sprang head first into the water, and rising easily to the surface swam to shore before they had fairly got started back to investigate the new commotion. While standing on the summit of the rock I had decided which of several paths I should take, the one I had selected being through a grassy bit of country. Over this I went upwards of a mile, when I found my further progress impeded by a swarm of deadly vipers, which so filled the way I could scarcely see the ground. They were having a very quiet time, but on becoming aware of my presence they set up such a rattling I thought for a moment there was a shower of pebbles falling on the rocks. Now, being possessed of a very strong pair of boots, which came high on my legs, I could readily have stamped them all to death, but I dare not harm them, and I knew that to attempt to pass them and leave them unhurt was simple suicide. I therefore hit upon the following plan to evade them and continue my way: As I was passing through the water on my dive I had observed a beautiful colored shell on the bottom of the lake, and had brought it with me. I now looked it over. As the snakes had not yet determined to attack me because I had not disturbed them, I stepped to a large boulder of sandstone near by, and by dint of using it as a grinder I succeeded in wearing away the end of the shell. Then, by the aid of a sharp stone, I bored eight holes in it at proper intervals. When I had done, I put the instrument to my lips and began to play on it, for, as I have stated before, I believe, I am an accomplished musician. I executed a low, plaintive air at first, which appeared to please my audience and they uncoiled themselves and assumed a less warlike attitude. Then I shortened the time and had them dancing for joy. When I had them thus entranced I cautiously made my way through their numbers and changed to a very slow and heavy measure, and in a very short time had put them all soundly to sleep, in which condition I left them and went onward. [Illustration] I was now approaching another mountain and was suddenly stopped by an abrupt end to the path. There was no mistaking the fact, the path turned neither to the right nor to the left, but that the way to the secret chamber lay up a perpendicular wall a hundred feet high and as smooth as glass.
