vi PREFACE 



Vincent Astor, the American Museum, George 

 F. Baker, Jr., Arthur T. Newbold, Thomas S. 

 Yates and Junius S. Morgan. Other gifts to be 

 recorded are a sounding machine from William H. 

 Trotter; sets of oceanographic books from 

 Frederic C. Wolcott; motion picture negatives 

 from George Eastman; flashlights and batteries 

 from the National Carbon Co.; a powerful radio 

 set from the Stromberg-Carlson Mfg. Co. and the 

 launch Pawnee from Harry Payne Bingham. To 

 Ernest Lester Jones, Chief of the Coast and 

 Geodetic Survey, I am obliged for a host of kind- 

 nesses and the loan of valuable instruments, and to 

 the U. S. Fisheries Bureau for the Albatross 

 launch and much valuable gear. 



The entire responsibility for the sea-going con- 

 dition of the Arcturus, her complete overhauling 

 and the supervision of the building of laboratories, 

 dark-rooms, refrigerators and oceanographic ap- 

 paratus was assumed bj^ Mr. J. R. Gordon and the 

 naval architect, Edwin C. Bennett. Capt. Yates 

 acted throughout for Mr. Wilhams, and it is to 

 the whole-hearted enthusiasm and interest of these 

 gentlemen that the smoothness of operation and 

 general success of the mechanical basis of the ex- 

 pedition was due.

 Laughlin I have nothing but single-minded praise. 

 No more willing, patient and capable seamen ever 

 existed.

 for more or less brief stages, among them being
