the reports of the Division of Scientifie Inquiry. 
The Cortland (N. Y.) hatchery does not maintain a brood stock, and 
all eggs handled were received from other stations. Brook, brown, 
rainbow and lake trout were propagated, and the results obtained 
were gratifying. Under the auspices of the N. Y. A. and W. P. A., 
extensive repairs and improvements were made to buildings, roads, 
and grounds. Summaries of the experimental activities and scientific 
investigations appear elsewhere. 
The Carpenters Brook unit, which is operated in cooperation with 
Onondaga County, collected eggs from its brood stock as follows: 
100,140 brook-trout, 147,750 brown-trout, and 14,630 rainbow-trout 
and 199,670 brook-trout eggs, and 35,000 lake-trout eggs were received 
from other stations. Approximately 75 percent of the resulting fish 
were distributed as fingerlings, and the remainder are being held for 
liberation as yearlings. 
COMBINATION TROUT AND PONDFISH STATIONS 
No trout eggs were taken at the Lamar (Pa.) hatchery this year. 
Eggs received from other points produced 1,180,150 trout, and ap- 
proximately 400,000 of these fish were transferred in the small finger- 
ling stage to the ‘Ogletow nand Alleghany National Forest substations 
and cooperative nurseries where they are to be fed until late fall and 
liberated in public waters. In addition to trout, the Lamar hatchery 
propagated 5 species of warm-water fishes—comprising largemouth 
and smallmouth black bass, yellow perch, catfish, and sunfish. The 
aggregate output of pondfishes was 44,230 fingerlings. This unit has 
15 completed ponds, each approximately 1 acre in area, and 3 under 
construction. Ponds were excavated and other improvements were 
made under the auspices of the W. P. A. and the C. C.C., and N. Y. A. 
employees also assisted with the general work. 
The Flintville (Tenn.) station received rainbow-trout eggs from the 
White Sulphur Springs (W. Va.) hatchery. In addition to 179,200 
3- and 4-inch fingerling rainbow trout for the stocking of Alabama, 
Georgia, Ohio, and Tennessee waters, 34,000 fingerlings were on hand 
at the end of the year. Largemouth black bass, smallmouth black 
bass, rock bass, and sunfish also were propagated. However, due to 
the small pond acreage available for the culture of warm-water species, 
the output of most of these forms was relatively small. Several 
thousand black bass and sunfish were received from the Marion (Ala.) 
hatchery and distributed for the stocking of central Tennessee waters. 
The successful artificial hatching of red-horse-sucker eggs engendered 
enthusiastic interest by the fishermen of this area. 
The Powder Mill Park (N. Y.) hatchery, which is operated in 
cooperation with Monroe County, maintained a stock of adult trout 
from which sufficient brook-, brown-, and rainbow-trout eggs were 
collected to meet its needs. In addition. to these three species,-lake - 
trout also were handled. This station reared practically its entire 
output of trout to yearling size before releasing them in the waters 
of Monroe County. Only 2% acres are available for the culture of 
pondfishes, yet 16,600 largemouth and 2,500 smallmouth black bass 
fingerlings were produced.
