It was instinct, and not reason or experience, which told Peter there was menace and peril in these two tiny spots blazing in the gloom.  He did not know that his own eyes, popping half out of his head, were equally terrifying in that pit of silence, nor that from him emanated a still more terrifying thing—­the scent of dog.  He trembled on his wobbly legs as the green eyes stared at him, and his back seemed to break in the middle, so that he sank helplessly down upon the soft spruce needles, waiting for his doom.  In another flash the twin balls of green fire were gone.  In a moment they appeared again, a little farther away.  Then a second time they were gone, and a third time they flashed back at him—­so distant they appeared like needle-points in the darkness.  Something stupendous rose up in Peter.  It was the soul of his Airedale father, telling him the other thing was running away!  And in the joy of triumph Peter let out a yelp.  In that night-infested place, alive with hiding things, the yelp set loose weird rustlings in the tangled treetops, strange murmurings of chortling voices, and the nasty snapping of beaks that held in them the power to rend Peter’s skinny body into a hundred bits.  From deeper in the thicket came the sudden crash of a heavy body, and with it the chuckling notes of a porcupine, and a Hoo-Hoo-Hoo-Ee of startled inquiry that at first Peter took for a human voice.  And again he lay shivering close to the foot-deep carpet of needles under him, while his heart thumped against his ribs, and his whiskers stood out in mortal fear.  There followed a weird and appalling silence, and in that stillness Peter quested vainly for the sunlight he had lost.  And then, indistinctly, but bringing with it a new thrill, he heard another sound.  It was a soft and distant rippling of running water.  He knew that sound.  It was friendly.  He had played among the rocks and pebbles and sand where it was made.  His courage came back, and he rose up on his legs, and made his way toward it.  Something inside him told him to go quietly, but his feet were big and clumsy, and half a dozen times in the next two minutes he stumbled on his nose.  At last he came to the stream, scarcely wider than a man might have reached across, rippling and plashing its way through the naked roots of trees.  And ahead of him Peter saw light.  He quickened his pace, until at the last he was running when he came out into the edge of the meadowy plain, with its sweetness of flowers and green grass and song of birds, and its glory of blue sky and sun.

If he had ever been afraid, Peter forgot it now.  The choking went out of his throat, his heart fell back in its place, and the fierce conviction that he had vanquished everything in the world possessed him.  He peered back into the dark cavern of evergreen out of which the streamlet gurgled, and then trotted straight away from it, growling back his defiance as he ran.  At a safe distance he stopped, and
