364 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



the Red Kiver until within a few miles of that stream, where it joins 

 the Cheyenne. The stream has cut for itself only a narrow, shallow 

 valley, and winds leisurely along through the level country with almost 

 an imi)erceptible current. At the place examined the stream is about 

 20 feet wide and 2.^ or 3 feet deep. The bed is of mud, with but little 

 sand or gravel, covered in many places with a thick growth of weeds, 

 grasses, and rushes. Two species of ditch-weed are common. The 

 banks are almost devoid of vegetation; an occasional willow or box- 

 elder is all that can be found. The stream was thorouglily seined at 

 the railroad bridge, but fish life was not abundant. Crawfish, leeches, 

 small crustaceans, water-snails, and clams were all well represented. 

 A very large species of Planorhis was particularly abundant. The 

 water was warm, 78°. 



Buffalo River, Haicley, Mmn., August 1. — This is a small stream about 

 50 miles long, rising in the White Earth Indian Reservation, Minn. It 

 flows southwesterly for about half its length, and then turning toward 

 the northwest joins the Eed River of the North at Georgetown. Haw- 

 ley is about 25 miles from the mouth of the stream. At this point the 

 stream is 20 feet wide and 2 feet in average depth. The water is clear 

 and the current rapid. The bed is of sand and small gravel, and almost 

 devoid of vegetation. The low banks are lined with small timber and 

 underbrush. The stream is well stocked with fish, but is obstructed 

 by several dams which prevent the running of the fish. The stream 

 contained rock bass, pickerel, catfish, minnows, and darters. A great 

 many clams were seen, and in several places the bed of the stream was 

 almost covered with these aniimals. Crawfish were rare. Temperature 

 of the water, 70.5°. 



Ooose River, HiUshoro, N.J)ak., August 4. — Temperature of the water, 

 70°; of the air, 73°. This is one of the small Avestern tributaries of the 

 Eed River of the North, rising in the elevation between Devil Lake 

 and the Red River. The course is southeast to its junction with the 

 Red, 12 miles from where it was examined. This stream has eroded 

 a very deep, w ide valley and the water flows at the rate of 4 miles per 

 hour. The stream averages 20 feet in width, but has a flood-plain 

 nearly half a mile wide. The depth varies from 2 to 5 feet, and the 

 water is cloudy. Algo6, water weeds, and grass grow in the stream at 

 the ripples. The banks and flood-i)lain are covered with trees which 

 form a forest of maple, box-elder, and willow. These trees have fallen 

 into the river until the channel is pretty well filled with brush and logs. 

 The stream has evidently cut through the lake dei)Osit and drift, since 

 the banks and bed, in places, are formed of a tough blue clay and at 

 intervals fragments of slate have accumulated. 



The stream was a difiicult one in which to make collections, but 

 Gatostomus teres, Lucius lucius, Moxostoma macrolepidotum duquesnii, 

 and a few other varieties were common. Many of the fishes, especially 

 of the genus Notropis, were profusely covered with immature parasitic
