protection of the well from surface drainage, by seeing that the surface
wash is not allowed to drain toward it and that it is protected by a tight
covering from the entrance of its own waste water. If good water cannot be
secured in any of these ways, the water must be purified. It has been said
that what we desire in water supply is innocence and not repentance; but
if you cannot get pristine innocence, you can, at least, secure works meet
for repentance and make the water safe, by filtering through either a
Pasteur or a Berkefeld filter--either of those filters will take out
bacteria, while no other filters that I know of will or by various
chemical disinfectants, not any of them very satisfactory--or, best of
all, by boiling, which will surely destroy all disease germs."

Indians had a way of purifying water from a pond or swamp by digging a
hole about one foot across and down about six inches below the water
level, a few feet from the pond. After it had filled with water, they
bailed it out quickly, repeating the bailing process about three times.
After the third bailing the hole would fill with filtered water. Try it.

Drinking Cups

Insist upon the boys bringing to camp a supply of inexpensive paper cups
or collapsible pocket drinking cups. Filthy and dangerous diseases are not
infrequently transmitted by the use of a common drinking cup.

Paper Drinking Cup.

Take a piece of clean paper about 6 inches square and fold it on the
dotted lines, as shown in Figure 1, so as to make a triangle. Do not use
paper having anything printed on it, as there is danger of poison from the
ink. The other folds are made in the dotted lines, as shown in Figure 2.
