en by bending over and looking between the
legs. Plant a peg at this point and the distance from the peg to the
base of the object is roughly equal to the height.

Sound travels at the rate of 365 yards every second, as many yards as
there are days in the year. By counting the seconds between seeing the
flash from a gun, or the steam puff from a locomotive and hearing the
sound of the explosion or whistle it is possible to figure the length of
the distance between yourself and the gun or locomotive.

It is said that the number of seconds between a flash of lightning and
the thunder will give the distance between you and the place where the
lightning struck.

We use weighing machines or scales in buying food, so that we may
compare the actual amount of food we buy with a standard weight,
otherwise there would be much confusion and business could not be
carried on between peoples. For this reason we use pint, quart, peck
and bushel measures, all of which are regulated by law as to the amount
they hold.

There are some people who have a true feeling or sense for weight and
can tell almost to an ounce the weight of a parcel by lifting it. Others
have a good memory and can tell the weight of a quantity by looking at
it. Others know distance and can estimate it correctly without use of
rule or measure, and likewise judge numbers.

Very few people have this ability naturally, but many have acquired it
by practice and patience and a Scout can do so: she will find many times
that this particular form of knowledge whether in or out of doors is of
benefit.

How often a housekeeper wishes she could tell about how much material to
buy for this or that purpose without getting the yard stick and
measuring. The seamstress and dressmaker must judge length and width and
even height, and the cook constantly has need of a sense of quantity and
size. The photographer, the pioneer, the camper, all must know
measurements. This matter of judging is something we are called upon to
do much more than we have realized. The point is how can we learn the
trick? We should start with something we know and compare to it
something whose size we do not know. This is where knowing your personal
measurement will be of value. Always prove when practicing your idea,
otherwise you will not improve your ability. That is, make your
estimate, then see how near right it is by measuring. Learn to know how
an inch, a foot, a yard look. Then work with longer
