fiat distributions from the Grand Lake substation consisted of 
880 brook-trout fry, 115,000 eyed eggs of the landlocked salmon, 
sh ‘000 landlocked-salmon fry, and 79, 100 landlocked-salmon finger- 
lings, with approximately 74,000 fingerlings of that species on hand | 
at the end of the year. 
NASHUA (N. H.) STATION. 
[WaLpo F. HuBBarD, Superintendent. ] 
The work at this station was concerned with the brook and rainbow 
trouts, pike perch, and smallmouth black bass. A few brook-trout 
eges were obtained from brood fish at the station, but most of the 
eggs of this species were acquired by purchase. The rainbow eggs, 
with the exception of 16,638 taken from fish in the hatchery ponds, 
were transferred from the Wytheville (Va.) station, and the pike- 
perch operations consisted in the incubation of 2,000,000 eyed eggs 
shipped from Swanton, Vt. During the spawning season of the 
smallmouth black bass in Lake Sunapee, extending from June 2 to 
June 17, collections of fry of that species to the number of 31 5700 
were made and shipped to applicants. The work with the various 
species was conducted without unusual incident, and the output of 
fish for distribution is shown in the table on page 12. 
ST. JOHNSBURY (VT.) STATION. 
[A. H. DINSMORE, Superintendent. ] 
From this station as a center the usual field stations for the collec- 
tion of brook-trout eggs were operated at Lake Mitchell and Darling 
Pond. Largely because of climatic conditions, the results of the 
work at both points were rather unsatisfactory. The egg collec- 
tions amounted to 214,148 and 411,777, respectively, all ‘of which 
were of the usual high quality. 
During the summer of 1920 an investigation was made of the 
fish-cultural possibilities existing at points on the Big Margalloway 
and Little Margalloway Rivers and Parmacheence Lake, im northern 
Maine. As the field gave promise of satisfactory returns, a tentative 
plan was formulated “for undertaking work in cooperation with the 
Northern Oxford Guides Association. The first eggs were taken 
October 13, and the collections, which extended to October 27, agere- 
gated 300,000. As the main objects of the work were to build up the 
supply of trout in the local waters and to encourage the local or- 
ganization in their fish-cultural activities, the bureau claimed only 
50,000 of the eggs secured. The others were successfully incubated 
in the log hatchery put up by the association, and the resulting fry 
were planted, with but slight loss, in local waters. While the ‘work 
was not particularly successful from a fish-cultural standpoint, the 
information gained will be useful in connection with any future work 
that may be ‘attempted i in that field. 
At Lake Dunmore, Vt., a new field station was established for the 
collection of lake-trout egos and was operated jointly by Federal 
and State employees. Egos to the number of 130,000 were collected 
and sent to the Holden hatchery, another subsidiary of the St. Johns- 
bury station, to be eyed. After reaching the eyed stage half of 
them were turned over to the State fisheries authorities.
