DEPARTMENT OF TERRESTRIAL MAGNETISM. 307 



MISCELLANEOUS. 



Desired preparations have been made for the proposed exhibit in the 

 Administration Building next December and at the Panama Exposition. 

 Besides some of the typical instruments of the Department's design 

 and make, there will be photographs, a globe, and an admirably 

 executed 4-foot model of the Carnegie, made by the Boucher Manufac- 

 turing Company of New York, upon special order from the Institution. 



In conclusion, grateful acknowledgment should be made of the 

 many courtesies received by our various field parties from government 

 officials and diplomatic officers. Often special arrangements were 

 made, military escorts or traveling facilities being provided and most 

 helpful letters of introduction being supplied. 



DETAILS OF OBSERVATIONAL WORK. 

 OCEAN WORK. 



On November 1 the Carnegie was en route from Falmouth, England, 

 to New York. On account of heavy weather she put in at New London, 

 Connecticut, on December 14, and was towed to Greenport on Decem- 

 ber 15. After reoccupying the repeat stations at Greenport and Shelter 

 Island, the party left for Brooklyn on December 18, and the vessel 

 was berthed at Beard's yacht basin, Brooklyn, on December 19. The 

 Director inspected the vessel here and conferred with Captain W. J. 

 Peters regarding the repair work required after the three years' con- 

 tinuous cruise of the Carnegie. After a careful consideration of the 

 various proposals received, it was decided to have the necessary repairs 

 made by Tietjen & Lang, of Hoboken, New Jersey, under the imme- 

 diate supervision of Mr. Peters, as the representative of the Depart- 

 ment. The Carnegie was accordingly towed to the Tietjen & Lang 

 shipyard on February 24. The repairs to the hull, required by the 

 dry rotting of timbers which had set in, were completed on April 10, 

 and the vessel was then towed back to Beard's yacht basin. The 

 stone ballast, previously used, was replaced by lead ballast, and other 

 repairs and alterations were made in accordance with the experience 

 gained on the previous cruises. On April 6 Mr. R. E. Storm was 

 engaged as mechanical engineer. We were fortunate in being able to 

 avail ourselves also, for a few days, of the expert assistance of Mr. 

 C. D. Smith, of the United States Bureau of Mines. The refrigerating 

 plant and oil engine were overhauled and some minor, tentative changes 

 were made in the producer gas engine. 



Meanwhile the plans had been made for the third cruise of the 

 Carnegie, to be this time wholly in the northern Atlantic Ocean. The 

 command of the vessel was transferred on June 1 from Mr. Peters to 

 Mr. J. P. Ault, Mr. Peters having been placed in charge of the impor- 

 tant expedition to Hudson Bay, an account of which is given below.
