possibilities that the fleet-footed Gallas would overtake the
heavily-burdened camels.

It was no time for conversation or explanation. A fervent "Thank God!"
burst from Colonel Carrington's lips as he realized that he had fallen
into the hands of friends, while Sir Arthur, feebly beginning to
comprehend what had happened, ejaculated several times, "Bless my soul,"
as he clung with might and main to the Greek's waist.

Faster and faster they sped over the plain, until the tumult behind them
was lost in the muffled tramp of the camels' hoofs. They rode side by
side, with arms ready for instant use, but no foe appeared in front or
behind, and at last, with a glad cry, Canaris pointed to the distant
gleam of the Abyssinian camp.

"We are safe now," exclaimed Guy. "The Gallas feared to pursue us any
further lest their anticipated attack on the Abyssinians should be
spoiled."

"Yes," replied Canaris, "either that or they have circled round, hoping
to cut us off at yonder gap in the mountains where the road breaks
through to the coast. And now the rock must be close by. Ha! What does
that mean?"

Bang! went a rifle shot directly ahead, and a brief red flash pierced
the gloom.

"It is Forbes!" cried Chutney. "He is in danger. Quick, quick, to the

A loud shout followed closely on the heels of the report, and

An answering hail came distinctly back, followed immediately by a second
shot.

The agony of suspense was brief. A moment later the rock loomed into

cavern.

"Oh, you've come back safe?" exclaimed Melton coolly, as he came forward
with a smoking rifle in his hand. "I've had a brush with a party of
Abyssinians. They were hunting their camels, I suppose, and took me by
surprise. I dropped one of the rascals, and----Look out! There they are
again."

All dodged to the ground as a shower of spears fell about the rock. With
a hollow groan one of the camels dropped heavily over, pierced in the
throat by a short spear, and his huge bulk formed a natural barrier
before the cavern. Melton's rifle cracked sharply and a howl of pain
attested the accuracy of his aim.

"Into the cavern, all of you," cried Guy. "The Abyssinians are coming in
force; the firing has attracted them to the spot."

Already a shadowy mass was vi
