170 The Stock Market Crash—dAnd After 
of 600 industrial workers taking periodic health 
examinations through a series of years, shows that

of employees toward their employers. 
Group Insurance 
Group insurance is the means by which health 
care in industry is being rapidly extended. This 
plan has grown amazingly since its beginning in 
1914, until by the middle of 1928, some $7,800,000,~ 
000 of such insurance, covering 6,500,000 workers, 
was being carried by nearly 25,000 employers in all 
lines of industry. Some notion of the savings effected 
through such group insurance, together with the 
sickness prevention method it entails, is given by 
Doctor Quinby, of the Hood Rubber Company, who 
shows that in twelve plants which lack the health 
service, the cases of sickness and non-industrial acci- 
dents causing absences of over two days were 523 
per thousand, against 342 per thousand in his own 
plant, which included the health service. Doctor 
Quinby’s testimony is especially competent, because 
it is backed by six years of well-organized work in 
sickness prevention.
