The stalk was resumed, and slowly and carefully all crept along in single file, keeping to the depressions and rugged passages between the masses of ice.

It was a most laborious struggle, for the necessity of keeping out of sight forced all to go down in the most difficult places, and at times to lie flat and crawl and drag themselves over the higher portions which they had to cross.

But the excitement kept them well to their work, and in almost perfect silence they progressed till a sheltered nook was reached behind a ridge formed by the tilting of one of the ice-fields which had been forced ashore. Here they paused again to regain breath and steadiness of hand, for the exertion was great to reach this advantageous spot, just beyond which the walrus lay, the sea being close at hand. There was only a rough slope formed by the edge of the floe now lying at an angle of about thirty-five degrees for them to mount, rest their rifles on the edge, take aim each at the one he selected, and fire.

Johannes had directed the captain on the course taken, he seeming to know, as if by instinct, the way to bear and regain the straight line marked out when they had been turned aside by an obstacle; and now, after pointing out to the leader where to take his place, and then by signs only indicating the doctor’s, he turned to Steve, placed his lips to the boy’s ear, and said:

“Creep up slowly without a sound, slip your gun over, and take aim at one of the walrus that is side on to you. It is of no use to shoot anywhere; it must be straight behind the eye, and about six inches away, just where it looks all thick neck. They’re waiting; go on.”

Steve glanced to right and left, as Johannes crouched down beside Jakobsen, each man with his lance ready; and then the captain waved his hand, and they started together, crawling up slowly and silently till they were within a yard of the level ridge, where all paused as if animated by the same spirit, thrust the barrels of their pieces toward the top, and began to seek for the next places to plant their feet so as to peer over the edge together.

Steve’s heart beat with great throbs, and a curious nervous sensation came over him; but he was in position first, saw that the captain was ready the next moment, and then turned to the doctor, for it was of course necessary that all should fire together.

Steve was just in time to hear a sharp ejaculation, and see the doctor slip and roll down the ice slope, his rifle rattling after him with plenty of noise; and, knowing that if he were not quick there would be no shot, he raised himself up with rifle ready, thrust it over the ridge at the same time as the captain, and then stopped there staring.

“Fire! fire!” came in a whisper from Jakobsen.

“What at?” replied Steve, and the captain laughed good-humouredly.
