Another remarkable monntaiiij bearing N. 47^ was named Mount 
Mclntyre, It was supposed to rank next in height to Mount Marcy. 
Its true bearing from the Dial mountain is N. 66° 36' W. The bear-- 
ing of White Face from Mount Mclntyre, on the magnetic meridian is 
N. 20° E., and the Notch, or as it is now called j the Indian Pass, S. 
85° W. North Peak of Santanoni, S. 72° 30' W. and the South Peak 
S. 65° W. N. W. point of Lake Placid, N. 5° E.; L^ng Pond, in 
Keehe, N. 50° E. 
An insolated mountain, situated between Mount Marcy and Mount 
Mclntyre, has been named Mount McMartin, in honor of one now de- 
ceased, whose enterprize and spirit, in conjunction with two others, 
whose names it is unnecessary to mention, has contributed much to the 
establishment of a settlement at the great ore beds, as well as to other 
improvements, advantageous to the prosperity of this section of the 
State. 
A distant view of this mountain is given from Lake Henderson. It 
is particularly remarkable for its trap dyke, which is about eighty feet 
wide, and which has apparently divided it into two parts near its cen- 
tre. A portion of this dyke is visible from Lake Henderson, a distance 
of about five miles. A fine and spirited view of it has been furnished me 
by Mr. Ingham of New-York, who was one of the exploring party. It 
was taken near the base of the mountain, at Avalanche Lake, and is 
merely an exhibition of the termination of the gorge which has been 
formed by the breaking up of the dyke by a small stream of water, as- 
sisted by frost and other agents. 
The cluster of mountains in the neighborhood of the Upper Hudson 
and Ausable rivers, I proposed to call the Adirondack Groupy a name 
by which a well known tribe of Indians who once hunted here may be 
commemorated. 
It appears from historical records that the Adirondacks or AlgonquinSy 
in early times, held all the country north of the Mohawk, west of Cham- 
plain, south of Lower Canada, and east of the St. Lawrence river, as their 
beaver hunting grounds, but were finally expelled by the superior force 
of the Agoneseah, or Five Nations. Whether this is literally true or 
not, it is well known that the Adirondacks resided in and occupied a 
part of this northern section of the State, and undoubtedly used a por- 
tion at least of the territory thus bounded as their beaver hunting 
grounds. This name is not so smooth as Aganuschioni, which has
