S2 Expedition to the 



A little before noon, Ave crossed a small stream, which 

 was called Castle Rock creek, from a remarkable pile of 

 naked rocks, and halted for dinner on the bank of the river. 



in the morning, Mr. Peale and two hunters, had taken a 

 different route from the remainder of the party, hoping to 

 meet with game. They arrived at a small grove of timber, 

 where it was thought deer might be found. They therefore 

 left their horses in care of one of the hunters, and entered 

 the wood on foot. The man had been left alone but a short 

 time, when he discovered a large grizzly bear approaching 

 rapidly towards him, and without staying to make himself 

 acquainted with the intentions of the animal, mounted his 

 horse and fled. 



The grizzly bear* is widely distinct from any known spe- 



* Ursus horribilisy Ord. JF/ air Iodj, sliort on the front, very short be-

 longer on the shoulders, throat, and behind the thighs, and beneath the 

 bell3', and paler on the snout; ears short, rounded; yVoni arquated, the line 

 of the profile continued upon the snout, without any indentation between 

 the eyes; eyes very small, destitute of any remarkable supplemental lid; 

 iris burnt sciena, or light reddish brown; muffle of the nostrils black, the 

 sinus very distinct and profound; lips, particularly the superior one, an- 

 t?riorly extensile, with a few more rigid hairs or bristles; tail very short, 

 concealed by the hair. The hair gradually diminishes in length upon the 

 leg, but the upper part of the foot is still amply furnished. Teeth, inci- 

 sores 6, the lateral one with a tubercle on the exterior side ; canines large, 

 robust, prominent; a single false molar behind the canine, remaining mo- 

 lares four, of which the anterior one is very small, that of the upper jaw 

 particularly, that of the lower jaw, resembling the second false molar of 

 the common dog. 



Anterior feet, claws elongated, slender; fingers with five suboval naked 

 tubercles, separated from the palm, each other, and from the base of the 

 claws by dense hair; palm on the anterior half naked, transversely oval; 

 base of the palm with a rounded naked tubercle, surrounded by the hair. 



Posterior feet, with the sole naked, the nails moderate, more arquated, 

 and shorter than the anterior ones. 



The nails do not in the least diminish in width at the tip, but they be- 

 come smaller towards that part, only by diminishing from beneath. 



" Testicles suspended in separate pouches, at the distance of from two 

 to four inches from each other." — Lewis <^ Clark?

 gradations, fiom a dark brown to a pale fulvous, and a grayish.
