CHAPTER XI. — A COLLISION.

Although the two physicians were deeply interested in the question of toxicology they could not forget their situation and its perils¹. The craft had nearly completed its half mile to the mouth of the tributary² which it was intended to ascend³, when the polemen, pausing for a moment's rest, whispered that they heard the sound of paddles again.

"There they are!"

It was Jack⁴ Everson who uttered the exclamation⁵, loud enough for all to hear. He pointed⁶ down stream as he spoke⁷, and every one perceived the dreaded⁸ boat returning.

Although nearer at hand than before, it seemed to be following the course of the river, and there was hope that it would again pass without discovering the shrinking ones so near land.

When first observed the other boat was fifty yards out and not quite so far down stream. Moving against the current its progress was slower than before, but its advance was plainly perceptible. The craft of the white people had lost the momentum⁹ imparted by the poling, and was now controlled only by the current, which was so sluggish¹⁰ close to the land that the motion was hardly noticeable.

The hopes of our friends steadily¹¹ rose until the other boat was almost directly abreast¹². It would seem that if the occupants intended attacking they would have veered¹³ inward before this, but there could be no assurance so long as they remained visible.

Every one started when the gaunt, sloping figure suddenly became upright at the prow¹⁴ of the boat and stood motionless. He had ceased using the pole that he had been plying¹⁵ with so much vigor¹⁶. At the same moment the noise of the paddles ceased, proving that the men controlling them had also stopped work. What could it mean?

No one of the white people stirred or whispered. Could they have done so they would have checked the beating of their hearts through fear of being betrayed. Surely something had awakened¹⁷ the suspicion of the natives.

Suddenly some one spoke on board the craft. The voice was audible, but the doctor, who was a master of Hindoostanee, could not catch what was said. At the same instant a splash was heard, and the lank¹⁸ form bent¹⁹ over, as he pressed the long pole against the bottom of the river and resumed his slow walking toward the stern. The noise of paddles, too, was heard again. The craft had resumed its progress, and for an instant every one believed it was about to pass by. Then Jack Everson said:

"By heaven! they're coming for us!"

All saw that the boat was swinging around so as to head toward them.

"Into the cabin, quick!" commanded the doctor, and the women quickly scrambled²⁰ out of sight, while the men lay down, so as to screen their bodies as much as possible.

"It won't do to let them come too near," added the physician. "Try to make every shot tell."

As he spoke he took the best aim he could and fired. Jack Everson was but a moment behind him, and Anderson discharged his gun almost simultaneously²¹.
