As the tarred felt roof of the hatchery had commenced leaking, a 

 shingle roof was substituted during the summer. In the following 

 spring a sea wall, 120 feet long and 5 feet high, was built along the south 

 side of the building to prevent the encroachment of the bank at its 

 rear. The material used for this wall consisted of 8-inch cedar posts, 

 4 inches by 4 inches by 10 feet white-oak wales, and oak planks 2 

 inches thick. Another section, 32 feet long and 4 feet high, was built 

 along the north side of the boiler house, and another along the north 

 side of the cottage, to afford protection against the encroachments of 

 the river. Considerable damage having resulted to the wharf during 

 the winter, it became necessary to refloor it and to drive a number of 

 white-oak piles at the corners as a protection against ice. 



Fish Ponds at Washington, D. C. (Dr. Rudolph Hessel, Superintendent). 



As a result of the work at this station during the fiscal year 44,465 

 large-mouthed bass, 100 small- mouthed bass, 3,662 crappie, and 3,000,000 

 shad were distributed in the fall months! Of the large-mouthed bass 

 39,000 were produced in the north pond, which has an area of about 

 3J acres. The remaining 5,405 were taken from the west pond and are 

 supposed to have been derived from a few late-spawners placed in one 

 of the i)artitions of this pond in June. In view of the exceedingly poor 

 results attained with the small-mouthed bass, it seems useless to 

 continue experimenting with these fish at this station. Early in the 

 summer the south pond, which has been devoted to their culture for 

 several years, was estimated to contain about 4,000, but the number 

 dwindled gradually and when the pond was drawn down in August 

 only 160 remained. 



The experiments with crappie were continued in ponds 20 and 5, and 

 3,662 were available for distribution in October. These were fed on
