Tom had learnt something of the elements of geology, and could form an idea of the processes by which the strange country at which he was looking had been formed.
"That's Frémont's Buttes," the Indian said presently, pointing to a flat-topped hill that towered above the others ahead.
"Why, I thought you said it was a fifty-mile ride to-day, Jerry, and we can't have gone more than half that."
"How far do you suppose that hill is off?"
"Three or four miles, I should think."
"It is over twenty, lad. Up here in the mountains the air is so clear you can see things plain as you couldn't make out the outlines of down below."
"But it seems to me so close that I could make out people walking about on the top," Tom said a little incredulously.
"I dare say, lad. But you will see when you have ridden another hour it won't seem much closer than it does now."
Tom found out that the miner was not joking with him, as he at first had thought was the case. Mile after mile was ridden, and the landmark seemed little nearer than before. Presently Hunting Dog said something to the chief, pointing away to the right. Leaping Horse at once reined in, and motioned to his white companions to do the same.
"What is it, chief?" Jerry asked.
"Wapiti," he replied.
"That is good news," the miner said. "It will be lucky if we can lay in a supply of deer flesh here. The less we shoot after we get through the pass the better. Shall we go with you, chief?"
"My white brothers had better ride on slowly," Leaping Horse said.
"Might scare deer. No good lose time."
Tom felt rather disappointed, but as he went on slowly with Jerry, the miner said: "You will have plenty of chances later on, lad, and there is no time to lose in fooling about. The red-skins will do the business."
Looking back, Tom saw the two Indians gallop away till they neared the crest of a low swell. Then they leapt from their horses, and stooping low went forward. In a short time they lay prone on the ground, and wriggled along until just on the crest.
"I reckon the stag is just over there somewhere," Jerry said. "The young red-skin must have caught sight of an antler."
They stopped their ponies altogether now, and sat watching the Indians. These were half a mile away, but every movement was as clearly visible as if they were but a hundred yards distant. The chief raised himself on his arms and then on to his knees. A moment later he lay down again, and they then crawled along parallel with the crest for a couple of hundred yards. Then they paused, and with their rifles advanced they crept forward again.
"Now they see them," Jerry exclaimed.
The Indians lay for half a minute motionless. Then two tiny puffs of smoke darted out. The Indians rose to their feet and dashed forward as the sound of their shots reached the ears of their companions.
"Come on," Jerry said, "you may be sure they have brought down one stag anyhow. The herd could not have been far from that crest or the boy would not have seen the antler over it, and the chief is not likely to miss a wapiti at a hundred yards."
Looking back presently Tom saw that the Indian ponies had disappeared.
"Ay, Hunting Dog has come back for them. You may be sure they won't be long before they are up with us again."
In a quarter of an hour the two Indians rode up, each having the hind-quarters of a deer fastened across his horse behind the saddle, while the tongues hung from the peaks.
"Kill them both at first shot, chief?" Jerry asked; "I did not hear another report."
"Close by," the chief said; "no could miss."
"It seems a pity to lose such a quantity of meat," Tom remarked.
"The Indians seldom carry off more than the hindquarters of a deer, never if they think there is a chance of getting more soon. There is a lot more flesh on the hindquarters than there is on the rest of the stag. But that they are wasteful, the red-skins are, can't be denied. Even when they have got plenty of meat they will shoot a buffalo any day just for the sake of his tongue."
It was still early in the afternoon when they passed under the shadow of the buttes, and, two miles farther, came upon a small lake, the water from which ran north. Here they unsaddled the horses and prepared to camp.
CHAPTER V
IN DANGER
There were no bushes that would serve their purpose near the lake; they therefore formed their camp on the leeward side of a large boulder. The greatest care was observed in gathering the fuel, and it burned with a clear flame without giving out the slightest smoke.
"Dead wood dries like tinder in this here air," the miner said. "In course, if there wur any red-skins within two or three miles on these hills they would make out the camp, still that ain't likely; but any loafing Indian who chanced to be hunting ten or even fifteen miles away would see smoke if there was any, and when a red-skin sees smoke, if he can't account for it, he is darned sartin to set about finding out who made it."
The horses fared badly, for there was nothing for them to pick up save a mouthful of stunted grass here and there.
"Plenty of grass to-morrow," the chief said in answer to a remark of Tom as to the scantiness of their feed. "Grass down by Buffalo Lake good."
Early the next morning they mounted and rode down the hills into Big Wind River valley. They did not go down to the river itself, but skirted the foot of the hills until they reached Buffalo Lake.
"There," the chief said, pointing to a pile of ashes, "the fire of my white brother." Alighting, he and Hunting Dog searched the ground carefully round the fire. Presently the younger Indian lightly touched the chief and pointed to the ground. They talked together, still carefully examining the ground, and moved off in a straight line some fifty yards. Then they returned.
"Indian here," Leaping Horse said, "one, two days ago. Found fire, went off on trail of white men."
"That is bad news, chief."
"Heap bad," the Indian said gravely.
"Perhaps he won't follow far," Tom suggested.
The Indian made no answer. He evidently considered the remark to be foolish.
"You don't know much of Indian nature yet, Tom," the miner said. "When a red-skin comes upon the trail of whites in what he considers his country, he will follow them if it takes him weeks to do it, till he finds out all about them, and if he passes near one of his own villages he will tell the news, and a score of the varmint will take up the trail with him. It's them ashes as has done it. If the chief here had stopped with them till they started this would not have happened, for he would have seen that they swept every sign of their fire into the lake. I wonder they did not think of it themselves. It was a dog-goned foolish trick to leave such a mark as this. I expect they will be more keerful arterwards, but they reckoned that they had scarce got into the Indian country."
"Do you think it was yesterday the red-skin was here, or the day before, chief?"
"Leaping Horse can't say," the Indian replied. "Ground very hard, mark very small. No rain, trail keep fresh a long time. Only find mark twice." He led them to a spot where, on the light dust among the rocks, was the slight impression of a footmark.
"That
