nearly 300,000 birds. They were arrested by the officers of the revenue 

 cutter, brought back to Honolulu, tried and deported to Japan and the 

 plumage was confiscated. Since this practical demonstration in bird 

 protection the colony has not been disturbed. 



Utilization of the Reservations 



National refuges are utilized for several purposes other than the 

 protection of birds, notably the preservation of other forms of wild life, the 

 study of certain problems connected with the migration and life history of 

 species, and the development of public sentiment in favor of wild life con- 

 servation. With the stopping of shooting on the Mosquito Inlet Reservation 

 protection was afforded aquatic mammals, as well as birds, and since this 

 order has been in effect manatees and porpoises have increased in the adja- 

 cent waters. Incidentally, it is interesting to note that Daytona at the 

 upper end of the Mosquito Inlet Reservation is the most northern point 

 at which the manatee occurs on the coast of Florida. On several of the 

 Pacific Coast reservations sea lions are afforded protection and on some of 

 the islands in the Hawaiian Reservation a rare and peculiar tropical seal is 

 one of the most interesting species. 



At the Deer Flat Reservation in Idaho experiments are being made to 

 ascertain to what extent birds can be protected and encouraged to breed on 

 a body of water which is used as a resort for visitors during summer. It is 

 expected that with reasonable restrictions on the use of boats on the reser- 

 voir the birds will become as tame as they are at some of the winter resorts 

 in Florida. At the Niobrara Reservation in Nebraska, which includes some 

 12,000 acres of land on the edge of the sand hills, within the former range of
