"Not this trip," spoke Tom, grimly. "We'll try for the gold, first."
"Yes, an' I'm goin' t' begin diggin' right away!" exclaimed Abe, as he turned back into the airship, and came out again with a pick and shovel, a supply of which implements had been brought along. The others followed his example, and soon the ice chips were flying about in a shower, while the sun shining on them gave the appearance of a rainbow.
"Look at those Indians watching us," remarked Ned to Tom, as he paused in his chipping of the frozen surface. The young inventor glanced up toward the distant plateau where a fringe of dark figures stood. The natives were evidently intently watching the gold-seekers.
"Do you think there's any danger from them. Abe?" asked Tom.
"Not much," was the reply. "They made trouble for me an' my partner, but I guess th' airship has scared 'em sufficient, so they won't come snoopin' down here," and Abe fell to at his digging again.
Mr. Damon was also vigorously wielding a pick, but Mr. Parker like the true scientist he was, had renewed his observations. Evidently the gold had no attractions for him, or, if it did, he preferred to wait until he had finished his calculations.
Vigorously the adventurers wielded their implements, making the ice fly, but for an hour or more no gold was discovered. Mr. Damon, after picking lightly at a certain place, would get discouraged, and move on to another. So did Ned, and Tom, after going down quite a way, left off work, and walked over to one of the big ice caves.
"What's up?" asked Ned, resting from his labors.
"I was thinking whether it would be safe to put the RED CLOUD in this ice cave for a shelter," replied Tom. "There may come up a hail storm at any time, and damage it. The caves would be just the place for it, only I'm afraid the roof might collapse."
"It looks strong," said Ned. "Let's ask Mr. Parker his opinion."
