They must, he reflected, be awaiting him anxiously, for he had been absent nearly five hours. In the gladness of his heart he put his hands to his mouth and made the glen re-echo to a loud halloo as a signal that he was coming. He paused and listened for an answer. None came save his own cry, which clattered up the dreary silent ravines, and was borne back to his ears in countless repetitions.

A vague, nameless dread came over him, and he hurried onwards frantically, dropping the precious food in his agitation.
