ANIMAL PARASITES.
Efforts Being Made by the Gov

Millions of Dollars Lost Each Year
Through the Depredations of Insect
Pests-Sources Of Destruc-

the trichine of pork, which caused the
American hog to be shut out of Europe
so long are from rats, has given new
impetus to the pursuit OF n line OF in

the attention of the United states gov
eruruent. SAYS Washington corrSspon-
dent of the New York sun. DIR. Leuck-
hart, the great LeipSlc professor VINO
made the discovery, asccrtalned by the
dissection of rats that forty per cent OF
them were infected 10y trichlnn. halS

Human beings in their turn eat inc

fatal results frequently The disease Is
recIloned the most deadly known, mas
much as it kills in sixty per cent OF All
cases. Among the animals attacked by

bits. although how they get the PaTii-

The department Of agriculture Is at
present giving earnest attention 70 Inc
of finding out methods for fighting
against some of them which cause q
loss of many millions Of dollars yearly
IN farmers. II has made big discovery
recently in relation to the fatal disease
Of cattlc called Texas fever, which
is caused by minute animal
called a protozoon, that feeds on
the red corpuscles in the blood
and destroys them. Recent develop
rnauts of knowledge reveal the protozoa
rs producers of morbid complaints. II
has been asccrtaiuCd that the cause OF
malaria is Il protoZoon which leeds on
the blood cOrpuScleS, and another MI
crosopic foe of like description l. respon-
siblc for certain forms of dyscntcry.
Undoubtedly many disorders not now
understood will eventually be referred
to q similar origin.
The department is trying 70 discover
means for com mbating another parasite
