the Aikausas Eiver. It is about 2 rods wide and 2 to 4 feet deep. The temperature 
is about 73°. Its bottom is gravelly, rarely sandy, with some deep holes and with few 
water plants. Fishes are not plenty. Most were caught at the bridge, midway be- 
tween the lakes and the Arkansas Eiver, and about miles from either. The creek 
contains trout, suckers, and RMnichtliys, marked Gr in the list. 
5. Arkansas River at Canon City. — At Canon City, at the foot of its great canon, 
the river is somewhat turbid and has a temperature of 70°. The stream is rather 
swift, with gravelly bottom and no weeds. The bottom is muddy in places, doubtless 
from the placer mining above. The canon marks the lower limit of the trout and the 
upper limit of the fishes of the jilains. Fishes are scarce in the river here, the four 
species seen being marked A in the list. 
6. Pond at Canon City . — Opposite Canon City is a small clear pond fed by sweep- 
ings from irrigating ditches, full of chara and other weeds. The water is warm, tem- 
perature 80°, and the pond and its small outlet is full of small fishes. The pond is 2 
rods long and 3 feet deep. The species taken here are marked C in the list below. 
7. Crape Creek above Caiion City. — Grape Creek is a small but long stream, rising 
in the Wet Mountain range, flowing in a narrow valley with precipitous walls, and 
emptying into the Arkansas from the south 2 miles above Canon City. The water is 
clear and cold, temperature 66°. The current is swift and the bottom of sand and 
gravel without weeds. It is about 6 feet wide, 12 inches deep, with a few pools. In 
the deep places is Rhinichthys dulcis. No other fishes were seen. It is said that 
trout occur some 18 miles up the creek, but not in abundance. Four-Mile Creek, be- 
low the town, is a similar stream. Some seventeen years ago, we are informed, this 
stream was fnll of trout, but in a dry summer it was reduced to a series of pools. The 
settlers gathered the trout then with dip-nets and the herons took all that were left. 
Since then no trout have been seen there. 
8. Arkansas River at Pueblo. — At Pueblo the river becomes warm, 80°, and dark 
gray in color. It is about 4 rods wide and 2 to 5 feet deej), with swift current. The 
bottom is gravelly, with stretches of gray mud. There are no deep pools or quiet 
reaches and no water plants. Fishes are plentiful, especially in the shoals. Collec- 
tions were made at Good Night Eanch, 5 miles west of Pueblo, above and below Mr. 
Bell’s residence. Close along the river the banks are green, but the region about is a 
hot, barren mesa, with scanty vegetation. Fishes from Pueblo are marked P in the 
list which follows. 
9. Fountain Creek at Pueblo. — Fountain Creek is a long stream rising in the mount- 
ain brooks about Pike’s Peak. It is formed at Manitou Springs by the union of two 
streams, the Euxton, rising on Pike’s Peak, and the Font-qui-Bouille, which rises in 
Ute Pass. The Euxton, a mountain torrent, is without fish, but into a tributary pond 
eastern trout have been introduced. The Fout-qui-Bouille, also without fish, has in its 
course both iron springs and water- falls. The iron springs give the water a red tinge. 
The waters of Fountain Creek are chiefly consumed by the irrigating ditches. At 
Pueblo it is a clear shallow stream, 6 feet wide by 4 inches deep, in a wide sandy bed. 
Temperature, 70°. Species from Fountain Creek are marked F. 
10. Arka^isas River at Wichita, Kans.— A collection comprising 27 species was 
made for us at Witchita by Mr. Sherman Davis. The river at Wichita is broad and 
muddy, with soft bottom, and the species obtained are mostly those of the muddy or 
sandy prairie streams of Kansas.
