How strategic the period of youth! Then the chiefest forces of life flow together in sensitive conjunction. Then four great gifts like four great rivers unite in one majestic current to bear up the young man's enterprises, and sweep him on to fame and fortune. Opportune are all the days when health spills over at the eye and ear and laughs through the lips. Men worn out are like overshot wheels--the life trickles and the buckets are filled slowly by long rests and frequent vacations. Young men are like undershot wheels--always, by day and night, the water overflows the banks. Each morning the young soul wakens to the supreme luxury of living. The world is a great beaker brimmed with wine of the gods. The truth and beauty of field and forest and river give a pleasure that is exquisite to a keenly sensitive and perfectly healthy youth. Like an Aeolian harp, the slightest breath avails for wakening melody midst its strings. But years multiply cares. Age increases heaviness. Time destroys its own children. The poet says: "In youth we carry the world like Atlas; in maturity we stoop and bend beneath it; in age it crushes us to the ground." For the overtaxed and invalided, the dew-drops do not sparkle as diamonds; the wet grass suggests red flannels and cough sirups. For the nervous the bird's song is a meaningless chatter. For the sickly the clouds are big black water-bottles, though time was when they were chariots for God's angels, curtains for hiding ministering spirits trooping homeward at night, leaving all the air sweetly perfumed. It is the body that grants the soul permission to be happy. To the opportunity offered by health may be added the years lying in front of the young heart like a great estate, as yet unincumbered. Powerful enthusiasms, too, are the inheritance of youth. Noble feelings, fine aspirations then pass through the mind, as in May the perfumed winds from the South pass over the fields. These motives beat upon the mind as steam upon the iron piston. Workmen excavating at Pompeii threw up soil that had been covered for 1,800 years. Exposed to the sun, young trees sprang up. Without the force of light and heat and dew and rain these seeds were dormant or dead. Thus each mind is a dead mind until the full warmth of great impulses quickens the dormant energies. The hopes, the ambitions, the aspirations of youth all conspire to make this a most strategic period. Then all the forces of life unite in a great gulf stream for bearing the soul up and sweeping it forward to new climes and richer shores.
