The revulsion of feeling was tremendous. Everyone sighed, and Mr Sudberry groaned, for at that moment the thought of poor Peter recurred to his mind. Yet there remained a strange feeling of kindliness in the breast of each towards that white horse. It was an undeniable proof of the existence of animal life in those wild regions, a fact which the deep solitude of all around had tempted them madly to doubt--unknown even to themselves. Besides, it suggested the idea of an owner to the horse; and by a natural and easy process of reasoning they concluded that the owner must be a human being, and that, when at home, he probably dwelt in a house. What more probable than that the house was even then within hail? Acting on the idea, Mr Sudberry shouted for two minutes with all his might, the only result of which was to render himself extremely hoarse. Then George tried it, and so did Fred, and Jacky awoke and began to whimper and to ask to be let down. He also kicked a little, but, being very tired, soon fell asleep again. "You _must_ let me carry him now!" said Fred. "I won't!" Fred tried force, but George was too strong for him, so they went on as before, Lucy leaning somewhat heavily on her father's arm. Presently they heard the sound of water. It filled them with mitigated joy and excitement, on the simple principle that _anything_ in the shape of variety was better than _nothing_. A clap of thunder would have raised in their depressed bosoms a gleam of hope. A flash of lightning would have been a positive blessing. Mr Sudberry at once suggested that it must be a stream, and that they could follow its course--wade down its bed, if necessary--till they should arrive at "something!" Foolish man! he had been long enough in the Highlands by that time to have known that to walk down the bed of a mountain-burn was about as possible as to walk down the shaft of a coal-mine. They came to the edge of its banks, however, and, looking over, tried to pierce its gloom. There was a pale gleam of white foam--a rumbling, rustling sound beneath, and a sensation of moisture in the atmosphere. "It rains!" said Mr Sudberry. "I rather think it's the spray of a fall!" observed George. Had Mr Sudberry known the depth of the tremendous gulf into which he was peering, and the steep cliff on the edge of which he stood, he would have sprung back in alarm. But he did not know--he did not entertain the faintest idea of the truth so he boldly, though cautiously, began to clamber down, assisting Lucy to descend. Man, (including woman), knows not what he can accomplish until he tries. Millions of glittering gold would not have induced any member of that party to descend such a place in the dark, had they known what it was-- yet they accomplished it in safety. Down, down they went! "Dear me, when shall we reach the foot? We must be near it now."
