 the skull and lower jaws. 



Leaving this locality the party returned to Clarendon, then 

 going west about twenty-five miles to the head of Mulberry 

 Canon turned southeast about three miles and established a 

 camp at the top of the bluffs a little to the west of the mouth 

 of the canon. It was at this locality that Cope and Cummins 

 reported a new geological horizon which Cummins called the 

 'Goodnight Beds' and which Cope considered the same as the 

 Paloduro beds, placing them, in time, between the Loup Fork 

 (Miocene) and Blanco beds which are true Pliocene. 



The party remained several days in this locality and the 

 writer explored both sides of the canon for its entire length, 

 failing to find any evidences of a break in the stratigraphie 

 continuity of the deposits on opposite sides of the canon, as 

 reported by Cummins. 



From Mulberry Canon the party traveled southeast, crossing 

 the South Fork of Red River near the mouth of Mulberry 

 Creek, continuing south to a point nearly due east of Silverton, 

 the county-seat of Swisher County, turned west and ascended 

 the steep and rugged escarpment to the top of the Staked 

 Plains. Continuing west, passing the head of Rock Creek, a 

 third camp was established at the head of Tule Canon. 



The deposits here and extending east to and beyond Rock 

 Creek on the south side of the canon, and for some distance 

 along the north side of the cailon as well, are of Pleistocene 

 formation. At the head of Tule Canon was found a specimen 

 of Elephas imperator (No. 10598, American Museum Collec- 

 tion), consisting of a complete fore limb, part of the fore foot, 

 the lower jaw and upper teeth, besides a few vertebrae and 

 ribs. 



Returning to the head of Rock Creek, seven miles to the 

 east of the Tule Canon camp, the party established a fourth 

 camp. At this locality was made the splendid find of fossil 

 horse skeletons {Equus scotti) already d'escribed by the writer. ' 



This practically ended the season's work, the party return- 

 ing to Clarendon by the way of Canyon City at the head of
