The Lord of the Rings, pages 672-673:
Grey as a mouse,
Big as a house,
Nose like a snake,
I make the earth shake,
As I tramp through the grass;
Trees crack as I pass.
With horns in my mouth
I walk in the South,
Flapping big ears.
Beyond count of years
I stump round and round,
Never lie on the ground,
Not even to die.
Oliphaut am I
Biggest of all,
Huge, old, and tall.
If ever you'd met me
You wouldn't forget me,
If you never do,
You won't think I'm true;
But old Oliphaunt am I,
And I never lie.
The Lord of the Rings, pages 687-688:
"Ware! Ware!" cried Damrod to his companion. "May the Valar turn him
aside! Mumak! Mumak!"
To his astonishment, and terror, and lasting delight, Sam saw a vast shape
crash out of the trees and come careering down the slope. Big as a house,
much bigger than a house, it looked to him, a grey-clad moving hill. Fear
and wonder, maybe enlarged him in the hobbits eyes. But the Mumak of Harad
was indeed a beast of vast bulk, and the like of him does not walk now
in Middle-earth: his kin that live still now in latter days are but memories
of his girth and majesty. On he came, straight towards the watchers, and
then swerved aside in the nick of time, passing only a few yards away,
rocking the ground beneath their feet: his great legs like trees, enormous
sail-like ears spread out, long snout upraised like a huge serpent about
to strike, his small red eyes raging. His upturned hornlike tusks were
bound with bands of gold and dripped with blood. His trappings of scarlet
and gold flapped about him in wild tatters. The ruins of what seemed a
very war-tower lay upon his back, smashed in his furious passage through
the woods; and high upon his neck still desperately clung a tiny figure
- the body of a mighty warrior, a giant among the Swertings.
