WORK OF THE CARNEGIE AND SUGGESTIONS FOR FUTURE SCIENTIFIC CRUISES 



meters radius surrounding the selected position. This 

 limitation was used on the German Steamer Gauss and 

 the so-called "constant" part of the deviations that is 

 difficult to control usually was less than 1° for both 

 declination and inclination. Details regarding location 

 of laboratories needed for atmospheric electricity, for 

 chemical analysis, and for biological work in the design- 

 ing of a vessel would be arranged best after the archi- 

 tect's preliminary plan had been drawn in which the lo- 

 cations had been made in conformity with requirements 

 herein stated. The accommodations for scientific per- 

 sonnel should be planned in anticipation of future in- 

 creases after mature consideration of a possible future 

 expansion in oceanographic work. Subsequent additions 

 to quarters rarely can be made without sacrifice of ven- 

 tilation, light, or comfort. 



Plans of other vessels which have been engaged in 

 oceanographic work would supply many ideas of details 



of arrangement that might be overlooked without such 

 guides. Among these are the plans of the Carnepie . the 

 German steamers Gauss and Meteor , the Discovery n 

 (4), and some of the U. S. Coast and Geodetic Survey 

 vessels. 



The U. S. Shipping Board publishes a monthly peri- 

 odical list of its vessels for sale. These are all steel 

 and of several thousand tons dead-weight, too large for 

 economic operation. Yacht brokers of New York at one 

 time published a list of yachts for sale, but this has been 

 discontinued and each broker supplies the information on 

 request. The foreign edition of Fairplav (3), a weekly 

 published in London, gives list of sales consummated in 

 English and foreign ports, also advertisements of ves- 

 sels for sale. It might be worth while noting that a sec- 

 ondhand wood hull, if in sound condition, is less liable to 

 dry rot than new construction.
