EXTRACTS FROM FIELD REPORTS AND ABSTRACTS OF LOGS 



OF THE GALILEE. 



The following extracts from field reports made to the Director at the end of 

 each cruise by the respective commanders of vessel will serve not only to supple- 

 ment what has already been given, more or less briefly, on pages 8 to 14, but will 

 also be found to contain most interesting and valuable information as to the con- 

 ditions encountered, the work done, and the manner in which a cruise was accom- 

 pUshed. 



EXTRACTS FROM FIELD REPORTS. 



J. F. Pratt: Alterations of the Galilee, and her First Cruise. 



1. Beginning at San Diego, Cal., the scientific personnel of the ocean party in my charge was as 

 follows: J. F. Pratt, in command; Dr. Hobart Egbert, surgeon and observer; J. P. Ault, observer, 

 and P. C. Whitney, observer and watch officer. [The Director, Dr. L. A. Bauer, accompanied the 

 vessel on the experimental portion of the cruise from San Francisco to San Diego, during which he 

 supervised the arrangements for the scientific work, completed the training of the observers in the 

 magnetic work, tried out and devised the methods of observation, and decided on the final program 

 of work. Under his direction, also, Messers. Egbert and Ault made the required observations in the 

 vicinity of San Francisco for determining the magnetic elements at the locality selected for swinging 

 ship, and for the determination of magnetic constants of the various instruments and of the vessel.] 



2. My entire connection with the Department of Terrestrial Magnetism of the Carnegie Insti- 

 tution of Washington was as follows: Between April 16 and June 3, 1905, my services were of an 

 advisory nature, relating to weather conditions for the forthcoming cruise, the questions of stabihty, 

 construction of ordinarily composition-fastened vessels, with special reference to the amount of 

 iron in their hulls, suitable rig, reconstruction of quarters, and the recommendation of the use of a 

 specially constructed flying bridge. Between June 4 and December 17, 1905, at the request of the 

 President of the Carnegie Institution of W^ashington and by permission of the Honorable the Secre- 

 tary of the Department of Commerce and Labor, I was on leave of absence, without pay, from the 

 Coast and Geodetic Survey, and on annual leave granted by the Department of Commerce and 

 Labor from December 18 to 22, 1905, being under pay from the Carnegie Institution of Washington 

 from June 4 to December 22, 1905. Between December 23, 1905, and February 8, 1906, my services 

 were gratuitous; they consisted in conferring with the owners of the vessel regarding the changes 

 mentioned in paragraph 32, in acquainting my successor (W. J. Peters) with the condition and 

 necessities of the vessel, etc. Between February 9 and 28, 1906, I was again on leave of absence, 

 without pay, from the Coast and Geodetic Survey, and under pay from the Carnegie Institution of 

 Washington. 



3. On June 6, 1905, just after my arrival in San Francisco from Seattle, Washington, a confer- 

 ence was held with the owners of the Galilee, and an understanding arrived at as to the contemplated 

 changes and the manner in detail of carrying them out. 



4. The Galilee is a brigantine, her custom-house register being 354 gross and 328 net tons; length 

 132.5 feet, breadth 33.5 feet, depth 12.7 feet; crew 8; built in 1891 at Benicia, California. Her 

 general dimensions are approximately as follows: 



Feet 



Length over all, extreme 189 



Length over all, of hull 140 



Length on water line as ballasted for cruise 128 



Overhang, forward 3.5 



Overhang, aft 8.5 



Breadth, extreme 32 . 5 



Feet 



Draft, extreme as ballasted for cruise 10 



Freeboard bow 13 



Freeboard stern 10 



Least freeboard, including bulwark as ballasted. ... 8.5 



Height of fore truck above water line 120 



Height of main truck above water line 121 



The sails used during the present cruise consisted of the following: foresail, lower foretopsail, 

 upper foretopsail, fore topgallantsail, fore royal, jib, flying jib, outer jib, middle mainstaysail, 

 leg-of-mutton mainsail, ringtail maintopsail, and fore balloon-studding-sails; the combined area of 

 the foregoing being approximately 10,952 square feet.
