100 MAGNETIC OBSERVATIONS 



determining the magnetic declination, dip and relative intensity : At Nassau, 

 on the grounds of the old Government House; at Watlings Island, the sup- 

 posed landing place of Columbus in 1493 ; and at Clarence Town, Long 

 Island. Observations for the determination of declination only were made on 

 Hog Island, just across the harbor from Nassau, and very close to the former 

 station occupied in 1879 by Lieut. Ackley; in the Public Square at Nassau, 

 where a meridian line was utilized, which was established by Mr. Miller, the 

 Surveyor-General of the Islands. At Hopetown, Abaco Island, declination 

 and dip observations were made. 



The results of the observations described above, and reduced under the 

 direction of the Superintendent of tlie Coast and Geodetic Survey, are shown in 

 Tables II and III. A detailed description of the stations occupied, and of the 

 preliminary results obtained, follows in the chronological order of occupancy.^ 



Nassau: Old Government House. 



The station is on the grounds of the old Government House, built by the 

 first governor of the Islands. The property was for many years, until re- 

 cently, used as a government hospital. About six or eight years ago it was 

 purchased by the Catholic Church and the building is now the residence of 

 the local priest. 



The exact locality of the station is marked by means of five copper nails, 

 driven into the bed rock, about 75 feet west-northwest from the northwest 

 corner of the building. These nails are covered by means of a slab about 

 one foot square, with the inscription " Bahama Expedition, 1903." The 

 location of the station was further fixed by sighting upon three points, Hog 

 Island Lighthouse to the north, the Obelisk to the west, and the northwest 

 edge of the Priory. 



The mark used was the tip of the Obelisk at Fort Charlotte. Its true 

 azimuth was found to be 86° 47.4' west of true north. 



Complete observations were made at this point on June 30, 1903, and 

 July 2, 3, 4, by the writer, and recorded by J. E. Eouth. 



Hog Island, on the North Side of the Harbor of Nassau. 

 Observations to determine the magnetic declination were made about 

 30 to 35 feet west-northwest of the stone monument marking tlie southwest 



^ The descriptions of stations occupied, and tlie final results of the computations 

 as given in Table II. are published in the Annual Report of the Superintendent of 

 the U. S. Coast and Geodetic Survey for the year 1903-4, Appendix No. 3, p. 254.
