Now I must be permitted to celebrate by a little the pluck of Dick. He was quite unused to the tump-line, comparatively inexperienced in woods-walking, and weighed but one hundred and thirty-five pounds. Yet not once in the course of that trip did he bewail his fate. Towards the close of this first afternoon I dropped behind to see how he was making it. The boy had his head down, his lips shut tight together, his legs well straddled apart. As I watched he stumbled badly over the merest twig.

"Dick," said I, "are you tired?"

"Yes," he confessed frankly.

"Can you make it another half-hour?"

"I guess so; I'll try."

At the end of the half-hour we dropped our packs. Dick had manifested no impatience--not once had he even asked how nearly time was up--but now he breathed a deep sigh of relief.

"I thought you were never going to stop," said he simply.

From Dick those words meant a good deal. For woods-walking differs as widely from ordinary walking as trap-shooting from field-shooting. A good pedestrian may tire very quickly in the forest. No two successive steps are of the same length; no two successive steps fall on the same quality of footing; no two successive steps are on the same level. Those three are the major elements of fatigue. Add further the facts that your way is continually obstructed both by real difficulties--such as trees, trunks, and rocks--and lesser annoyances, such as branches, bushes, and even spider-webs. These things all combine against endurance. The inexperienced does not know how to meet them with a minimum of effort. The tenderfoot is in a constant state of muscular and mental rigidity against a fall or a stumble or a cut across the face from some one of the infinitely numerous woods scourges. This rigidity speedily exhausts the vital force.

So much for the philosophy of it. Its practical side might be infinitely extended. Woodsmen are tough and enduring and in good condition; but no more so than the average college athlete. Time and again I have seen men of the latter class walked to a standstill. I mean exactly that. They knew, and were justly proud, of their physical condition, and they hated to acknowledge, even to themselves, that the rest of us were more enduring. As a consequence they played on their nerve, beyond their physical powers. When the collapse came it was complete. I remember very well a crew of men turning out from a lumber camp on the Sturgeon River to bring in on a litter a young fellow who had given out while attempting to follow Bethel Bristol through a hard day. Bristol said he dropped finally as though he had been struck on the head. The woodsman had thereupon built him a little fire, made him as comfortable as possible with both coats, and hiked for assistance. I once went into the woods with a prominent college athlete. We walked rather hard over a rough country until noon. Then the athlete lay on his back for the rest of the day, while I finished alone the business we had come on.

Now, these instances do not imply that Bristol, and certainly not myself, were any stronger physically, or possessed more nervous force, than the men we had tired out. Either of them on a road could have trailed us, step for step, and as long as we pleased. But we knew the game.
