ing and
proper size of needle, thread, etc. Do not make any adjustments
unless you are sure you know how. These adjustments require
patience, as the adjusting screws must be turned a very little
at a time to note the effect produced. Do not run the machine at
too high a speed as this will shorten its life.

When putting a motor on a foot-power machine be sure that the
old machine is not over-speeded.

If your machine is provided with a foot release be sure that the
release entirely cuts off current, otherwise the motor will run
very hot.

FLAT IRON

There are several makes of electric irons which do excellent
work and have a long life. The standard sizes are 3, 6 and 8
pounds. The 6-pound iron is best adapted for general household
use.

If the iron becomes too hot, disconnect the lead from the iron.
In case the terminals become corroded, rub them with a piece of
fine emery cloth to remove corrosion. If the contacts become
corroded or bent they should be replaced.

ELECTRIC LAMPS

Mazda lamps are the most efficient lamps obtainable and their
use is recommended for all classes of service. Your electric
bills depend upon the watts per lamp and the number of hours of
use. Note in the following table that the Mazda lamps give on
the average two and one-half times as much light for the same
cost as the Gem carbon lamps. The column "Cost of current per
month" gives the cost of burning one lamp one hour per day for
one month at the maximum rate of nine cents per K. W. H.
