TWO:Jim Humphreys's shot had given new restlessness to the boys. They did not at all believe in Shorty's diagnosis of the situation. There must be more men lurking over there whence all that murderous shooting had come only a little while ago. Jim Humphreys was more than probably right. One after another of them quietly slipped away from the fire with his gun and made his way down to Jim Humphreys's post, which commanded what seemed to be a crossing of the creek. They stood there and scanned the opposite bank of darkness with tense expectancy. They had their ears tuned up to respond to even the rustle of the brown, dry leaves on the trees and the murmur of the creek over the stones. They even saw the white birches move around from place to place and approach the water, but Shorty's dire threat prevented their firing until they got something more substantial.The teamsters sprang up like jacks-in-the-box, and ran with all the power of their legs. By the time the explosion came they were hundreds of yards away.
