[Vol. XV, 



The weekly salary range of this group of men examined individually runs up to $65 for 

 the whites and $40 for the negroes, with the median of the whites earning $16.60 and the 

 median of the negroes $15. It can be observed from table 343 that 50.2 per cent of the negroes 

 and 41.8 per cent of the whites had a weekly wage of less than $15. 



Table 343. — Percentage distribution of weekly wages of whites and negroes. 



Over 60 per cent of both whites and negroes were, as might be expected, farmers, laborers, 

 or miners. More than half of these were farmers. The mental ages of the men in these 

 occupations vary only slightly. The median mental ages are given in table 344. 



Table 344. — Median of mental ages by occupation. 



It is of interest that 69.9 per cent of the whites and 83.4 per cent of the negroes held only 

 one job during the year previous to their entrance into the Army; 18.3 per cent of the whites 

 and 11.9 per cent of the negroes held two during the year. As many as 15 different jobs were 

 held in that year by the whites, while 7 was the highest number recorded for the negroes.

 10 years or under.
