the world; a Central Station at Washington, D. C., the home- 
quarters of the Commission, with laboratories for the study 
of embryology, the chemical composition of fish and its 
food-value and other important points, and with ponds in 
the City of Washington for the experimental raising of carp 
and gold-fish; and finally a permanent station at Wood’s 
Holl, Massachusetts, with wharves for the vessels of the 
Commission, laboratories for scientific investigation and a 
hatchery for cod and other sea-fish, at the centre of the 
most important fisheries along our Atlantic Coast. In addi¬ 
tion to these it is the custom, in summer-time, to set up 
temporary laboratories at convenient places. These are often 
attended by volunteers, students in biology, as affording 
them good summer practice. 
The Commission publishes an Annual Report of its work, 
with valuable papers by the scientists; among these are 
monographs upon the most important species, as the blue- 
fish, mackerel, menhaden, shad, salmon, white-fish, sword¬ 
fish, lobster and oyster. It also publishes a yearly Bulletin, 
giving the results of work by its investigators in the field. 
These, being Government publications, may be had gratui¬ 
tously by the public. 
The Commission lends its aid and encouragement to 
individual effort in all matters of Fish-culture: it co-operates 
with the State Hatcheries and with pisciculturists in every 
part of the world, and annually distributes millions of the 
eggs and fry of the Salmonidce , white-fish, shad, carp, sea- 
bass, black-bass, pike and many other species to State 
Hatcheries and to private fish-farms — and all gratis. It 
would be hardly possible for private enterprise to succeed 
in extensive experiments in the transplanting and acclima¬ 
tizing of new species in new waters, but the Commission 
can do so, thanks to its great facilities. Thus, it. has suc¬ 
cessfully planted the Atlantic salmon in its landlocked form 
and also the smelt in the lakes of the interior. It has 
attempted to place the California salmon in Eastern waters, 
though this experiment, as I shall show later, has hitherto
