re
leaving any of these coverts, he anxiously scrutinised the horizon
towards the north, and once or twice requested the boys to climb the
highest tree they could find, and report whether anything was visible in
the distance.
His strength and confidence alike seemed to improve as the day advanced.
About twelve o'clock they made what was to be their long halt, in a
patch of scrub which sprung apparently out of the barren sand, though
there was neither spring nor pond anywhere to be seen, nor even any
appearance of moisture. They had progressed about four miles in
something less than five hours, and were now, Omatoko told them, hardly
a mile from their destination. He pointed it out indeed in the
distance--a rocky eminence, with a patch of trees and grass lying close
to it. But the party had not been seated for ten minutes, and were
still engaged in devouring the melons they had brought with them, when
their guide again rose and advised their immediately resuming their
journey.
"What, go on at once?" exclaimed Gilbert. "Why, what is that for? I am
just beginning to get cool--that is, as cool as ever I expect to be
again. If we have only a mile to go, we had surely better walk it in
the cool of the evening than under this broiling sun."
"Must not wait," said Omatoko. "Storm come soon--not able go at all."
"The storm! Do you see any signs of one, doctor? I don't."
"Yes, I see signs; but I own I should not have thought it would break
out for some hours. But the changes of the atmosphere are wonderfully
rapid in this country, and I have no doubt the Hottentot is right. Will
it be on us in another hour, Omatoko?"
"Perhaps half an hour, perhaps three-quarters," was the answer.
"Half an hour! We must be off this minute, and move as fast as we can.
Here, Frank, Ernest--hoist Omatoko on to my shoulders; I can carry him
for a quarter of a mile, any way, and that will be ten minutes saved."
"And I'll take him as far as I can, when you've done with him," added
Warley, "and so, I doubt not, will the others. Lift him up. There,
that's right. Now step out as fast as we can."
By the time that the doctor's "quarter of a mile," as it was called--
though it was in reality nearly twice that distance--was completed, the
signs of the approaching hurricane began to gather so fast, that even
the most unobservant must have perceived them. The clouds came rapidly
up, and gradually hid the rich blue of the sky. T
