fish earlier than usual which resulted in an increase of 38 percent over 

 the output for the previous fiscal year. The aid of the State fish and 

 game department was enlisted in distributing the fish. Throughout 

 the year improvements to the grounds, equipment, and buildings 

 were under way. The provision of additional pond space has been 

 continued and three new wells were drilled to add to the water supply. 

 An office building was completed and two small pump houses were 

 constructed. 



The Bozeman, Mont., station is headquarters for nnportant activ- 

 ities with auxiliaries located at Ennis and Miles City, Mont., where 

 pondfish are propagated, and at Glacier Parlv. Fish cultural work at 

 Bozeman ^^as conducted with gratifying success, and extensive im- 

 provements with funds derived from P. W. A. and C. W. A. sources 

 were provided. This consisted of rcorKlitioning of the hatchery, the 

 conversion of a stable into a duplex dwelling, improvements to the 

 donestic water supply, construction of rearing ponds, and the starting 

 of construction of an ice house and refrigerator roojn. The work in 

 the Madison Valley w as centered at Ennis, where a new hatchery was 

 placed in active operation at tlie beginning of the fiscal year. The 

 collection of Loch Leven trout eggs in this field amounting to 28,500,- 

 000 exceeded all previous records. The yield of pond fish at the Miles 

 City auxiliary station was fully adequate to meet requirements. 

 A change in policy was established by the practice of wintering the 

 adult brood stock in a small leased itike rather than attempting to 

 hold tliem in the larger Miles Citv ponds where previous experience 

 has shown a heavy mortality during the winter. The total yield of 

 fish from this source was over 316,000 wliich was below the record for 

 the previous year but the fish appeared to be of larger size. 



The (xlacier Park substation was operated as usual, incubating 

 eggs and rearino- fingerlings shi]-ped in from other hatcheries. Difli- 

 culty was experienced when the chlorinated water supply used by the 

 Park Hotel gained access to the iiatchery water supply and caused a 

 heavy loss of fish. Wliile this loss was serious for the present season, 

 it is being easily controlled by the installation of a suitable valve. 



NEW ENGLAND STATIONS 



The Nashua, N. H., station carried on its activities in a normal 

 manner with production approximating that of previous years. 



At the Hartsville, Mass., station the full requirements for its own 

 brook trout egg supply were met from the station's brood stock and 

 over 300,000 were shipped elsewhere. A new cement dam was con- 

 structed for one of its rearing ponds and other improvements effected. 

 The most outstanding feature was the collection, in cooperation with 

 the State of Connecticut, of over 580,000 smaUmouth bass fry from 

 lakes in Connecticut which are closed to fishing. The fish obtained 

 in this manner w'ere divided in equal proportions between the State 

 and the Bureau's applicants. 



The activities of the St. Johnsburv, Vt., station were centered at 

 the York Pond, N. II., auxiliary whiili has been under development 

 for a mnnber of years. The work at St. Johnsburv was confined to 

 cooperative rearing of fish in conjunction with the State of Vermont. 

 At the York Pond establishment the egg collections of brook trout 

 amounted to over 9,700,000. In addition to the fish-cultural work at
