CHAPTER XIII.
DICK'S GREAT EXPLOIT It was a singular and weird sound, the blowing of the great cow's horn on the mountain, and then the distant reply from another horn as great.
It was both significant and sinister, such an extraordinary note that, despite Dick's experience and courage, his hair lifted a little.

He was compelled to look back at the camp and the coals of the fire yet glowing to reassure himself that everything was normal and real.
"I wish there wasn't so much snow," said Shepard, "then the sergeant, Mr.Reed and myself could scout all over the country around here, mountains or no mountains." They were joined at that moment by Reed, the long mountaineer, who had also been listening to the big horns.
"That means them gorillers, shore," he said.

"We've got some p'ison people uv our own, an' when the gorillers come in here they j'ined 'em, and knowin' ev'ry inch uv the country, they kin guide the gorillers wharever they please." "You agree then with Mr.Shepard that these signals are made by Slade and Skelly's men ?" asked Dick.
"Shorely," replied the mountaineer, "an' I think they're up to some sort uv trick.

It pesters me too, 'cause I can't guess it nohow.

I done told the colonel that we'd better look out." Colonel Winchester joined them as he was speaking, and listened to the double signal which was repeated later.
