rnary of the work of the Survey during the year. It includes 

 the determination of longitude in Alaska, both on tbe coast and 

 in the interior, by tbe telegraphic method ; the examination of 

 the boundary lines between Alaska and Canada, and also between 

 Canada and the New England States, were both carried forward. 

 The magnetic survey includes observations at 382 stations and 

 also contains records of the observations at the permanent obser- 

 vatories at Cheltenham, Md., Baldwin, Kans., Sitka, Honolulu, 

 and Vieques, P. R.; special observations were also made during 

 the solar eclipse of August 30th. These observations are given 

 in Appendices 3 and 4.
