What we want is suppleness, chest expansion, resistive force, and endurance; and these do not come from great bulging knots of muscle nor from extraordinary feats of strength. Rapid shifts from severe training to a life of ease and indulgence is not Nature's process. It is not the way in which she carries on her work. Every step she makes is a little one. She seems never to reckon time as an essential in her economy. We should heed the lesson. The man who eats, drinks, and neglects all care of himself for a year, and then rushes madly into a period of severe physical exercise and reduction, may at the end of the month, if he possesses sufficient vitality, come out feeling fine. But if he repeats the process of letting himself go, Nature puts on the fat more and more and a second severe reduction becomes necessary. And it is only a question of time as to the exhaustion of any man's vitality through these extremes. TIME THE GREAT ELEMENT Any one who has had the opportunity of talking with the men in authority who are bearing the burden of fitting a nation for the present emergency cannot fail to be impressed with the fact that time is the great element. We must really prepare our men, we must make them fit in the shortest space of time that will accomplish the result. And we must conserve our man-power. It is no longer a question of putting on such severe work as shall weed out all but the physical giants; we are not trying (as seemed to be the idea in the first Plattsburg camps, before the war) to make the going so stiff as to leave us only 50 per cent. of hardened men. We want every man who can be brought along rapidly into condition, and not the strongest only. Hence the problem takes on a new phase. We all recognize that the quality and previous training of the men this country is sending into service have a very potent bearing upon the length of time required to make fighters of them. For, after all, the man whose training and discipline have been along a kindred line becomes serviceable much earlier than the man who has to acquire the necessary spirit and quality. No one who has listened to the coaches of our various college teams, or who has read either the preliminary prospects of a game or the account of it afterward, but must have been impressed with the continual repetition of emphasis upon the "fighting spirit." Hence, when our athletes flock almost _en masse_ to the colors, it means that we are enlisting a large number of picked men who have been in training both mentally and physically, and who, under discipline, will make obedient, courageous, and enthusiastic fighters. But a large number of these have been out of college or out of strenuous athletics a year or two, or longer, and they need physical conditioning to get back.
