On long distances wire can be saved by using a grounded circuit, which is done as follows : Drive a piece of iron into the earth, from four to five feet down, connect a wire to the iron driven into the ground by wrapping the bare wire tightly around the iron. This ground wire is then run to the battery and connected to the zinc side. A second wire is run from the carbon side of the battery to one side of the push-button; a second wire runs from the push-button to wherever the bell is placed; a wire is run from the bell to a second ground iron, and attached or connected to the ground iron, the same as the first ground connection was made. Where long distances are to be connected, namely, from house to stable, factory or any other building, this way of doing electric bell work is frequently done. All wires that are outside of buildings should be fastened on to porcelain or glass insulators, and never be nailed against brick or stone walls, or any frame buildings; always use ! insulators, and have wires clear of all places.

It is recommended for electric bell work that no lighter wire than what is known in the trade as No. 16 be used, and that the wire have a good insulation or covering.
