1896] Rookery Surveys 



his drawings very spirited, so that the total had a 

 distinct value for subsequent investigations. But First /;- 

 his estimate as to numbers (based on the space mateas to 

 occupied by the rookery as a whole, divided by the 

 number of square feet assumed to be covered by 

 one individual) I always thought far too high - 

 an opinion recently verified by the measurements 

 of G. Dallas Hanna, now curator of Invertebrate 

 Paleontology in the California Academy of Sciences. 

 In 1891, in preparation for the Paris Tribunal of 

 1893, Mr. Elliott made a second trip to Alaska. 

 From this he returned with a bitter animus against 

 the North American Commercial Company (which 

 as lessee of the islands had succeeded the Alaska 

 Commercial Company) and with the strong ob-

 destruction lay in pelagic sealing. 



At the time of my appointment I was notified that two of .1/v 

 the ablest naturalists of the United States National Museum, Associates 

 Leonhard Stejneger (mentioned in earlier pages) and Frederic 

 A. Lucas, would be commissioned as my associates; also that 

 the U.S.S. Albatross under Jefferson Moser of the Navy, and 

 with Charles H. Townsend as naturalist, had been assigned 



1 C. Hart Merriam and Thomas C. Mendenhall, then Barton W. Ever- 

 mann, and (later) Frederick W. True and Charles H. Townsend all to the 

 Pnbilofs; and Leonhard Stejneger to the Commander group.
