The Phillips Factory, and an 1895 shot of the factory's employees.
Alice VanAtta recalled of the factory, "The whistle sounded at six every morning except on Sundays and national holidays to awaken the considerable force of employees. It blew again at seven to call them for work. The whistle blew at noon to release them for an hour for dinner, again at one to call them back, and once more at six o'clock when the day was over. This meant a ten hour working day, six days a week, fifty-two weeks per year. Each factory hand received six dollars per week and a turkey at Thanksgiving." --Reflections on a Bygone Era
