carriers of disease may never be
born.

If there is one sweet morsel above another for this fly pest it is
tubercular sputum or feces, and from these feasts they go directly to
walk over baby's hands, crawl over his cheek, and wash their feet in
his milk. Proper screenage will prevent such contamination of food,
such opportunities for carrying disease.

Sunshine, hot water, soap, and fresh air, are the best ordinary
every-day disinfectants. It is possible so to conduct the treatment of
a contagious or infectious disease that no other member of the family
may contract it. A few simple but very important hints are:

1. Door knobs are one of the very greatest avenues of
contagion--disinfect them.

2. Cleanse the hands both before and after attending to the sick;
first, scrub with stiff brush, soap and water, then dip in alcohol.

3. An epidemic of sore eyes may be stopped by absolute "hand
disinfection" and using separate towels.

4. Do not go visiting when you have a "common cold."

5. Kissing is one of the best ways of spreading many diseases.

6. In cases of contagious and infectious diseases completely cover all
excretions from the body with lime.

7. Country homes would be as healthy as city homes if the privies and
stables were screened.

8. In the country, the well water should be boiled; one infected well
may be the cause of the death of a score of beautiful children.

INCUBATION PERIODS

The incubation period of scarlet fever is from one to seven days.

Measles, ten to twenty days.
Whooping cough, from one to two weeks.
Chicken-pox, fourteen to sixteen days.
German measles, seven to twenty-one days.
Diphtheria, any time from one to twelve days.
Mumps, from one week to three weeks.

Of all the diseases, measles and chicken-pox are probably the most
contagious. In scarlet fever and diphtheria, close contact is
necessary for exposure, while whooping cough can actually be
contracted in the open air, young babies being particularly
susceptible.

TYPHOID FEVER

Typhoid fever is a disease of the small intestine. Typhoid germs
accumulate in the little lymph nodes of the small intestines and that
is the reason why we often have so many hemorrhages from the
bowel--actual ulcerations take place--and if an ulcer is situated in
the neighborhood of a blood vessel hemorrhage may result.

Typhoid fever begins rather insidiously with a slight debility and
loss of appetite, but if a temperat
