The importance of electricity in factory work cannot be over-estimated. A shop fully equipped with electric machinery is the best possible kind of shop for employee as well as for the owner. Motor-driven machines are the safest possible kind, while absence of overhead shafting and dangerous belts mean health as well as security. In the electric shop, motor-driven blowers carry fumes and dust away from the worker and bring fresh air in. Electrically driven machinery is now regarded as the standard machinery. In the various vocational schools in New York City at present both boys and girls are taught to operate electrically driven machines, it being assumed that those will be what the pupils will be called upon to operate when they leave the school for the shop.
