176 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



hydrographic work was impracticable ; and though these in- 

 vestigations were entirely subsidiary to the regular work, 

 they were crowned with unexpected success, especially in the 

 departments of botany and geology, and the various groups 

 of marine invertebrates. 



These collections, although still but superficially examined, 

 indicate a curious resemblance in some particulars between 

 the fauna of the region visited and that of the Straits of Ma- 

 gellan, a number of forms found being common to both, and 

 not yet 'discovered in the intervening regions. 



SURVEY OF THE NORTHERN BOUNDARY OF THE UNITED 



STATES. 



The detail for the joint survey of the northern boundary 

 of the United States, between the Lake of the Woods and the 

 Rocky Mountains, has been completed, and a party rendez- 

 voused at St. Paul on the 5th of August. The American 

 branch of the expedition consists of Mr. Archibald Campbell, 

 commissioner, with Major Farquhar, chief of the survey ; Cap- 

 tain Twining, chief astronomer ; Lieutenants Gregory and. 

 Green, and four engineer officers, with Professor Clarke and 

 L. Bass, assistants in the astronomical department. 



During the present season the survey will probably be oc- 

 cupied on that portion of the line between the Lake of the 

 Woods and Pembina ; the precise determination of the lati- 

 tude of the latter being of great importance, since a conflict 

 of jurisdiction has already arisen in reference to the Hudson 

 Bay Company's post close by. A complete equipment of ap- 

 paratus has been provided, and every effort will be made to 

 render this work not inferior to others prosecuted under the 

 direction of the United States government. Washington

EXPLORATIONS OF BECKWITH AND ELDER IN THE BAY OF 



FUNDY. 



Among other explorations made during the present year 

 may be mentioned that undertaken in the upper part of the 

 Bay of Fundy by Captain 1ST. W. Beck with, of Hantsport, and 

 Professor William Elder, of Acadia College, Nova Scotia. 

 Their labors were prosecuted principally in the Basin of Mi- 

 nas, and consisted in dredging and other investigations in the
