Standing at the upper end of the one of the Happy Isles, one gets a splendid impression of the cascade effect of the waters, rushing madly down a steep rocky channel, with an irresistible, terrifying force.

Or it may be described in the graphic words of Thomson: With woods o'erhung, and shagg'd with mossy rocks, Whence on each side the gushing waters play, And down the rough cascade white dashing fall, Or gleam in lengthened vista through the trees.

Piche, Pisse, a cascade waterfall.

But when we came to the next cascading bit, though the mist had now lifted, we lightened the canoe by two men's avoir-dupois, that it might dance, and not blunder heavily, might seek the safe shallows, away from the dangerous bursts of mid-current, and choose passages where Cancut, with the setting-pole, could let it gently down.

We emerged from the birchen grove upon the river, below a brilliant cascading rapid.
