As an example of the heavy labor for a short while, I chose a model stocking and measured the fatigue of the stocker in spring, summer and winter mainly by the Ogata's urinary protein measuring method and observed the development of the density of urine-protein and the quantity of it excreted per hour before and after the work and also studied the influences affected on the urine-protein by giving much water to the stocker just before the work. In addition, in summer I measured the quantities of Cl in the urine and the perspiration excreted while at work. In winter I measured how the work affected the pulse frequency and the physical strength (the breathing capacity, the strength of the back and the grasping power). The results were as follows: 1) The density of urine-protein and the quantity of it excreted per hour markedly increased with work. 2) The density of urine-protein and the quantity of it excreted per hour shour showed the highest figures just after the work. 3) As compared with the cases in summer, in winter the density of urine-protein and the quantity of it excreted per hour showed a tendency to rapidly recover. 4) Comparing the cases where water was not given, to the cases where water was given just before the work, the urine quantity increased and the density of urine-protein decreased after the work, but the density of urine-protein and the quantity of it excreted per hour increased with work. 5) As water was given, the density of urine-protein and the quantity of it excreted per hour showed a tendency to recover more rapidly than the cases where it was not given. 6) In summer the quantity of urine-Cl excreted per hour decreased after the work and when water was given it showed a tendency to recover more rapidly than the cases where water was not given. 7) In summer loss of Cl was more remakable in the perspiration than in the urine. 8) In summer the Cl quantity of the perspiration while at work conspicuously increased when water was given. 9) After the work, the pulse frequency increased, while the breathing capacity decreased and the grasping power declined in the right hand and in the left hand it did not decline. In the back, however, strength was increased.
