Fragment: As some vast Tropic tree, itself a wood

As some vast Tropic tree, itself a wood,
That crests its head with clouds, beneath the flood
Feeds its deep roots, and with the bulging flank
Of its wide base controls the fronting bank--
(By the slant current's pressure scoop'd away
The fronting bank becomes a foam-piled bay)
High in the Fork the uncouth Idol knits
His channel'd brow; low murmurs stir by fits
And dark below the horrid Faquir sits--
An Horror from its broad Head's branching wreath
Broods o'er the rude Idolatry beneath--
