lves at least two coatings of asphaltum paint. This will prevent
rotting by the acid.

The floor of a battery repair shop is, at best, a wet, sloppy affair,
and if a lead drainage trough is too expensive, there should be a
drain in the center of the floor if the shop is small, and several if
the shop is a large one. The floor should slope toward the drains, and
the drain-pipes should be made of glazed tile.

To keep the feet as dry as possible, rubbers, or even low rubber boots
should be worn. Sulphuric acid ruins leather shoes, although leather
shoes can be protected to a certain extent by dipping them in hot
paraffine.

[Fig. 135 Wooden grating on shop floor to give dry walking
surface for the repairman]

A good plan is to lay a wooden grating over the floor as shown in
Figure 135. Water and acid will run down between the wooden strips,
leaving the walking surface fairly dry. If such a grating is made, it
should be built in sections which may be lifted easily to be washed,
and to permit washing the floor. Keep both the grating and the floor
beneath covered with asphaltum paint to prevent rotting by acid. Once
a week, or oftener, if necessary, sweep up all loose dirt and then
turn the hose on the floor and grating to wash off as much acid as
possible. When the wood has dried, a good thing to do is to pour on
the floor and grating several pails of water in which washing soda or
ammonia has been dissolved.

Watch your floor. It will pay-in better work by yourself and by the
men working for you. Have large earthenware jars set wherever
necessary in which lead drillings, old plates, old connectors, old
separators, etc., may be thrown. Do not let junk cases, jars,
separators, etc., accumulate. Throw them away immediately and keep
your shop clean. A clean shop pleases Your customers, --and satisfied
customers mean success.

On the following pages a number of shop layouts are given for both
large and small shops. The beginner, of course, may not be able to
rent even a small shop, but he may rent part of an established repair
shop, and later rent an entire shop. A man working in a corner of an
established service must arrange his equipment according to the space
available. Later on, when he branches out for himself, he should plan
his shop to got the best working arrangement. Figure 136 shows a
suggested layout for a small shop. Such a layout may have to be
altered because of the size and shape of the shop, and th
