laboratory of the Canal Zone that the disease is 
transmitted by flies in many instances, and that 
mules are also liable to the infection, mules also

and signs a receipt in full; and that the Depart- 
ment’s portion of the valuation does not exceed 
one hundred dollars. In view of the curative and 
preventive results produced in the work of the 
hygienic laboratory of the Canal Zone, it is not 
impossible, should the results be proven reliable, 
that the killing of such animals may be discon- 
tinued.
