Bulletin for 1904. 



There were sent out during the year 2,513 bound and 16,166 pam- 

 phlet publications of the Bureau. The principal recipients of the 

 publications are libraries, institutions of learning, collaborators, and 

 specialists; but aside from these there is a large and increasing demand 

 for the various articles from persons interested in the particular phases 

 of the fisheries therein discussed. Requests are received daily for 

 certain publications the supply of which has been exhausted, the 

 demand for the Manual of Fish Culture being particularly active. 

 Two editions of this very popular and useful work have been entirely 

 distributed, and another edition should soon be provided. 



The library has been increased by the addition of 159 bound vol- 

 umes and 307 unbound volumes and pamphlets, these, as usual, being 

 works pertaining to the special needs and functions of the Bureau. 



EXPOSITIONS. 



The exhibit of the Bureau at the Louisiana Purchase Exposition at 

 St. Louis, which came to a close December 1, 1904, won favorable 

 comment. The fisheries building was unique in design, and lent itself 

 to an advantageous and attractive installation. It was 136 feet square, 

 with a central court 74 feet square, having in the center a pool 24 feet 

 square open to the sk} r . In the court was arranged the general exhibit, 

 and separated from it by screened corridors 15 feet wide was the 

 aquarium, extending around the building. The aquarium tanks, 40 in 

 number, were along the walls and lighted from the rear; the corridors 

 being in semidarkness, the animals in the tanks were plainly visible. 

 and the general effect was pleasing to the eye. The machinery room, 

 containing pumps, motors, filters, refrigerating machine, etc., and the 

 reservoirs of fresh and salt water were underneath the main floor. 



In the aquarium were kept the fresh and salt water fishes propagated 

 by the Bureau and such other important and curious fishes and water 

 animals as it was possible to obtain and transport. From 100 to 150 

 species were always in the tanks, and were constantly renewed by fresh 

 supplies brought from different parts of the country in the care of the 

 Bureau. The Illinois state commission contributed to the interest of 

 the display by maintaining in one of the large tanks a fine collection of 

 the river fishes of that state. The central pool contained seals, sturgeon, 

 large catfish, and various kinds of turtles.
