a shade of green. Other minerals of more common occur- 
rence, as garnet and black tourmaline, were observed here. 
Plumbago.—This mineral, of singular beauty, occurs near 
Ticonderoga, both massive and disseminated, in brilliant 
plates, in a large grained crystalized lime stone. It has been 
mistaken for molybdena, a circumstance which, a few years 
ago, was common in this country. This locality we did 
not visit, nor the celebrated one of Roger’s Rock,* where 
the cocolite is found. 
Magnetic Iron of Crown Point—We were not able to 
visit this place, but we saw them working the magnetic 
iron, from its vicinity, in the forges at Ticonderoga. ‘This 
iron ore is both rich and beautiful in its kind ; its struc- 
ture is granular and almost crystaline ; it has a brilliant 
black colour, and contains a yellowish imbedded min- 
eral scarcely visible without a glass; it resembles cocolite, 
but is too soft, and at present we are not willing to give ita 
name. 
Mountains of Lake George.—There can be no doubt that, 
whenever they are thoroughly explored, they will abundantly 
reward the geologist and mineralogist. We, however, saw 
them only as picturesque objects; as such, they are certain- 
ly very fine. Particularly as we proceed north from the 
Tongue Mountain, which is twelve miles from Caldwell. 
For twenty miles beyond this, on the way to Ticonderoga, 
the scenery combines, in an uncommon degree, both rich- 
ness and grandeur. ‘The mountains are all primitive: they 
form a double barrier, between which the lake, scarcely a 
mile wide, but occasionally expanding into large bays, winds 
its way. They are steep and precipitous to the very wa- 
ter’s edge : they are still clothed with grand trees, and pos- 
sessed by wild animals—deer, rattle-snakes, and bears. 
They give, in some places, the most distinct and astonish- 
ing echoes, returning every flexion of the voice with the 
most faithful response. We saw them hung with the sol- 
emn drapery of thunder clouds, dashed by squalls of wind 
and rain, and soon after decorated with rainbows, whose
