xc GENERAL SUMMARY OF SCIENTIFIC AND 



of 114 5', which, with the work done many years ago under 

 Colonel Graham and others, makes a continuous survey from 

 ocean to ocean. There still remains the demarkation be- 

 tween Alaska and the British Possessions in North America, 

 which it is hoped may be undertaken before long. 



Various other enterprises in the way of demarkation of 

 interstate and territorial boundaries have been prosecuted 

 during the year; but it is hardly necessary to bring them un- 

 der review. We may, however, here mention the proposed 

 enterprise by the State of Massachusetts in the way of a new 

 physical and scientific survey of its territory. It will be re- 

 membered that Massachusetts was one of the first states, 

 nearly forty years ago, to undertake such a labor, which was 

 accomplished as fully as the means of research then available 

 would permit. It now proposes to take the initiative in a 

 renewed investigation of the same character, to include a 

 thorough examination into the fauna and flora of the state. 

 It is to be hoped that this will be carried out, and that so 

 worthy an example will be imitated by other states. 



In concluding our notice of geographical operations in 

 North America, we may refer in general terms to the labors 

 of the United States Engineer Bureau, of which particular 

 reference has been made in connection with the expeditions 

 of Lieutenant Wheeler and Maior Twining. Anions: the 

 more prominent publications of the Bureau during 1874 are 

 Maps of the Military Department of Missouri, embracing 

 parts of Colorado, Kansas, Nebraska, and the Indian Terri- 

 tory; of the Ute country; New Mexico; the Military De- 

 partment of the Platte ; Nebraska ; Wyoming ; a general 

 Military Map of the United States, showing the territories 

 west of the Mississippi River ; Chart of Lake Superior, in 

 three sheets ; Reconnoissance for a wagon road from the 

 Pacific Railroad to Yellowstone Park and Montana, in fifty 

 sheets; Maps of Sandusky Bay; St. Lawrence River; Lake 

 St. Clair, and numerous charts of rivers and harbors in con- 

 nection with river and harbor improvement, mostly upon 

 the Great Lakes ; as also a progress chart of survey of North- 

 ern and Northwestern Lakes, and a sketch of the complete 

 triansfiilation in Wisconsin and Michigan.
