By this time they had reached the rough and rocky piece of ground, and had to pick their way carefully without being able to talk much. Peter was on ahead, and suddenly they heard him shouting to them in a voice which seemed full of fear; and when they looked they saw him gesticulating wildly, and pointing up into the mountain’s side above them, where Squib saw an odd-looking little cloud of dust coming tumbling down.

“What is it?” he asked curiously, pausing to stare; but when he glanced into Herr Adler’s face he saw that it was very grave, although there was no fear in the steady blue eyes.

“It is a little avalanche, my boy,” said Herr Adler quickly. “Run on to Peter as fast as you can. You see that great wall of rock under which the path lies, run on there quickly, and stand up under its shelter. I will follow you as fast as I can; but run you on, and take Peter with you. That is what he is motioning us to do.”

“May I not stay with you?” asked Squib. “I should like to keep together.”

“I would rather you ran on first, my child. I shall not be far behind.”

Something in the look and tone made Squib obey, although he would rather have kept at Herr Adler’s side. As soon as he got up to Peter, the elder boy grasped him by the hand and hurried him along at a great pace, and all the while he kept gasping out excited, disjointed fragments of talk, by which Squib made out that they were just in the very track of the dangerous falls of stone which were dislodged by the little avalanches up in the mountain slopes, and that their only chance of safety was to shelter themselves under the protecting wall of rock. Even there they might chance to meet with injury, but in the open they could hardly hope to escape.

Squib and Peter quickly reached the shelter, and turned round in an agony of apprehension and anxiety to see where Herr Adler was. He was not far behind, and was making his way rapidly towards them. Squib was glad to note that Czar remained beside him, as though with some instinct of protection, although, poor fellow, it was little aid he could give if the avalanche came upon them.

“Oh, come quick—come quick!” cried Squib, darting forward to pull his friend in under the friendly shelter of the great rocky wall; and when they were all there together, Herr Adler found a place where a deep crevice in the wall of rock enabled both the children to stand in almost perfect safety, whilst he remained close to them; and they all held their breath to listen to the strange rushing and grinding sounds above them, which grew louder and fiercer every moment.

“O sir, do come inside, and let me stand where you are!” pleaded Squib earnestly; but Herr Adler smiled, and put his hand gently on the child’s head.

“I would rather we stayed as we are, my child,” he said. “Your mother trusted you to me, and I must restore you to her safe and sound; but I think we shall all of us be preserved from injury.”
