spicuous compared with that of the trout or most other fishes. At this time it will 
occasionally take an artificial fly, as also sometimes on cloudy days, but the most suc- 
cessful method of angling for it- is that described above by Atkins. It may be caught 
in gill nets'* if set in deep water The writer has taken white-fish in August in gill 
nets set at the bottom, extending from a depth of 75 to 115 feet, and from rocky to soft 
muddy bottom. The white-fish were about midway of the net, but this is most likely 
due to the part being more favorably constructed. Gill nets should be tan-colored. 
This white-fish feeds upon small animals of various kinds and probably almost 
any kind. White-fish taken in First Debsconeag Lake August 12 and 24, 1901, con- 
tained large quantities of larva? of a species of dipterous or mosquito-like insect. 
The height of the spawning season seems to be about November 25 in the Fish 
River Lakes, where the fish run up the thoroughfares at night and descend before 
morning. They spawn in running water over gravel and where the water ranges 
from I to 3 feet deep. They also ascend streams for this purpose, but so far as

known do not spawn on shoals or shores of lakes. The nearest approach to shore 
spawning known to the writer is in First Debsconeag Lake, where they seek the lake 
(md of the shallow strait connecting the lake with Debsconeag Dead water. Atkins 
states that the fecundity of a 2-pound white-fish is 25,076 ova. In some Maine lakes 
this species attains a weight of 4 or 5 pounds, but the average is 1 to 2 pounds. 
It is not known to the writer that the young of this species has been observed, 
except the fry at fish-hatcheries, or where they are to be found after leaving their 
birthplace in the thoroughfares and streams, or at what age they leave these places. 
It is probable that when quite young they go to deep water, where having thus 
escaped their enemies of the streams they become the prey of the rapacious fishes of 
the lake. Young individuals ranging from 4.63 to 9.5 inches long were collected in 
the Allagash and St. Francis waters in October, 1901, with a drag seine, along the 
shores of the lake. The method employed was to bait the shore about dark with fish 
and ruffed-grouse entrails or with corn-meal mush, and in about an hour draw the 
seine over the baited ground, when these fish were taken, together with hornpout, 
This method is unlawful in Maine except by special permit from the commissioner of inland fishes and game.
