Lynn. There was a rapid rise in 

 the number of industrial employees 

 between 1895 and 1910, and an equal- 

 ly sharp decline between 1920 and 

 1933. The upward trend of popula- 

 tion stopped in 1920 after which there 

 was a slight decline. The number of 

 industrial establishments increased 

 rapidly between 1855 and 1895. It 

 was slightly lower in 1933 than in 

 1905. 



Malden. The trend of total popu- 

 lation has been upward throughout 

 the period beginning with 1845. The 

 number of industrial employees rose 

 sharply between 1910 and 1920. A 

 considerable decline occurred in the 

 period of depression. The number of 

 establishments has risen somewhat 

 since 1905. 



Marlboro. After an irregular rise 

 the number of industrial employees 

 began its decline in 1910. The total 

 population has not changed greatly 

 since 1895, being now only slightly 

 higher. The peak in number of estab- 

 lishments was reached in 1885. 



Medford. There has been a rapid 

 increase in total population, especially 

 since 1910, evidently promoted by ele- 

 ments other than industrial growth. 

 Industrial employment reached its 

 peak as early as 1855, and in 1933 it 

 was at about the same level as in 1895. 

 There was, however, an upward trend 

 in industrial employment as well as 

 in the number of industrial establish- 

 ments between 1905 and 1927.
