In bringing to a close the account of my labors, and those of my 
assistant, the past season, I cannot but express a wish that more 
had been done for the advancement of the objects of the survey, 
than appears on these sheets; yet, considering the peculiar disad- 
vantages under which we have labored, we cannot but flatter our- 
selves that as much is accomplished, perhaps, as can reasonably be 
expected. If it is not so, it is not because we have not been desi- 
rous of it, neither has it been for want of diligence on our part. 
In an appendix I have inserted a list of a few minerals from loca- 
lities not given to the public liefore. 
This, together with the foregoing account, is respectfully sub- 
mitted.

NOTE TO PAGE 104. 
The Notch here mentioned, is an immense gorge, or chasm, furnishing dLpass through 
these high mountains; on one side the precipice of solid rock, before mentioned, rises 
perpendicularly more than 1,000 feet; on the other side rises a steep mountain, which 
attains an elevation of more than 5,000 feet. The north, or principal branch of the Hud- 
son, takes its rise in this notch, as also does the south branch of the Au Sable; the for- 
mer flows south, and the latter north. These two streams rise so near each other, that 
during freshets their waters mingle.
