WOULD DESTROY RODENT
PESTS BY INNOCULATrON

The following clipping from the
Kansas City star, submitted by a
subscriber. Is interesting to people OF
this county, treating of a new meth
Fod devised to destroy rodents thru
inpoculation Of q poison and thereby
carried from one to another:
ITS taps for rats and mice! For
science has outstripped the endea yors
Of all pipers, be they of Hamelin or
Kankakee, pied or otherwise.
"Bacteriologists in the Alexander
Laboratories in Kansas City are pro-
ducing = virus containing . germ
similar to the germ OF typhoid which,
attacks human beings. This germ,
will kill all rodents, but is harmless
to other forms of life,
Government statisticians have
told us that rats destroy 365 millio;,
dollars in property annually; that
one pair Of rats can have nine mil
lion offspring in seven years; that
rats spread disease and cause fires.
In 1909, DR.. Danysx, director of
the laboratory of NEUROLOGY at the
Pasteur Institute In Paris, discover
ed the virus now being developed
successfully in the Alexander labo-
ratories.
Dr. z. h. Alexander, president OF
the Alexander laboratories, says the
discovery of a method of producing
the Danysz virus and maintaining fts
virulency. will make Kansas City a
center for the production of the new
rat killer.
Production has been limited to
France and distribution has not been
general in this country. The French
psychologists, because of the eco-
nomic value, have been secretive. In
production, an ordinary gray rat.
such as infests barns and warehouses
is allowed to eat food moistened with
the viru. In about twenty-four hours
the rat begins to have a high tenn
perature. In six days he is dead.
The disease is found in The spleen
and heart.
