264 BULLETIN OF THE UNITED STATES FISH COMMISSI 01 . . 
1. Clear Creek , near Wildie, 1 mile west of the railroad station, which is 10 
miles northwest of Livingston, on the Kentucky Central Railroad; temperature of the 
water, 72° F. Clear Creek is tributary to Round Stone, and this again to the Rock- 
castle River. Round Stone receives Clear, Brush, and Crooked creeks above the 
u Sinks,” and, after flowing under ground for a distance of 4 miles, joins the Rock- 
castle River at the u Boils,” near Livingston. Clear Creek is a smooth, open stream, 
offering a good opportunity for collecting. It is not more than 20 miles long, and 
throughout its lower course is about 10 yards wide. The crooked valley through 
which it flows is narrow and low, the immediate banks being but a few feet above 
the water, so that they are easily overflowed. The water is quite clear. The ripples 
are short and shallow, flowing over piles of gravel, between which the depth is nearly 
uniform (about 3 feet) and the bottom bed of rock. Little or no vegetation was 
found growing in the bed of the creek; the banks were lined with willows, sycamores, 
and cottonwoods. The stream contains an abundance of fishes, such as bass, suckers, 
and minnows, Campostoma anomalum being the most abundant. Notropis megalops 
and Notropis umbratilis were also very abundant. 
2. Little Rockcastle River , 6 miles northeast of Livingston, August 12 ; water tem- 
perature, 62° F. Little Rockcastle River is a small, shallow, but comparatively wide 
stream, tributary to Rockcastle River; a number of coal shafts open into its valley. 
The bed of the stream is covered in places with the slack coal from the mines, to a 
depth of 1 to 3 feet, and this in turn is sometimes covered with sand, through which 
the collector makes his way with difficulty. The water has a decided bluish tinge, 
caused probably by the copperas (FeS0 4 ) from the mines. The stream was seined in 
several places, but not a specimen of fish was taken or seen, the stream seeming to be 
devoid of both animal and vegetable life, due probably to the poisonous salts of iron. 
3. Rockcastle River , one-half mile above the mouth of the Little Rockcastle River, 
August 12 ; water temperature, 64° F. The Rockcastle River rises in the mountains 
of Jackson County, flows southwesterly 50 or more miles to the Cumberland, and is 
the largest northern tributary of that river coming from the mountains. It has all 
the characteristics of a mountain stream, being swift, rocky, and in places deep. The 
hills on either side are composed principally of sandstone, which, during heavy rains, 
split off in large land-slides and fall into the water. At this station the river is 25 or 
30 yards wide, and rushes over a very rocky ripple. The water was from 2 to 3 feet 
deep, being slightly swollen by recent rains. Rear the shore were a few small sand- 
banks, on which grew some wild grasses and mints. No unios or crayfishes were 
taken, and but few fishes. The stream is a favorite resort for the angler, black bass 
being taken in large numbers. 
4. Rockcastle River, 2 miles from Livingston, August 13; water temperature, 63° F. 
The character of the stream was much the same as at the last station above described. 
It was not, however, a good place for collecting. More soft-rayed fishes were taken 
here than at the former place, suckers ( Moxostoma duquesnei) being comparatively 
plentiful. 
5. Cumberland River at Barbourville, August 14; water temperature, 62° F. Col- 
lections were made just south of the town, both above and below the mill. The 
stream at this point, 80 miles above the falls, is more than a hundred yards wide, 
rapid and rocky. The deeper places have a smooth rock bottom, with a greater or less
