is barred by a huge rampart of moss-grown boulders, under whic 
the stream has to find its way, out of sight but not out of hearing. 
After a hidden passage of a hundred or two yards, it reappears, and 
descends for about half a mile to the main stream of Glencoe, 
through a narrow, precipitous ravine, the sides fringed with trees 
and clothed with a most luxu = nt vegetation of ferns and mosses,
