of the place in which I had secured the ship for the winter; which, 

 connected with Mr. Martin's and my own observations on the coast 

 to the westward, will, I hope, give a tolerably correct representation 

 of these shores, and when associated with magnetic observations on 

 every attainable point, will, I trust meet their Lordships' approba- 

 tion." 



The results foreshadowed by this report have not come to light. 

 No map or plan of Emma Harbor, or Plover Bay, has been pub- 

 lished by the British Admiralty Office, and no statement or account 

 of the observations at Plover Bay, if any were made. General 

 Sabine in his contributions to Terrestial Magnetism No. XIII gives 

 some results which he credits to a MS in the Magnetic Office by 

 Commander Moore, but no magnetic declination or intensities are 

 given ; whence we conclude that no observations, or at least no satis- 

 factory observations, therefor, were taken. A few results for dip 

 are given. The geographical position of the station where the dip 

 observations were taken is given by General Sabine, and this posi- 

 tion, if due to Commander Moore, is the earliest determination on 

 record of a position for Plover Bay. The position given probably 

 refers to some point near the northern shore of Emma Harbor 



and is 



Latitude, 64 26' N. 

 Longitude, 173 07 W. Gr. 



and the observed dip was 75° 10'. From the best existing chart 

 of Plover Bay that we have, it is found that this station is four 

 minutes north, and nine minutes east of the station occupied by the 

 Coast Survey. Whence we find the Coast Survey Astronomical 

 Station to be, according to Commander Moore, approximately in 



Latitude, 64 22' N. 

 Longitude, 173 16 W. Gr. 



A rough sketch of Plover Bay was made in 1866, by the explor- 

 ing parties of the Western Union Telegraph Company, and this 

 sketch was published in 1869 by the Coast Survey. The obser- 

 vations were made by Lieut. J. Davison, of the U. S. Revenue 

 Marine Service, and the resulting position is stated to depend 

 upon nine observations referred by a crude triangulation to the 

 mountain Bald Head. The position given by Lieut. Davison for 

 Bald Head is 



Latitude, 64 24 / N. 

 Longitude, 173 15 W. Gr.
