FISHES AND FISHING IN SUNAPEE LAKE. 15 



of Sunapee Lake six-tenths of a mile to the westward, at an altitude 

 of 1,113 feet, thus giving its outlet, which leaves Spectacle Pond from 

 a deep cove at the eastern side of the apex of the triangle, flowing 

 southwest and west, a fall of only 22 feet, passing through a practi- 

 cally level country 



Mud Pond is practically a small diverticulum of Spectacle Pond. 

 Sucker Brook entering Fishers Bay of Sunapee Lake is practically 

 a bog brook throughout its extent. 



The brook at Siuiapee Harbor is also a small brook flowing over a 

 rocky bed, mostly through woodland, to a short dead water at the 

 lake. The brook is ascended by smelts in the spring, but on August 

 17, 1910, it was absolutely dry. 



Jobs Creek Brook is another inconsiderable rivulet flowing into 

 Jobs Creek, entirely dry in the dry season. 



Sugar River, the outlet of Sunapee Lake, leaves the lake at Sunapee 

 Harbor over a considerable descent formed by a natural steep ledge and 

 bowlder fall and a dam. For some distance below the mill and factory 

 it is a "rocked up" or walled raceway, the bottom of which is com- 

 posed of coarse gravel and blue clay. The water flows swiftly over a 

 steep descent for perhaps one-fourth of a mile or more from the lake ; 

 at the foot of this passage the stream expands into a shallow muddy 

 dead water about 40 feet wide, more or less, according to height of 

 water. Below this the river was not examined. On July 22 the 

 water was very low with no current below the race. Temperature, 

 77° on July 27. The water was dirty, warm, and sluggish. In 

 October the current was swift in the ''race" and full of fine debris of 

 various kinds. 



NATIVE FISHES. 



The fishes inhabiting Sunapee Lake and tributary waters prior to 

 the fish cultural introductions, which began in 1867, so far as records 

 thus far show, comprised an even dozen species. These are: Horn 

 pout (Ameiurus nebulosus); sucker (Catostomus commersonii) ; chub 

 (Semotilus lullaris) ; blackspot chub (Semotilus atromaculatus) ; redfin 

 (Notropis cornutus); black-nose dace (Rhinichthys atronasus); ''native 

 trout" (Salvelinus fontinalis); "white trout" (Salvelinus aureolus"'); 

 eel (Anguilla rostrata); pickerel (Esox reticulatus) ; sunfish or "pump- 

 kin seed" (Lepomis auritus ^) ; perch. (Percajlavescens). 



Of these, in the lake itself, only the horn pout, sucker, white trout, 

 and sunfish seem to be at all common. In the brooks the trout and 



a For reasons set forth in this paper in connection with this species, it is assumed that it is native to the 

 lake. 



b It is probable that another species (Lepomis gibbosus) occurs in some ponds connected with the lake, 

 and the writer has been informed that it has been found in the lake; but in his observations, covering two 

 seasons, he has seen none. There are published statements that the little fresh-water sculpin or " miller's 

 thumb " (probably Cottus gracilis) was once common. It appears to be extinct now, or if present it is so 

 scarce that none was observed in two seasons.
