brates of upper Uinta age. Carnegie Museum parties have in the past 

 obtained a variety of the smaller mammals from beds at this locality. 

 Our party was no less successful, and was particularly fortunate in 

 opening a quarry for remains of small deerlike animals known as 

 leptotragulids and homacodonts. Several weeks were spent in work- 

 ing the quarry, a job which was difficult, not so much in the amount 

 of rock removed as in the care required in taking up delicate speci- 

 mens from a well-indurated matrix. 



The principal handicap encountered in working Myton pocket, and 

 other Uinta Basin localities, was the remoteness of palatable water. 

 Most residents in the vicinity of Myton drink water taken from the 

 Duchesne River, after allowing it to settle, but it was so cloudy and 

 distinctly alkaline that we preferred to haul ours from well supplies 

 in the towns of Roosevelt and Fort Duchesne. 



After 5 weeks at Myton pocket we visited several localities at more 

 easterly points in the basin and made collections from a lower horizon 

 known as Uinta B. Highly important for this early fauna is the 

 locality known to paleontologists as "White River pocket," a small 

 area of badlands near the junction of the Green and White Rivers 

 and not far from the Ouray trading post. Of particular interest from 

 this locality is the relatively rare Epihippus, a later stage in horse 

 development during Eocene time. At least two skeletal portions and a 

 few isolated jaws in our collection are believed from brief and 

 unsatisfactory field identification to represent this early horse. 



During our stay in the Uinta Basin we had the occasional and 

 enjoyable company of Dr. John Clark and his graduate student assis- 

 tant from the University of Colorado. Since their stratigraphic 

 studies were carried on in the eastern part of the basin it was possible 

 for us to join camps for a short time during our stay in Kennedy's 

 Hole. The latter locality proved somewhat less productive of paleon- 

 tological materials than we had anticipated, although we were much 

 pleased at finding a large crocodile skull and jaws. Here, and in 

 Coyote Basin to the south, the fossils are found principally in the 

 heavier sandstone lenses and one notes a greater proportion of 

 titanothere and rhinoceros remains. 



On August 20 we broke camp in the Uinta Basin and hauled the 

 bulk of our collection to Price, where it was boxed and shipped, and 

 on August 23 proceeded to southwestern Utah to investigate a lava 

 cave near Hurricane, reported to contain numerous animal remains. 

 These proved to be of no great antiquity. The field season was 

 terminated at St. George on August 25.
