is soul—that of a true explorer—revolted, not at the thought of death, but that his and Alden's courageously won discovery of a majestic mountain range towering high over a polar region marked "unexplored" on the maps would now never be made public.

Leaning forward against the merciless icy blast he painfully picked his way over a treacherous ice ridge, to be faintly encouraged by the fact that the towerlike hummock of ice marking the position of the plane now lay but a few hundred yards ahead.

Bitterly he cursed that demon of ill-fortune who had sent the blinding snow storm which had forced down the plane ten long days ago at the very beginning of its triumphant return flight to the base at Cape Richards. Since that hour the storm gods had emptied the vials of their wrath upon the luckless explorers. Day after day, cyclonic winds made all thought of a take-off suicidal in the extreme. Three days ago the last of their food had given out, and, he mused, starvation is an ill companion for despair.

Slip, slide and fall! On he fought until the final barrier was reached and he stood staring hopelessly down into a small natural amphitheater which sheltered the great monoplane. The ship was still there, its engine snugged in a canvas shroud and with the soft, dry snow banked up high in the lee of its silver gray fuselage. Numbly, like a man in the grip of a painful coma, Nelson shielded his face with a furry hand to scan the surrounding terrain. "Hell!" The door block of the igloo they had built was still snowed up; Alden was not there!

"He's not back," he muttered, while his body swayed beneath the gale which smote him with fierce, unseen fists. "Poor devil, I hope he hasn't lost the way."

All the bitterness of undeserved defeat stung his soul as he started down the incline into the hollow.
