"We've got to be mighty partic'ler with them hosses an' mules," said the Little Giant, "'cause even ef we should reach the mine without 'em we're bound to hev 'em to pack out the gold fur us. I expect we'll hev to ketch an' train 'bout twenty wild hosses, too, ez we'll need 'em fur all the gold that I'm countin' on findin'. Didn't you say thar was that much, young William?"

"I didn't give the exact amount," replied the lad, "nor do I suppose anyone can tell from surface indications how much gold there is in a mine, but from the word my father brought we'll need the twenty wild horses and more."

"O' course we will. I knowed it afore you said it. I've hunted gold fifteen to twenty years without findin' a speck, an' so it stands to reason that when I do find it I'll find a mountain of it."

Although the slope rose steadily, the ground, for the present, was not much cut up, and they were able to ride in comfort. Much of the country was beautiful and parklike. While far below there were endless brown plains, here were great forests, without much undergrowth, and cold, clear streams, running down from the vast snowy dome that always loomed ahead, and that never seemed to come any nearer.

"How high would you say that peak wuz, young William?" asked the Little Giant. "You're an eddicated lad, an' I reckon you know 'bout these things."

"You give me too much credit," laughed Will in reply. "One has to have instruments with which to calculate the height of mountains, and I couldn't do it even if I had the instruments, but I should say from what I've heard about the country and the tales of explorers that the peak we're looking at is about 14,000 feet high."

"I've seen it once before, though from the south," said Boyd, "and I've also met an exploring geographer kind of fellow who had seen it and who told me it rose close on to three miles above the sea. Different Indian tribes have different names for it, but I don't remember any of 'em."

"I think I'll call it the White Dome," said Will, examining it for the hundredth time through his glasses. "From here it looks like a round mountain, though it may have another shape, of course, on the other three sides. It's a fine mountain and as it's the first time I ever saw it I'm going to call it my peak. The forest is heavy and green clear up to the snow line, and beyond that I think I see a vast glacier."

Two days later they made another stop in a sheltered valley through which ran a mountain torrent. The hunter and the Little Giant shot two mule deer and a mountain sheep, and they considered the addition to their larder very welcome, as they had been making large inroads on their stores. The weather, too, had grown so cold that they kept a fire burning both day and night. Far over their heads they heard a bitter wind of the mountains blowing, and when Will climbed out of the valley and turned his glasses toward the White Dome he could not see the peak, it was wrapped around so thoroughly by mists and vapors and falling snow.

They built the fire large and high on the second night, and as they sat around it they held a serious consultation. They feared incessant storms and blizzards if they rose to still higher levels, and attempted to pass around on the lofty slopes of the peak. It would, perhaps, be wiser to follow the torrent, and enter the plains below, braving the dangers of the Sioux.
