 weakness of its feet, between the fissures of rocks 

 which have been forced open either by the vio-

 rocks, forming a large oblique or winding passage 

 through which it flings out the earth, and from

this passage proceeds another hole (and some- 

 times there are two), pointing downwards, and 

 winding among the rocks, and in the bottom is 

 situated the nest, composed of soft herbs. The 

 principal food of this species, according to Dr. 

 Pallas, consists of the seeds of various species 

 of Astragalus or Milk-Vetch.
