SPECIAL REPORTS. 
On July 2, 1892, in response to a resolution of the United States Senate 
for information concerning the salmon fisheries of Alaska, a report was 
transmitted to the Senate (Mis. Doe. 192, Fifty-second Congress, first 
session) discussing the origin and development of the fisheries, statis- 
tics of the fisheries, present condition of the fisheries, methods and 
apparatus employed, the protective regulations of the fisheries, and 
recommendations as to further legislation in reference thereto. This 
report will also be found in the Bulletin of the United States Fish Com- 
mission for 1892. 
LIBRARY. 
The accessions to the library, which were mainly by donation and in 
exchange for the publications of the Commission, embraced 1,064 books, 
of which about one-fourth related directly to fish and fisheries, and the 
balance to zoology, natural history, and kindred subjects. 
OFFICE OF ARCHITECT AND ENGINEER. 
While under orders to make investigations of certain localities in 
Montana offering advantages for the location of a fish-cultural station, 
Mr. Charles E. Gorham, the architect and engineer of the Commission, 
died at Bozeman, Mont., November 13, 1892. For the purpose of secur- 
ing a competent engineer to fill the position thus made vacant, the 
United States Civil Service Commission held a special examination for 
applicants, and upon their certification Mr. Hector von Bayer was 
appointed thereto on March 1, 1893. 
The following is Mr. Von Bayer’s report, showing the work of con- 
struction at the different stations of the Commission during the year: 
Green Lake Station, Maine.—The two settling reservoirs were finished; a number 
of new rearing ponds were excavated; a branch box flume was laid, which taps 
the main supply flume, for feeding the new ponds, and a system of outdoor rearing- 
troughs and tubs; new drains from the ponds and troughs were laid; a number of 
buoys were placed in Green Lake for safer navigation; a new screen-gate was put 
at the foot of Green Lake to prevent the escape of fish; a portion of the road leading 
through the grounds was graded; a brick cistern was built in the superintendent’s 
quarters and one in the foreman’s quarters; minor repairs were made to the superin- 
tendent’s cottage, such as strengthening the first floor by additional posts, strengthen- 
ing the roof construction by additional collar-beams, and walling up the foundation 
of the earth closet; the siding and roof of the ice-house were repaired; the dam at 
Mountainey Pond was strengthened and leaks in the main supply flume were stopped.
