It is difficult to determine as to the interior character of the electrical and bell work, but the adequacy of the equipment should be considered by noting the use or omission of wall switches, base plugs, dresser outlet lights, sufficient illumination in all rooms, and the use of proper panel boards and boxes in each apartment. It is easy to detect whether paraffine or rubber covered wire has been used for the bell work, the use of the latter showing that the best material possible has been employed. The sufficiency of the equipment of bells and annunciators, where necessary, should be noted. The use of a handsome and substantial push button at the entrance door is a slight indication of the care or carelessness used in equipping the house.
