Cool site, one nit:

How come the first photo under "Manufacturing, Light" claims it's from 1918, but the picture has flourescent light fixtures in it? Maybe the workers pictured _started_ working in 1918?

The caption says:

Gilbert & Bennett Mfg. Co
One hundred years of progress 1818-1918
1918
self-published/ Georgetown CN
pg. 83
The 2 employees with the longest continous service at the Blue Island mill are James Jones at the left and Frank Kedrowski at right both with 48 years of service.
