22 THE RELATIVE STRENGTH OF 



Commission on Physical Training a table is given 

 showing the average stature of men at all ages, 

 divided into four classes according to their occupa- 

 tions. These do not correspond exactly with our 

 mortality rates, but they do so roughly and are 

 therefore of interest. 



Class I includes farmers, clergy, lawyers, doctors, 

 teachers, architects, &c. ; all these have a mortality 

 rate of between 3 and 6 per 1000 and come in our 

 mortality groups 3, 4, 5 and 6, except doctors, who 

 are in our group 9. 



Class 1 1 includes law clerks, shop-keepers, dealers 

 in drugs, books, food, drinks, &c., and the majority 

 come in our mortality groups 7 and 8. 



Class III includes gardeners, railway and quarry 

 workers, sailors, miners, &c. ; these also are mostly 

 included in the groups with mortality rates 7 and 8 

 but they vary more than Class II. The mortality 

 rates of Classes 1 1 and III are, however, very similar. 



Class IV includes workers in metal and stone, 

 engravers, printers, &c. who are mostly included in 

 the groups with mortality rates 9 and 10. 



The mortality rates then roughly correspond with 

 these classes — that is to say — 



Class I includes occupations with the lowest 

 mortality rates 3 and 6. 



Classes II and III include occupations with higher 

 mortality rates 7 and 8. 



Class IV includes occupations with still higher 

 rates 9 and 10.
