Tlie United States Department of Agriculture estimates the 

 annual loss from injurious rodents throughout the United States 

 as $100,000,000.00. 



In Colorado we have over fourteen million acres infested with 

 prairie-dogs, and over one million acres infested with the Wyoming 

 ground-squirrel. These figures are estimates made from records 

 we have in the office of the State Entomologist. Roughly speaking, 

 these two rodents infest fifteen million acres of land in our State. 



If we figure the damage done to crops and forage at a con- 

 servative estimate of ten cents per acre, the annual loss is $1,500,- 

 000.00. This is not taking into consideration the loss from the 

 striped ground squirrels, kangaroo rats, pocket gophers, mice, 

 rats, etc. 



In our opinion the annual loss to the State from injurious ro- 

 dents is, at a very conservative estimate, $2,000,000.00.
