The Victoria Falls

So hushed, so hot, the broad Zambesi lies
Above the Falls, and on her weedy isles
Swing antic monkeys swarm malignant flies,
And seeming-lazy lurk long crocodiles.
But somewhere down the river does the hush
Become a sibilance that hints a sigh,
A murmur, mounting as the currents rush
Faster, and while the murmur is a cry
The cry becomes a shout, the shout a thunder
Until the whole Zambesi waters pour
Into the earth’s side, agitating under
Infinite spray mists, pounding the world’s floor.
Wrapped in this liquid turmoil who can say
Which is the mighty echo, which the spray?
