onia. We are beginning to find
that these last two groups will bear watching. Like camp-followers
elsewhere, they carry knives, and are not above using them on the
wounded after dark. In fact, they have a cheerful habit of taking a
hand in any disturbance that starts in their bailiwick, and usually on
the side against the body-cells.

Finally, while clearly realizing that the best defense is attack, and
that our chief reliance should be upon keeping ourselves in such
fighting trim that we can "eat 'em alive" at any time, there is no sense
in running easily avoidable risks, and we should keep away from
infection as far as possible. If a child comes to school heavy-eyed,
hoarse, and snuffling, the teacher should send him home at once. He will
only waste his time attempting to study in that trim, and may infect a
score of others. Moreover, it may be remarked, parenthetically, that
these are also symptoms of the beginning of measles, scarlet fever, and
diphtheria, and two-thirds of all cases of these would be sent home
before they could infect any one else if this procedure were the rule.

If your own child develops a cold, if mild, keep him playing
out-of-doors by himself; or if severe, keep him in bed, in a
well-ventilated room, for three or four days. He'll get better twice as
quick as if at school, and the rest of the household will escape.

When you wake with a stuffed head and aching bones, stay at home for a
few days if possible, out of regard for your customers, your
fellow-clerks, or your office force, as well as yourself. If one of your
employees comes to work shivering, give him three days' vacation on full
pay. If it runs through the force, you'll lose five times as much in
enforced sick-leaves, slowness, and mistakes. Above all, don't go to any
public gatherings,--to church, the theatre, or parties,--when you are
snuffling and coughing. You are not exactly a joy to your beholders,
even if you don't infect them. It is advisable, and well worth the
trifling trouble and expense, to fumigate thoroughly with formalin all
churches, theatres, and schoolrooms at least once a month. Reasonable
and public-spirited precautions of this sort are advisable, not only to
avoid colds themselves, which are disagreeable and dangerous enough, but
because mild infections of this sort are far the commonest single means
of making a breach in our body-ramparts through which more serious
diseases like consumption, pneumonia, and rheu
