With a rush the natives, led by the Fogers, came on. They were yelling now. An instant later they began firing their guns.
"It's a fierce attack!" cried Tom. "Into the ice cave for shelter! We can cover the gold mine from there. I'll get my electric gun!"
CHAPTER XXIV
THE WRECK OF THE AIRSHIP
Almost before our friends could retreat into the cave which now sheltered the RED CLOUD, the attacking natives opened fire. Fortunately they only had old-fashioned, muzzle-loading muskets, and, as their aim was none of the best, there was comparatively little danger. The bullets, however, did sing through the fast-gathering darkness with a vicious sound, and struck the heavy sides and sloping front of the ice cave with a disconcerting "ping!"
"I don't hear Andy or his father firing!" called Tom, as he and the others returned the fire of the savage Indians. "I could tell their guns by the sharper reports. The Fogers carry repeating rifles, and they're fine ones, if they're anything like the one we took from Andy, Ned."
"That's right," agreed Tom's chum, "I don't believe Andy or his father dare fire. They're afraid to, and they're putting the poor ignorant natives up to it. Probably they hired them to try to drive us away."
This, as they afterward learned, was exactly the case.
The battle, if such it could be called, was kept up. There was about a hundred natives, all of whom had guns, and, though they were slow to load, there were enough weapons to keep up a constant fusilade. On their part, Tom and the others fired at first over the heads of the natives, for they did not want to kill any of the deluded men. Later, though, when they saw the rush keeping up, they fired at their legs, and disabled several of the Eskimos, the electric gun proving very effective.
