ng the brush and raise a great uproar of shouting the war cries. Do
you understand?"

"I understand, O Tahara!"

"Then when the Arabs rush to attack you, meet them with a shower of
arrows and quietly climb part way up the cliffs. Leave the torches in
the ground to deceive the Arabs and as they charge upon that spot, you
can shoot at them from the cliffside with more arrows."

"I hear, Master, I obey!" said Kulki.

"Good! Make sure that every man knows what he is to do."

Dick turned to Raal and continued:

"You, Raal, take your brave Taharans down the cliff to the north of the
Arab camp. Be quiet and give no alarm. Then when the Gorols raise the
war cry and the Arabs rush to fight them off, follow with your Taharans
and attack the enemy from the rear. Use bows and arrows first; then
rush in with stone axes and flint knives. In a hand-to-hand fight,
their long guns will be useless."

"I hear, Master. I rejoice in a hand-to-hand battle."

"Good! I will be in a position to oversee the battle, for Dan and I
will climb down the cliff above the Big Spring, and when your Taharans
charge, I will join you."

Dan reminded his friend, "Be sure to tell them about the signal for
attack."

Dick replied. "You are right.--This is the signal. You, Kulki, when
you reach your position, will give a long call like the hyena. Raal
will answer with a wolf howl. When you hear the howl of the wolf, it
is the signal to open the battle."

"I hear, O Tahara."

"We obey, O Master."

The two chiefs saluted and withdrew to their troops and the climb down
the cliffs began, silently in the night.

Dick and Dan looked down over the edge of the cliffs and saw the camp
fires of the Arabs below them, with shadowy figures moving about or
squatting by the glowing coals.

Then the two boys began their slow difficult climb down the rocky face,
using every care to move quietly. A single rock dislodged and bouncing
down the cliffside would put the Arabs on guard and this must be a
surprise attack to be a successful one.

When Dick and Dan finally reached a ledge about a hundred feet above
the camp, they were only too glad to sit there and rest. The descent
of that steep slope in the dark was hard work; their hands were
scratched and bleeding and their muscles felt the strain.

"We will just sit here and take it easy for a while," said Dick.

"It is like being in a circus waiting for the show to begin," replied
Dan. "If onl
