FISHERIES, GAME AND FORESTS. 243 



1436. Common sunfish (pumpkin seed) {Eupomotis gibbosus Linnasus). — Fourteen, 

 all caught in the latter part of May and in June. They spawn in this region in June 

 and July. Many of these taken were immature. 



1438. Large-mouthed black bass (Microptcrus salmoides Lacepede). — One. 



1443. Yellow perch (Perca flavescens Mitchill). — Fourteen. It should be noted 

 that the spiny-rayed fishes were caught in greater numbers in the latter part of the 

 season, while the soft-rayed fishes (notably the suckers) were caught earlier. This 

 agrees with their general periods of spawning. 



[474a. Tessellated darter (Boleoscma nigrum olmsteadi Storer). — But two were 

 caught, although this darter is very common in the stream. They are so small that, 

 like many other fishes of the smallest sizes, they are able to go through the meshes of 

 the netting. 



2335. Star-gazer or miller's thumb (Cottus ictalops Rafinesque). — Only specimen 

 of this species was caught, although at times they are not very rare in the lake. 

 They spawn in the shallow water of the lake, in the latter part of April. 



Although this completes the list of fishes, mention should be made of the facts 

 ascertained concerning the habits of the Batrachian (Nectunis maculatus), mud puppy 

 or water dog. These serious enemies of our fishes go up stream to spawn in the latter 

 part of March and the early part of April. Their eggs were taken from the water on 

 April 16, and on June 16 two young necturi, each one and one fourth inches in 

 length, were taken from beneath the trap. 



Owing to the many washouts, it cannot be said that the weir this year was a 

 marked success, although it surely would have proven satisfactory during ordinary 

 seasons. 



In order to see what could be done with hand nets alone, the writer engaged 

 an assistant during the spring of 1899, and waded the stream every one or two days, 

 removing all lampreys possible. Over eighteen hundred were killed in this way, but as 

 we did not see all of those which were collected by the assistant, it was impossible 

 to make an accurate record of the proportions of the sexes represented.
