       At the end of the half-hour we dropped our packs.  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  those words meant a good deal. For s-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 s scourges. This rigidity speedily exhausts the vital force.

       So much for the philosophy of it. Its practical side might be infinitely extended. smen 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 cl 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  day. Bristol said he dropped finally as though he had been struck on the head. The sman had thereupon built him a little fire, made him as comfortable as possible with both coats, and hiked for istance. I once went into the s with a prominent college athlete. We walked rather  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.

       It comes at the last to be entirely a matter of experience. Any man can walk in the s all day at some gait. But his speed will depend on his skill. It is exactly like making your way through heavy, dry sand. As long as you restrain yourself to a certain leisurely plodding, you get along without extraordinary effort, while even a slight increase of speed drags fiercely at your feet. So it is with the s. As long as you walk slowly enough, so that you can pick your footing and lift aside easily the branches that menace your face, you will expend little nervous energy. But the slightest pressing, the slightest inclination to go beyond what may be called your physical foresight, lands you immediately in difficulties. You stumble, you break through the brush, you shut your eyes to avoid sharp switchings. The reservoir of your energy is open full cock. In about an hour you feel very, very tired.

       This principle holds rigidly true of every one, from the softest tenderfoot to the expertest forest-runner. For each there exists a normal rate of travel, beyond which are penalties. Only, the forest-runner, by long use, has raised the exponent of his powers. Perhaps as a working hypothesis the following might be recommended: One good step is worth six stumbling steps; go only fast enough to ure that good one.

       You will learn, besides, a number of things practically which memory cannot summon to order for instance here. "Brush slanted across your path is easier lifted over your head and dropped behind you than pushed aside," will do as an example.
