Some day soon high.bro sclent-

volumes which the irreverent will be
likely to call "The Bug House In

He will start by showing that mos
Iuitoes were responsible for the
downfall OF the Roman empire; that
not until the strong arms OF the Ro-
man cohorts were filled with the
germs Of malaria and their proud spir

did they yield 10 this invasion of the
barbarlans fIom the north. And, OF
course, the only way malaria can be
communicated Is By the bite Of a mos

man who has malaria. Tho Difficult.

The second volume will blame an
other mosquito. his Latin name is
stegomyia--for the failure Of the
French to build the Panama canal.
Stegomyia ls solely responsible for
the prevalence OF yellow fever. and

which live most of the time on the
bodies OF rats and other rodents
The "Swat That Fly" campaigns at

that the fly Is dangerous beast. II
the campaigns are undertaken in May
