REPORT 
OF THE 
SURVEY OF THE FIRST GEOLOGICAL DISTRICT. 
CHAPTER L 
INTRODUCTION. 
In developing the geology of the First District of New-York, I have made such progress 
as my opportunities have permitted ; and although little has been accomplished, when com¬ 
pared with what remains open for investigation, the results of these labors may be of some 
value to the community, as tending to make known the nature of the materials on a small portion 
of our planet, their position, uses, relative ages, and some of the various physical changes 
that this portion of the earth’s surface has undergone. 
The labor of investigating the rocks in the first district is much greater than in the others, 
in consequence of their having been broken up by some convulsive action, and turned edge¬ 
wise through extensive tracts of country, like ice, where broad fields of it crush against each 
other. This may seem visionary to those who have not investigated the facts of geology ; but 
all can examine the facts in evidence, and draw their own conclusions. 
The First Geological District embraces twenty-one counties, and extends from the north 
end of Washington county between Lakes Champlain and George, south we stwardly to the 
Susquehannah river; so as to include the counties of Washington, Saratoga, Schenectady, 
Schoharie, Delaware, and all east and south of this line that lie within the limits of the State 
of New-York.
