Powerful and the Gladisfen for our work. W. R. Perin- 

 chief oversaw all the host of details of machinery installa- 

 tion, and Captain James Sylvester for the third year spent 

 a worried month, responsible for the capable working of 

 the crew of the Ready, the efficient interdigitation of the 

 boilers and winches, and especially the smooth running out 

 and in of the main steel cable itself, once almost off the 

 drum, and down to three thousand and twenty-eight feet. 

 Almost all the pronouns "I" in this book should be con- 

 sidered as divided into four, consisting of the permanent 

 Staflf of the Department of Tropical Research; John Tee- 

 Van, General Associate, Gloria Hollister, Research Asso- 

 ciate, Jocelyn Crane, Technical Associate, and myself. 

 Seldom, I think, have four human beings pulled so well 

 together with a single object in mind — the discovery and 

 recording of new facts and phases of nature, to the greater 

 honor of our special departmental niche in the New York 

 Zoological Society.
