e glare was almost blinding wherever the rocks were crystalline
and white.

"I say, is that a cloud?" said Jack Penny, drawing our attention to a
fleecy mass that could be seen rising between a couple of masses of
rock.

"Yes!" cried the doctor eagerly, as he shaded his eyes from the sun's
glare; "a cloud of spray. The falls are there!"

"Or is it the wind you can see in the trees?" I said, with a look at
Jack Penny.

"Get out!" retorted that gentleman. "I didn't say I was sure, and
doctor isn't sure now."

"No, not sure, Penny," he said; "but I think I can take you to where
water is coming down."

We felt no temptation to go on then, and willingly followed our guides,
who pointed out a huge mass of overhanging rock right in the side of the
ravine, and here we gladly halted, in the comparatively cool shade, to
sit and partake of some of the buffalo strips, my eyes wandering
dreamily to right and left along the narrow valley so filled with
stones.

I was roused from my thoughts about the strangeness of the place we were
in and the absence of trees and thick bush by the doctor proposing a bit
of a look round.

"We are getting up among the mountains, Joe," he said; "and this means
more difficult travelling, but at the same time a healthier region and
less heat."

"Oh, doctor!" I said, wiping my forehead.

"Why, it couldn't be any hotter than it is out there!" said Jack.

"Come with us, then, and let's see if we can find a fresh way out.
Perhaps we may hit upon a pass to the open country beyond. At all
events let's go and see the falls."

We took our guns, leaving all heavy things with the blacks, who were
settling themselves for a sleep.

The sun's heat almost made me giddy for the first hundred yards, and
either my eyes deceived me or Jack Penny's long body wavered and shook.

But we trudged laboriously on over and among masses of rock, that seemed
to be nearly alive with lizards basking in the sun, their curious coats
of green and grey and umber-brown glistening in the bright sunshine, and
looking in some cases as if they were covered with frosted metal as they
lay motionless upon the pieces of weatherworn stone.

Some raised their heads to look at us, and remained motionless if we
stopped to watch them, others scuffled rapidly away at the faintest
sound, giving us just a glimpse of a quivering tail as its owner
disappeared down a crevice almost by magic.

"Don't! don't fire!" cried the doctor,
