The distance from the shelter of the brush to the fire was not very great, and could have been covered speedily only for the desire on the part of the scouts to take the man by surprise.

Step Hen spoiled this by an unfortunate stumble, which was rather singular, because as a rule he had proved sure-footed. It chanced, however, that Step Hen was watching the reclining figure by the fire so closely that he did not notice some obstruction lying in his path, so that the first thing he knew he caught his toe, and measured his full length on the ground.

Of course that spoiled the surprise part of the game. Thad knew it instantly, as the tramp’s head came up, and accordingly he uttered a quick command.

“Rush him!”

With that each scout jumped forward, eager to be the first to close in on the enemy. Those who had guns displayed them threateningly, while the others waved their clubs in a way that needed no explanation as to what use they expected to make of the same presently.

If the actions of the invaders of the hobo camp were rapid the same could be said concerning the movements of the lone inmate. He must have realized the desperation of his position the very instant he sighted those advancing boys in khaki, with such a ferocious display of various weapons of defense and offense, for like a flash he scrambled to his feet.

As it was hardly to be expected that the tramp had prepared himself against a surprise like this, the chances were he acted solely from impulse.

Giraffe fully expected he would try and go around their outermost guards, and with memories of similar tactics employed on the gridiron he changed his course somewhat in order to cut off this flight.

It was a mistake, for the fellow never once endeavored to flee. Instead of this he leaped over to a pile of rocks that chanced to lie close by, forming a species of pyramid. The boys saw him throw himself into the midst of this, even while they were rushing forward, though they could not anticipate what his scheme might be.

Events are apt to happen with lightning-like rapidity under such conditions as these, and the first thing the boys knew there was a sharp report as of a pistol, and a puff of smoke burst from the pile of rocks that thrilled them to the core.
