active means of spreading this disease. It is claimed that there 
are in this country annually over 200,000 cases of typhoid, about 
one-eighth of these cases resulting fatally. 
Not only is this insect 
a menace to children and 
adults in this connection, 
but is also a disseminator 
of various other deadly 
diseases, such as cholera 
(the cholera germ as well 
as the typhoid germ hav- 
ing been found in fly- 
specks), tuberculosis and 
numerous other danger- 
ous maladies. This filthy 
insect, then, is now known 
to be a serious menace to 
the health of human 
beings, and an active cam-

special danger of its pres- 
ence in a house lies in the 
Afiee Metcalf North Caroling Dept. of Agri. fact that in addition to 
cuNeure- the germs being able to 
pass through the aliment- 
ary canal and still retain their vitality, it can carry upon its feet and 
upon the hairs of its body thousands of germs which, introduced into 
the intestinal tract of man, may cause typhoid and other intestinal 
diseases, as well as consumption, and further be a cause of tnocu- 
lating wounds or abrasions upon the skin. It will therefore, be seen 
that the house fly may be the means of transporting disease quite a 
distance, and may possibly be the cause of an epidemic suiddenly ap- 
pearing in a locality for which no reason can be assigned. 
The following quotation from a leading entomologist, while 
not pleasant, is certainly suggestive, and deserves a place in any 
article on the house fly. 
“In the course of a few moments a single fly might crawl over excre- 
ment, sip from a glass of milk or water, and merrily chase across a dish of 
mashed potatoes and other human food. It may visit a dead and decaying 
animal, or sport about the mouth of a reeking sewer, and in the next five
