The Deficiency Bill carried $10,000 for experimental control of 
the spruce budworm in the Cody Canyon of the Shoshone National Forest. 
This is the east entrance to the Yellowstone National Park. A severe 
infestation of the spruce budworm has been progressing here for three 
or four years, and an attempt will be made to save the timber along 
the roadsides and around tourist camps by Spraying with lead arsenate. 
From an investigational standpoint it is hoped that this work will dem- 
onstrate whether or not this insect, which feeds more or less concealed 
in the opening buds, can be controlled by arsenicals, and will determine 
the best time for application and the proper dosages.
