shaped, covers about 2 acres of land, and is from 3 to 8 feet deep. 
The embankment on the north and west sides is 600 feet long, from 
20 to 30 feet wide at its base, and from 8 to 12 feet high. In order to 
protect it from high water, a piling wall 7 feet high was built along 
Tates Run and along the west end of the pond. On the east end the 
old road bed was raised from 4 to 6 feet and widened, so that it now 
serves not only as a wagon road but asa strong embankment for the 
pond as well. The water supply was obtained from Tates Run, 1,100 
feet above the pond, a 12-inch terra-cotta pipe laid in cement being 
run alongside the old pipe, through land belonging to R. G. Corvin. 
Between the two main pipe lines a 5-inch tile pipe was laid to carry off 
leakage and surface drainage, thus preventing injury to the lands for 
agricultural purvoses. 
In addition to the usual cribs, sereens, ete., for the outlet of water, 
which are situated in the northeast corner of the pond, a tight crib- 
like arrangement was constructed about midway on the east end of 
the pond, at the foot of the road embankment. Connected with this 
erib is an offshoot from the supply pipe for the old series of ponds, 
through which the main line is flushed. This is accomplished by 
withdrawing a plug from the end of the pipe by means of a lever. 
The water in flushing passes through the crib and enters a 12-inch 
pipe line connected at the other end, and is then conveyed to Tates 
Run. After flushing, the pipe is closed by reversing the lever. The 
overflow from the large pond passes into the series of ponds below, 
thereby increasing the water supply. 
After the completion of this pond, in October, a carpenter shop 15 by 
28 feet, 14 stories high, was built 50 feet west of the hatchery. The 
upper floor is used for the storage of cans, tools, and other material, 
and the lower one as a carpenter shop, meat room, etc. A number of 
other improvements were also made, such as the building of a porch 
6 by 30 feet on the south side of the hatchery, grading and sodding 
embankments, filling in old blind ditches, regrading and seeding to 
grass the small bottom east of the spring, building fences, painting 
buildings, ete. 
The fish-cultural operations for the year consisted in the propaga- 
tion and distribution of rainbow trout, brook trout, black bass, and 
rock bass. The distribution of fish hatched in the previous year 
commenced October 6 and continued to December 23, during which 
period 165,480 rainbow trout, 8,192 brook trout, 8,730 rock bass, and 
1,812 black bass were distributed; also 15,816 black bass and 800 
crappie were transferred from other points. 
The food used during the summer for the young and adult fish con- 
sisted of beef liver and mush, mixed in varying proportions, according 
to the size of the fish. 
In September a loss of 156 large breeding trout from suffocation 
occurred in one of the ponds. The water at the time was very low,
