1895 = 100 



Peabody. With population and 

 number of industrial employees on an 

 upward trend, the latter showed a 

 very sharp increase from 1895 to 1920 

 after which it went into a considerable 

 decline. The number of industrial 

 establishments was at its peak in 

 1885, and in 1933 kept at about the 

 same level as in 1905.

Pittsfield. The upward trend in 

 population and number of industrial 

 employees has been maintained 

 through the entire period, except that 

 the latter showed a sharp decline after 

 1927 coinciding with the period of de- 

 pression. The number of industrial 

 establishments increased from 1905 

 to 1920 and declined afterwards. 



Quincy. The population increased 

 rapidly through the entire period; and 

 the number of industrial employees, 

 after an extremely sharp rise, largely 

 due to activities of war industries be- 

 tween 1910 and 1920, broke down 

 thereafter into a rapid decline, and in 

 1933 was at about the same level as 

 in 1895. The number of industrial 

 establishments was only slightly lower 

 in 1933 than in 1905.
