for 1878—the last year of the existence of the Geological and 
Geographical Survey of the Territories. Though this mode of 
annual publication necessarily involves incompleteness, and is apt 
to overload the reports with unimportant detail, there can be no

they refer, will serve as the basis of all subsequent work. It is 
not without regret that one can regard the cessation of these vol- 
umes. On this side of the Atlantic, where they can be calmly 
considered apart altogether from scientific rivalry and political 
entanglements, they have been received with general approbation. 
It is impossible not to be struck by the largeness of the plan con- 
ceived by Dr. Hayden for the scope of his survey. Not geology 
merely but every branch of inquiry touching the natural history, 
archeology, geography and meteorology of the Territories, was 
embraced within his plan, and has been illustrated as far as the 
Means at his disposal would allow. To have conceived this 
broad and scientific scheme, and to have possessed the adminis- 
trative power to secure and keep in working concert so large and 
able a body of observers, are qualities of no mean order, and 
deserve grateful recognition wherever an intelligent interest is 
taken in the general progress of science and in that human 
advancement which scientific progress insures.”
