PREFACE 



The "History" by Victor B. Scheffer and Ethel I. Todd was completed in 1967 and 15 mim- 

 eographed copies were produced and distributed to the staff of the then Marine Mammal Divi- 

 sion, now National Marine Mammal Laboratory, Northwest and Alaska Fisheries Center 

 (NWAFC), National Marine Fisheries Service (NMFS), Seattle, Wash.; the Pribilof Islands 

 Program, NMFS Northwest Region, in Seattle and on St. Paul and St. George Islands; and 

 NMFS Headquarters, Washington, D.C. 



The value of the "History" to researchers has long been recognized and to make this infor- 

 mation readily available it is being published as written in 1967 with only minor revision of the 

 Literature Cited section to conform to present citation procedures. 



Scheffer provided corrections to textual errors and with Clifford H. Fiscus, National 

 Marine Mammal Laboratory, NWAFC, reexamined and selected photographs to accompany 

 the text. Roger E. Pearson, Samuel Waterman, and Rae Mitsuoka, Publication Program, 

 NWAFC, edited the volume rearranging citations to conform to current practice. A Louise 

 Irwin, National Marine Mammal Laboratory, NWAFC, typed the manuscript and with Fiscus 

 verified citations and proofread the manuscript. Leola Hietala, National Marine Mammal 

 Laboratory, NWAFC, typed and assisted in the final production of the manuscript.
