One moonlight night, running through the quiet forest, One Eye suddenly halted. His muzzle went up, his tail stiffened, and his nostrils dilated as he scented the air. One foot also he held up, after the manner of a dog. He was not satisfied, and he continued to smell the air, striving to understand the message borne upon it to him. One careless sniff had satisfied his mate, and she trotted on to reassure him. Though he followed her, he was still dubious, and he could not forbear an occasional halt in order more carefully to study the warning.

She crept out cautiously on the edge of a large open space in the midst of the trees. For some time she stood alone. Then One Eye, creeping and crawling, every sense on the alert, every hair radiating infinite suspicion, joined her. They stood side by side, watching and listening and smelling.
