Chet was just as eager and excited as he could be. Dig appeared to be doubtful of the identity of the moving herd they had spied so far away; nevertheless, he felt that the venture was momentous.

“Shake salt on their tails,” grinned Chet, “as you suggested doing to the antelope.”

“If we get them mad, I reckon they will be. But they are very timid at the approach of man. And if they get started on the run—good-bye! We couldn’t catch them unless our horses were very fresh. That’s why we must take the trip over to their feeding ground easily. We may have to gallop to get a shot.”
