REPORT 
Of W. W. Mather, Geologist of the the 1st Geologi- 
cal District of the State of New- York, 
To His Excellency Wm. L. Marcy, 
Governor of the State of Mew- York, 
Sir— 
.Since the first annual report, I have been engaged in making a 
reconnoissance of Ulster and Delaware counties, in tracins; some of our 
rock formations of Columbia, Dutchess, Putnam and Westchester coun- 
ties, to Virginia and North Carolina, and since the first of July, in 
making the detailed geological surveys of Queens, Kings, Richmond, 
Columbia and Dutchess counties. 
During the next season it is my intention to make the detailed sur- 
veys of the counties of New-York, Westchester, Putnam, Rockland 
and Orange, w^hich comprise most of the primitive rocks (as they are 
called) of my district. This intimation of my intentions is made thus 
early, so that persons owning property and wishing certain examina- 
tions to be made, may give notice in due season. Letters, post paid, 
addressed to W. W. Mather, Geologist of the 1st District, Albany, re- 
questing him to examine the mineral resources of property in those 
counties, will be attended to. 
A series of geological queries is appended to the report, with a view 
to elicit information from the people of the State, who take an interest 
in observing the phenomena of nature around them. 
Details and facts, belonging strictly to pure scientific geology, will 
not be made public until the publication of the final report. The ob- 
ject of the annual reports is to give publicity to such facts and localities 
as may be of practical utility, so that benefit may be derived from a 
knowledge of them, during the progress of the survey.
