State of Connecticut. The work was handled by the Hartsville, Mass., 
station, which also propagated its normal quota of trout, many of 
which were of large size. 
The St. Johnsbury, Vt., station achieved unusually good results in 
rearing landlocked salmon fingerlings. W. P. A. assistance permitted 
the renewing of foundations of the hatchery building, as well as plaster- 
ing the interior of the building, painting exteriors, and improvements 
to ponds and grounds. The work at this station was closely coordi- 
nated with that at the York Pond, N. H., station. 
COMBINATION TROUT AND PONDFISH STATIONS 
In view of the overlapping of the range of cold-water and warm- 
water species, the desirability of propagating both at the same hatchery 
is self-evident. In practice, combination hatcheries have generally 
proved to be most efficient with one or the other of these two types. 
Natural conditions have determined which group could be produced 
most efficiently. Stations in this category were nevertheless of great 
importance in maintaining a balanced distribution program in 1937. 
The Neosho, Mo., station has been conducting a number of inter- 
esting experiments in the development of a more economical and 
satisfactory food for rainbow trout. Earlier experiments indicated 
that an excessive proportion of dry foods affected the growth and the 
egg production. Production of fingerlings for distribution showed a 
slight improvement over last year but the egg collections were some- 
what less. Interesting results were achieved in the artificial feeding 
of bass fingerlings, utilizing the same food as is employed with rainbow 
trout. Bream were also reared by the same means. The fish were 
unusually free from disease. 
At the Bourbon, Mo., substation, operated on a cooperative basis, 
rainbow egg collections were less than for several years past, due to 
a curtailment in the number of breeders carried. 
Aside from a normal production of trout at the Erwin, Tenn., 
station, a yield of over 500,000 bass was unusually favorable. 
The Flintville, Tenn., station continued to experience difficulty in 
the propagation of pondfish, due to seepage of water in the rearing 
ponds. The station discontinued the maintenance of brood stock for 
the collection of rainbow trout eggs, the requirements for this species 
being taken care of by the shipment of eggs from other sources. A 
garage building was constructed during the year. 
At the Lake Mills, Wis. station, W. P. A. construction has continued 
throughout the year, resulting in the completion of one large pond and 
five smaller ponds, together with other general improvements. The 
production of bass at this point exceeded that for the previous year. 
The Lamar, Pa., station is in an incomplete status and is utilized 
only for the rearing of trout which are transferred in the fry stage from 
other stations. Over 200,000 fingerlings of three species were dis- 
tributed. At the close of the year arrangements were being made for 
development of a C. C. C. construction program, involving erection 
of a hatchery building and the construction of bass ponds. This 
labor was also utilized during the year for the construction of eight 
trout-rearing ponds, landscaping, road building and general im- 
provements. 
The output of the Manchester, Iowa, station fell below the level of 
the previous year but the production of 1,500,000 rainbow trout eggs
