and caustically inquired whether neolithic man used babbit metal rivets to fasten on his jug handles.

Bram's brilliant work in the investigation of the origin of the negrito Asiatic races had been awarded one of the Nobel prizes, and Bram had declined it in an insulting letter because he disapproved of the year's prize award for literature.

He had been a storm center for years, embittered by long opposition, when he joined the Greystoke Expedition for the purpose of investigating the marine fauna of the antarctic continent.

And it was known that his presence had nearly brought the Greystoke Expedition to the point of civil war. Rumor said he had been deliberately abandoned. His enemies hoped he had. The facts seemed to be, however, that in an outburst of temper he had walked out of camp in a furious snowstorm and perished. For days his body had been sought in vain.

Jimmy Dodd had run foul of Bram some years before, when Bram had published a criticism of one of Dodd's addresses dealing with fossil monotremes, or egg-laying mammals. In his inimitable way, Bram had suggested that the problem which came first, the egg or the chicken, was now seen to be linked up with the Darwinian theory, and solved in the person of Dodd.

Nevertheless, Jimmy Dodd entertained a devoted admiration for the memory of the dead scientist. He believed that Bram must have left records of inestimable importance in a cairn before he died. He wanted to find that cairn.

And he knew, what a number of Bram's enemies knew, that the dead scientist had been a morphine addict. He believed that he had wandered out into the snow under the influence of the drug.

Dodd, who shared a tent with Tommy, had raved the greater part of the night about the find.

"Well, but see here, Jimmy, suppose these beetles did inhabit the antarctic continent a few million years ago, why get excited?" Tommy had asked.

"Excited?" bellowed Dodd. "It opens one of the biggest problems that science has to face. Why haven't they survived into historic times? Why didn't they cross into Australia, like the opossum, by the land bridge then existent between that continent and South America? Beetles five feet in length, and practically invulnerable! What killed them off? Why didn't they win the supremacy over man?"

Jimmy Dodd had muttered till he went to sleep, and he had muttered worse in his dreams. Tommy was glad that Captain Storm had given them permission to return to the same spot next morning and look for further fossils, though his own interest in them was of the slightest.

The dogs were being harnessed next morning when the two men hopped into the plane. The thermometer was unusually high for the season, for in the south polar regions the short summer is usually at an end by March. Tommy was sweating in his furs in a temperature well above the freezing point. The snow was crusted hard, the sky overcast with clouds, and a wind was blowing hard out of the south, and increasing in velocity hourly.

"A bad day for starting," said Captain Storm. "Looks like one of the autumn storms was blowing up. If I were you, I'd watch the weather, Tommy."

Tommy glanced at Dodd, who was huddled in the rear cockpit, fuming at the delay, and grinned whimsically. "I guess I can handle her, Captain," he answered. "It's only an hour's flight to where he found that fossil."

"Just as you please," said Storm curtly. He knew that Tommy's judgment as a pilot could always be relied upon. "You'll find us here when you return," he added. "I've counter-manded the order to march. I don't like the look of the weather at all."

Tommy grinned again and pressed the starter. The engine caught and warmed up. One of the men kicked away the blocks of ice that had been placed under the skids to serve as chocks. The plane taxied over the crusted snow, and took off into the south.

The camp was situated in a hollow among the ice-mountains that rose to a height of two or three thousand feet all around. Tommy had not dreamed how strongly the gale was blowing until he was over the top of them. Then he realized that he was facing a tougher proposition than he had calculated on. The storm struck the biplane with full force.

A snowstorm was driving up rapidly, blackening the sky. The sun, which only appeared for a brief interval every day, was practically touching the horizon as it rose to make its minute arc in the sky. A star was visible through a rift in the clouds overhead, and the pale daylight in which they had started had already become twilight.

Tommy was tempted to turn back, but it was only a hundred miles, and Jimmy Dodd would give him no peace if he did so. So he put the plane's nose resolutely into the wind, watching his speed indicator drop from a hundred miles per hour to eighty, sixty, forty—less.

The storm was beating up furiously. Of a sudden the clouds broke into a deluge of whirling snow.

In a moment the windshield was a frozen, opaque mass. Tommy opened it, and peered out into the biting air. He could see nothing.... The plane, caught in the fearful cross-currents that swirl about the southern roof of the world, was fluttering like a leaf in the wind. The altimeter was dropping dangerously.

Tommy opened the throttle to the limit, zooming, and, like a spurred horse, the biplane shot forward and upward. She touched five thousand, six, seven—and that, for her, was ceiling under those conditions, for a sudden tremendous shock of wind, coming in a fierce cross-current, swung her round, tossed her to and fro in the enveloping white cloud. And Tommy knew that he had the fight of his life upon his hands.

The compasses, which required considerable daily adjusting to be of use so near to the pole, had now gone out of use altogether. The air speed indicator had apparently gone west, for it was oscillating between zero and twenty. The turn and bank indicator was performing a kind of tango round the dial. Even the eight-day clock had ceased to function, but that might have been due to the fact that Tommy had neglected to wind it. And the oil pressure gauge presented a still more startling sight, for a glance showed that either there was a leak or else the oil had frozen.

Tommy looked around at Dodd and pointed downward. Dodd responded with a vicious forward wave of his hand.

Tommy shook his head, and Dodd started forward along the cabin, apparently with the intention of committing assault and battery upon him. Instead, the archaeologist collapsed upon the floor as the plane spun completely around under the impact of a blast that was like a giant's slap.

The plane was no longer controllable. True, she responded in some sort to the controls, but all Tommy was able to do was to keep her from going into a crazy sideslip or nose dive as he fought with the elements. And those elements were like a devil unchained. One moment he was dropping like a plummet, the next he was shooting up like a rocket as a vertical blast of air caught the plane and tossed her like a cork into the invisible heavens. Then she was revolving, as if in a maelstrom, and by degrees this rotary movement began to predominate.

Round and round went the plane, in circles that gradually narrowed, and it was all Tommy could do to swing the stick so as to keep her from skidding or sideslipping. And as he worked desperately at his task Tommy began to realize something that made him wonder if he was not dreaming.

The snow was no longer snow, but rain—mist, rather, warm mist that had already cleared the windshield and covered it with tiny drops.

And that white, opaque world into which he was looking was no longer snow but fog—the densest fog that Tommy had ever encountered.

Fog like white wool, drifting past him in fleecy flakes that looked as if they had solid substance. Warm fog that was like balm upon his frozen skin, but of a warmth that was impossible within a few miles of the
