Sitting. — With the striking exception of Pea, who reports an average 

 of bat 5f hours sitting, and Gul, who reports but 7f hours, the 

 men in Squad A showed, on the average, a sitting value not far from 

 10 to 12 hours. 



Walking. — The records for walking vary considerably; most of the 

 men averaged not far from 3 to 4 hours. In striking contrast to this 

 are, however, the values for Gul of 7 hours, Mon of 7^ hours, and 

 Pea of 9 hours. Although every effort was made to secure as accurate 

 and objective records for these men as possible, it is clear that errors — 

 indeed, serious errors — crept into these estimates, for an examination 

 of the pedometer records for Squad A from January 14 to February 2 

 shows that while the correlation between the number of hours esti- 

 mated for walking and the miles recorded on the pedometer is reason- 

 ably constant with most of the men, we have several wide differences. 



Thus Gul reported an average of 7 hours per day walking, while the 

 pedometer showed but 10 miles. Mon reported 7| hours with a mile-

*A recent operation prevented Tom from engaging in strenuous exercise and called for a larger 

 percentage of hours sitting. "Endurance test" and motion pictures on Feb. 1.
