THIRD ANNUAL REPORT 
Of E. Emmons, of the survey of the Second Geo- 
logical District 
To his Excellency y William H. Seward, 
Governor of the State of JYew-York: 
Sir — Owing to many inaccuracies in the county maps of the Second 
Geological District, and to the incomplete state in which the original 
surveys which constitute the foundation of those maps were left, espe-

the great water courses of the State, I was directed by his Excellency, 
Wm. L. Marcy, to attempt those corrections and supply those deficien- 
cies, which are of the most importance to the geological survey. 
This additional duty, while it has interfered with, and retarded, to a 
certain extent, the prosecution of my appropriate labors, has not caused 
at any time their entire suspension. The consequence has only been, 
that I have not been able to complete the examination of so much terrij 
tory as I should have done had my attention been directed solely to the 
collection of geological facts. 
It remains to be shown in the final result whether this course was 
judicious, though it can hardly be doubted that it is important that the 
proposed geological maps should be as full and accurate in geographical 
details as possible. 
During the first season of the survey, Mr. Hall and myself ascer- 
tained the fact that by far the most elevated portion of the State is 
situated in the Second Geological District. 
This circumstance gave an unusual interest to this section, and has 
induced already many gentlemen to visit this region of mountain; and 
it will undoubtedly in a few years become a favorite place of resort to 
persons of leisure. The location, too, of the Adirondack iron works,
