To W. B. McDonald, superintendent of the People's Light and Power company, Chicago, must be given the credit of producing an arc lamp hanger board made entirely of glass, having a glass back or support, as well as glass insulating knobs. The device is known as the McDonald glass hanger board. This board can always be relied upon as a perfect insulator, and always looks bright and clean. This specialty is placed on the market by the Electric Appliance company, Chicago, which will be glad to quote prices on application.
