 3 or 4 miles below camp F, and very few dead or fragmenits of shells 

 Avere found. About 1 mile above Mount Hersey a few shells were

 scarce; green mugget, red mugget, grass mucket, Lampsilis liga- 

 mentinus, scarce; L. hreviculus hrittsi, scarce. 



None was found on an extensive sand and gravel bar at this point. 

 The bed of the river is very rocky with quite extensive shoals both 

 above and below Mount Hersey. A small bed was observed near the 

 mouth of Cave Creek, its presence being made known by old shells 

 and fragments on the gravel bars. No live mussels were seen, but a 

 few were observed by one of the rodmen. 



Station 8. — July 28. Above Wolem. A small mussel bed was ob- 

 served about 1 mile below camp G. A much larger bed is located 

 just above Wolem. Many mussels were seen here in the deeper 

 water, and many had been recently opened by pearl hunters. This 

 bed was at least three-quarters of a mile long, being much larger 

 than any previously observed.
