FISHES OF SOUTHWESTERN MINNESOTA. 615 



in the spring, and that in the spring of L894 very few had been seen. 



None arc ever taken with hook and line. Careful seining tailed to 

 capture the young of either. 



A number of citizens of Worthington reported that in 1893 the 

 buffaloes tried to pass from one Okabena Lake into tin- other, and 

 that immense numbers were speared, many of them weighing 40 pounds 

 apiece. It is reported that the farmers came there ami hauled away 

 wagouloads of these fishes and dressed and dried them for winter use. 

 Daring the last few years very tew have been seen. .Many dead sink- 

 ers were reported along the shores of West Okabena Lake in thespriug 



of 1894, when the ice melted. Similar reports come !'r Round Lake, 



but at the time it was visited by the writer (spring of 1894 i the buffalo 

 had not been seen, and careful seining failed to secure specimens of 

 either suckers or buffalo. 



What information the writer has been aide to obtain concerning t hese 

 tish is very unsatisfactory. Their sadden appearance and their as 

 sudden disappearance render it difficult to make observations on them, 

 and the fact that they are never taken during the remainder of the year 

 increases the difficulty of obtaining accurate information concerning 

 them.
