His voice, great in volume though it was, was all but drowned in the shriek and roar of the blast. The lightness that had afforded us so much enjoyment in still air now became a source of grave danger, for we could not keep our feet in the fury of the tempest.

"Merciful powers!" roared Popham, as he and Meigs were driven against each other with a terrific impact.

Although sorely put to it to keep myself from being blown away, I managed to cling to a rock and watch the weird gyrations of the two millionaires. Their collision had caused them to lose their footing, and, clinging desperately to each other, they were hurled back and forth, touching the ground now and then, only to rebound from it like rubber balls. And all the time this ground-and-lofty tumbling was going on both men were whooping frantically for some one to come to their aid.

I was too hard beset to think of leaving my place of temporary refuge, and it was only when I saw the professor and Markham, their right hands clasped, staggering toward the two men, that I made up my mind to join them. Three of us, in a chain, might be able to do something toward rescuing Popham and Meigs.

Breathing deep, like a swimmer about to plunge through a whirlpool, I cast myself adrift and allowed the wind to drive me in the direction of the professor and Markham. No matter how strongly I braced backward against the blast, every time I lifted a foot I was hurled onward and almost overturned. Finally, more by good luck than anything else, I came close enough to catch the professor's hand.

"Popham and Meigs will be killed if we can't get to them!" shouted Markham.

There were eddies in the wind, like those in the swift current of a stream, and Popham and Meigs had become entangled in them. Had they been blown off on a straightaway course, they would long since have been too far away for us to do anything toward laying hands on them and getting them upright.

The professor had taken note of the gyratory movements of our hapless companions, and he called upon Markham and me to plant ourselves as firmly as possible and remain in our present positions. This was easier said than done; yet, by calling upon every ounce of our reserve strength, we contrived, after a fashion, to keep our places.

Popham and Meigs were bounding and leaping through the arc of a great circle. All we had to do was to remain where we were and wait for them.

They came to us in mid-air, and we had literally to reach up and pull them down. For a space the five of us were tangled in an indiscriminate heap, our united weight offering greater resistance to the wind and giving us an opportunity to rest and collect our scattered wits.
