"They have passed here, masters," he announced. "I find little threads hanging to the thorns; and the grass is trampled in places."

"We must proceed with caution," said Mori, restraining Nattie, who had already started. "Remember, Ralph has a number of men with him, and he is liable to ambuscade us."

"I will go on ahead," volunteered the giant porter, swinging his massive sword vindictively. "You follow slowly. If I see anything I will make the sound of a wild crow."

"Don't lose any time in your scouting," said Nattie, impatiently. "Confound them, they'll get away from us yet."

Leaving his horse in charge of one of the coolies, Sumo slipped through the brush and disappeared down one of the ravines. After looking to their weapons, the rest silently followed. They had barely traveled a hundred yards when the harsh cry of a wild crow came to their ears; then before the echoes had died away, the fierce clashing of steel thrilled the air.

"He has been attacked," shouted Nattie, putting his horse to the bushes. "Quick, we have them now!"

With the rest at his back, he dashed down a gentle slope into the head of the ravine. Passing a large clump of trees they came upon a most thrilling scene. Two hundred yards from the hill the valley narrowed to a space not wider than a city sidewalk.

The "gut" was formed by a huge mass of earth, which had fallen from the heights overhead. The bottom was evidently the dry bed of a mountain stream, and innumerable bowlders and jagged pieces of flint were scattered here and there, rendering walking difficult.

The scenery was an afterthought. That which instantly attracted the attention of Nattie and Mori was the figure of a native almost as large as Sumo standing at the beginning of the narrow passage. The fellow was armed with a sword, which he shook vindictively at the party.
