16 MEMOIRS OF THE NATIONAL ACADEMY OF SCIENCES. 



As our voyage and our subsequent stay on Caroline Island were something out of the run of 

 common experience, you will allow me to give some details concerning them, which usually do not 

 form a part of a scientific report. 



II.— ORGANIZATION OF THE EXPEDITION. 



The American party consisted of Edward S. Holden, director of the Washburn Observatory, 

 Madison, Wis.; Charles S. Hastings, professor of physics in the Johns Hopkins University, Bal- 

 timore, Md.; Charles H. Rockwell, Tarry town, N. Y.; E. D. Preston, aid United States Coast 

 and Geodetic Survey, Washington, D. C; Winslow Upton, United States Signal Office, Wash- 

 ington, D. C; Ensign S. J. Brown, U. S. N., United States Naval Observatory, Washington, D. C. 



The original six members of the party were joined on April 20 by four volunteer observers, 

 all officers of the U. S. S. Hartford. These were, Lieut. E. F. Qualtrough, U. S. N.; Passed 

 Assistant Surgeon W. S. Dixon, U. S. N.; Midshipman W. B. Fletcher, U. S. N. ; Midshipman

On March 11, the party was strengthened by the ioining (at Colon) of the two English gen- 

 tlemen who were sent out by the Royal Society of Loudon to make photographic observations of 

 the eclipse, under instructions from J. Norman Lockter, Esq., F. R. S., and Cajitaiu W. de W. 

 Abney, Royal Engineers, of the Science and Art Departmeut of the South Kensington Museum. 

 These were 0. A. Lawrence, London, England; C. Ray Woods, London, England. 



During our stay on Caroline Island (April 21 to May 9), the following petty officers and men 

 of the Hartford remained with ns and rendered very intelligent assistance : Horace Yewell, 

 seaman-gunner; Charles Emms, carpenter's mate; Peter Murphy, cariienter; John Smith 

 seaman; J. C. Harold, seaman ; C. A. Perkins, ordinary seaman (apprentice); James McKenna, 

 ordinary seaman (apprentice) ; Peter Burns, steward ; Thomas G. Brooks, assistant steward ;

III.— JOURNEY FROM NEW YORK TO CAROLINE ISLAND AND RETURN. 



(New York to Colmi, 1,989 miles; Colon to Callao, l,7i!2 miles ; Callao to Caroline Island, 4,324 miles; Caroline Island 

 to Honolulu, 2,100 miles; and from Honolulu to San Francisco, 2,092 miles.) 



By Prof. E. S. Holden. 



The six members of the American party sailed from New York March 2, 1883, on the Pacific 

 Mail steamship Acapulco (Capt. W. Shackford), and arrived at Colon March 11, after touching 

 at Castle Island, March 7, to send off a mail. At Colon the exijedition was joined by the English 

 photographic party. As the steamer on the west coast of South America did not leave until the 

 evening of March 12, the American party remained in Colon till the morning of that day, and 

 went from thence to Panama. Both in Colon and in Panama we were indebted to the courtesy 

 of Capt. J. M. Dow, of Panama, for expediting our movements and for personal favors. 



At Panama I telegraphed to the United States and also to the admiral commanding the 

 Pacific squadron. Through the kindness of my ftiend Clarence Gary, Esq., of New York, I 

 found that all our telegrams over the lines along the west coast of South America and through 

 to the United States were sent free of charge. Early in the morning of March 13 we sailed on 

 the P. S. Navigation Company's steamer Bolivia (Captain Ferguson), for Callao, stopping at 

 Buenaventura (March 14), Tuniaco (March 15), Guayaquil (March 17), Payta (March 18), and arrived
