Off ran the boys, and in a short time the basket was securely hung between Storm and Grumble. Fritz and Jack sprang into their saddles, and Ernest very gingerly deposited himself in the "cradle," as Franz called it; they set forth at a most sober pace, the animals, who were perfectly docile, appearing only a little surprised at the new arrangement. "Oh, it is so pleasant, mother, it is a delightful motion," cried Ernest, as they passed us; "it swings and rocks really soothingly. Quicker, Fritz! go quicker!" and the trot pleasing him equally well, the pace gradually quickened, till the animals were going along at a rate which shook and jolted the basket about most fearfully. Ernest called and screamed in vain for a halt. His brothers thought it capital fun to "shake up" the "professor," and made the circuit of the level ground near Rockburg, finally pulling up in front of us, like performers stopping to receive the applause of spectators. It was impossible to help laughing, the scene was so ridiculous, but Ernest was very angry with his brothers, his reproaches provoked high words in reply, and a quarrel was imminent, but I interfered, and showed them how easily a joke, carried too far, would lead to disputes and bad feeling, urging them to avoid on all occasions any breach of the good-fellowship and brotherly love which was the mainstay of our strength and happiness. Good humor was soon restored, Ernest himself helped to unharness the beasts, and got some handfuls of salt and barley to reward their exertions, saying that they must have some more palanquin-practice another day. I was seated with my wife and Fritz beneath the shade of the veranda, engaged in wicker-work, and chatting pleasantly, when suddenly Fritz got up, advanced a step or two, gazing fixedly along the avenue which led from Jackal River, then he exclaimed: "I see something so strange in the distance, father! What in the world can it be? first it seems to be drawn in coils on the ground like a cable, then uprises as it were a little mast, then that sinks, and the coils move along again. It is coming toward the bridge." My wife took alarm at this description, and calling the other boys, retreated into the cave, where I desired them to close up the entrances, and keep watch with firearms at the upper windows. These were openings we had made in the rock at some elevation, reached within by steps, and a kind of gallery which passed along the front of the rooms. Fritz remained by me while I examined the object through my spyglass. "It is, as I feared, an enormous serpent!" cried I; "it advances directly this way, and we shall be placed in the greatest possible danger, for it will cross the bridge to a certainty." "May we not attack it, father?" exclaimed the brave boy.
