read; that is, from right to left. In case the indicator does not point
directly to a number, but is somewhere between two numbers, read the
number that it is leaving. For example, in Fig. 2, the indicator in the
right-hand dial points to figure 4; therefore, this number should be put
down first. In the second dial, the hand lies between and 1, and as it
is leaving 0, this number should be read and placed to the left of the
first one read, which gives 04. The hand on the third dial points
exactly to 6; so 6 should be read for this dial and placed directly
before the numbers read for the first and second dials, thus, 604. On
the fourth and last dial, the indicator is between 4 and 5; therefore 4,
which is the number it is leaving should be read and used as the first
figure in the entire reading, which is 4,604.

After the reading of the electric meter has been ascertained, it is a
simple matter to determine the electricity consumed since the last
reading and the amount of the bill. For instance, assume that a meter
registers the number of kilowatt-hours shown in Fig. 2, or 4,604, and
that at the previous reading it registered 4,559. Merely subtract the
previous reading from the last one, which will give 45, or the number of
kilowatt-hours from which the bill for electricity is computed. If
electricity costs 3 cents a kilowatt-hour, which is the price charged in
some localities, the bill should come to 45 X .03 or $1.35.


PRINCIPLE OF STOVES

62. Before stoves for cooking came into use in the home, food was cooked
in open fireplaces. Even when wood was the only fuel known, a stove for
burning it, called the Franklin stove, was invented by Benjamin
Franklin, but not until coal came into use as fuel were iron stoves
