142 OWLS AND MARMOTS.

 at the expense of the prairie dogs, who serve them as 

 builders, and too often, it is said, for food. They prey 

 upon the industrious little creatures who provide them 

 with a dwelling-place. 



We were desirous of obtaining a confirmation of this

 them ! 



So far as relates to the rattlesnake, he seems to play a
