across the cliaime], almost to the surface of the water. The stream 

 was fished at Powers Ford, 3 miles north of the town, where the mud in 

 the bed of the stream gave place to a bed of gravel and the banks Avere 

 of sufficient slope to permit the landing of the seine. Temperature of 

 the water, 81°. 



Jamestoivn, K. DaJc., August 28. — The James Eiver was fished the sec- 

 ond time at Jamestown, about 55 miles northeast of La Moure. The 

 character of the country is similar lo that around La Moure. The hills, 

 however, are farther from the river. The soil contains a great many 

 more bowlders, but these are mostly small. It is also filled with banks 

 of coarse, water- worn gravel, containing clay and iron nodules. The 

 river at this point is about 18 to 20 feet wide and from 2 to 3 feet deep. 

 The stream is obstructed here b3^ a high dam built for power purposes. 

 The collecting was done below the dam, where the stream is composed 

 of a series of ripples, and the water runs rapidly over a clean gravelly 

 bed. The banks of the stream are composed of drift, covered with 

 vegetation that grows to the water's edge. The banks are also lined 

 with a natural growth of small timber, such as box-elder, maple, elm, 

 and three varieties of willow. There is a scant water vegetation where 

 the stream was examined, Avhich covers the large stones of the bottom. 

 A few crawfish were found, and also a few water-snails. The stream 

 swarmed with small fishes; Rhinicliiliys was taken by hundreds; Pime- 

 phales, Notropis, and Etlieostoma were also well represented. The stream 

 at this place is well adapted, to darters and dace, being quite clear 

 and cool. The temperature of the water, 60°, would indicate consider- 

 able spring water, though no springs were observed. 



Pipestem Greeic, Jamestoiim, N. Bale., Juhj 27. — This is a small western 

 tributary of the James River, flowing nearly parallel with, and between, 

 the same two ranges of hills. It is about 50 miles in length, narrow 

 and deep. It is a poor stream in which to make collections, since no 

 ripples were to be found. The water is clear; the temperature 62°.
