150 AT THE NORTH OF BEARCAMP WATER. 
by the moss beds through which it had filtered, 
poured in quivering folds over the rock. Stand¬

lowest incline, we could see four of these smooth 
ledge faces rising one behind another above us. 
Climbing to their top, we saw as many more still 
higher, and beyond them all, twin cascades 
gleamed through the trees, as they fell from a 
ledge in the middle of which a mass of black 
spruces and huge gray rocks seemed to form an 
island poised in the air between the two halves 
of the torrent. 
Nearly a thousand feet above this twin fall,

most despaired of further progress up the moun¬ 
tain, was a wall of gray rock suspended between 
the sky and the tree-tops. It was the last re¬ 
doubt of the impregnable Paugus. Was there 
a rift in its apparently solid face? Yes, I knew 
that there must be, because years before I had 
come down this ravine from the summit and 
had found no obstacle to gradual and easy de¬ 
scent. While passing the falls, we used the 
barometer to ascertain their approximate height, 
and found a difference of two hundred and fifty 
feet between the level of the pool at their foot 
and that of the stream above the twin cascades. 
The several inclines down which the water shot 
in rippling sheets were each fifty or sixty feet
