200 REPORTS OF INVESTIGATIONS AND PROJECTS. 



[The Carnegie left Falmouth, under the command of Mr, Peters, on No- 

 vember 9 and arrived at Funchal, Madeira, on November 24. She goes next 

 to Bermuda, and returns to New York January, 1910.] 



The Carnegie has already attracted considerable attention, accounts of her 

 novel construction and of her work appearing in newspapers and periodicals 

 in many countries. The two points of special interest are : 



First, the fact that she has been constructed, inclusive of her machinery, 

 practically without iron or other metals affecting the compass. 



Secondly, that a type of marine propulsion — an internal-combustion engine 

 operated by producer-gas — has been installed as auxiliary to her sailing 

 power, which if proved successful will be of great practical importance, since 

 it will be the most economical form of marine propulsion now known. The 

 difficulty of successful operation of this type of propulsion has been some- 

 what enhanced in the case of the Carnegie on account of the necessity of 

 using almost entirely non-magnetic metals. Still, the present indications are 

 that the problems involved will be successfully overcome. 



The Department was fortunate in securing, through the courtesy of Prof. 

 J. A. Holmes, in charge of the technological branch of the U. S. Geological 

 Survey, the services of Mr. Carl D. Smith, expert in gas-engines, during the 

 period of trial of the installations on the Carnegie in Long Island Sound and 

 on the trip to St. Johns. Furthermore, Mr. D. F. Smith, a graduate of the 

 University of Maine in the department of mechanical engineering, who had 

 obtained besides practical experience in Professor Holmes's division in the 

 operation of gas-engines, was appointed chief engineer on board the Carnegie. 



The vessel has been described in a souvenir pamphlet prepared for distri- 

 bution at the time of the launching and reprinted in the June number of the 

 journal "Terrestrial Magnetism." 



In conclusion, some reference ought to be made to the splendid cooperative 

 spirit shown by those who had any part in the construction of the Carnegie. 

 Everyone appeared to take an interest in her far beyond any purely commer- 

 cial view. This was true not only of the architect and builder — the Institu- 

 tion having been most fortunate in their selection — but also of the various 

 subcontractors and of the firms supplying the materials, as well as of the 

 foreman and laborers engaged on the construction of the vessel. 



Her total cost, fully equipped, was in round numbers $115,000. 



The personnel of the Carnegie consists of the following : 



ScientiHc staff: L. A. Bauer, director; W. J. Peters, in command of vessel; J. P.Ault, 

 magnetician; C. C. Craft, surgeon and magnetic observer j E. Kidson, magnetic ob- 

 server; R. R. Tafel, magnetic observer; D. F. Smith, chief engineer. 



Sailing staff: C. E. Littlefield, saiHng master; H. T. Bartlett, first officer; M. Clausen, 

 second officer ; eight seaiTien ; one mechanic ; two cooks.
