firming telegram from this office of even date, I quote below letter received 
from the State Department, dated May 6, 1914: 
“Referring to previous correspondence on the subject of the use of the 
d@’Herelle bacillus for the extermination of locusts, I have the honor to 
say that the Department has received a telegram from the American 
Minister at Bogota, dated the 2nd instant, in which he states that ex- 
haustive experiments for the extermination of the locust have recently 
been completed by the Colombian Central Commission, and that they proved 
that the d’Herelle bacillus was effective but the application of it was not 
practical. 
Mr. Thomson added that he was informed that experiments made in 
January in the Argentine Republic, under the supervision of d’Herelle 
himself, gave the same results and that the efforts now being made must 
look to the discovery of a practical method of disseminating the germ. Mr. 
Thomson further stated that he would forward reports just published by 
the Colombian Central Commission.”
