American house flies this country has
been hopelessly outclassed. according

by the United States public health
service.
In view OF the house fy's record as
a dangerous enemy TO mankind in his
ability to transmit disease, IL was
agreed between scientists OF both
countries that there should be a series
of fights TO determine Just how far
the fly can carry his bacilus-coyered
