MANY ARE SYCCUMBING

From the Chicago Tribune.
 I-neounted millions of people have per ished and are perishing for no other req son than that they are tired. Numberless hosts of sad mortals have died and are dying from no disease save chrome eN- haustion. And not only human beings bu animals and beautiful birds.
 pr. Angelo Mosso, the eminent Italian of Turin University, who has studied the condition and effects of fatigue as perhaps no one else, tells of watching the hocks of birds coming home from the south for the summer, beating helpless asalnst the rockbound shores of lovely Italy after thousands of miles of flight too weary to enjoy the land they flew so far to reach too weary to live after they have toiled so bravely to find place to live.
 There are birds which travel more than 5000 miles every spring, from South Al req, Polynesia, and Australia, in order to reach the polar regions and in autumn return to the winter quarters in the same way. Every year the martins travel from the North Cape to the Cape of Good Hope, and vice versa.
 But these prodigIous labors are not achieved without prodigious fatigue In the open sea pigeons have been observed on the waves with outspread wings, and in these birds this was certainly a sign of oVerpowering fatigue. Trustworthy sailors are said to declare that the quail. when excessively weaued settles on the water and rests for some time, then takes flight once more, and continues it's route.
 Birds Care for the Tired Ones.
 Prof Mosso has somewhere read that among the birds which are strongest ill the wings some have been observed at sea bearing on their backs a tired little one, which has thus found safety in desperate situation.
 In order better to study the conditions of fatigue and the changes Tn the organ- isms of birds caused by a long journey Dr. Mosso had house for carrier pig cons fitted up in his laboratory. which, like the majority of those in Italian unl- versailles, is situated in an old convent When pigeons are set free in Bologna or Auenea, about 300 miles distant, the sta- ton master sends Dr. Mosso a telegram At the time the birds may be expected he goes up to the neighboring church tower and there awaits their coming, telescope in hand.
 They come quickly. One has scarcely time to perceive them before they are on the roof When placed beside the oth- CTS the fatigued pigeons can easily be distinguished, for they sit crouched down and motionless, nor do they fly about and play for several hours. The muscles of the pigeons which have performed the journey were darker than those of the birds that had remained at home.
 The professor exposed the brains of the four dead birds that had performed the journey from Bologna to Turin and com pared them with those of the normal birds The difference in hue was so evi- dent that everybody in the laboratory noticed it. In the fatigued birds the brain was pale, almost bloodless.
 This fact, the scientific investigator be- lieves, can explain why the quails on their arrival from Africa do not see so well as usual, but dash themselves against the rocks, and why people are incapable of doing brain work after great fatigue.
 Human Beings Die of Fatigue.
