In some mercantile establishments the trimmer has an electrician at his beck and call, and when a design is ready he simply pushes the button and Mr. Electrician does the rest. But I know that these are exceptional cases, and that in the majority of establishments the trimmer is thrown upon his own resources, and has no one to help him out of his difficulties. And if he is not posted on electrical appliances, his designs are not properly illuminated—a deficiency that annoys the conscientious trimmer as much as it does his employer.

Electricity, properly applied, is an important factor in selling goods through the show window. Therefore the window trimmer who understands wiring his own windows is a more valuable man to his employer than one without this knowledge. I shall endeavor to be plain and avoid the use of unnecessary technical terms.

No doubt your windows have permanent lights. The first thing to do is to have a switch or “cut-out” run in for special work. Any electrician will do this for you in an hour or so, and it saves you from tapping your permanent wires, which should never be done.

Be sure to ascertain the voltage and amperes; or, to be plainer, find out how many lights your “cut-out” will carry.

Before you begin work you must have proper tools to work with, and sufficient supplies to meet any case of emergency.

ELECTRICAL TOOLS.

The following is a list of tools required:

Pair of nippers to cut and twist wire.

Brace and bit.

Screw driver.
