A few minutes later an open space appeared in front of the boat. It was the month of the tributary flowing into the Ganges from the left or north, and was more than a hundred yards across. Since it was necessary to stem the current in order to take advantage of this refuge, the doctor contemplated it with misgiving, for the work of poling it up stream promised to be laborious. He had not forgotten his original plan of abandoning the boat and striking across the country on foot, taking advantage of the less-frequented roads and paths that were well known to him. He was relieved, however, to find the flow so languid that it was easy to make headway against it.

"I have never followed this stream far," he remarked, "and, therefore, have less knowledge of it than the rest of the country, but my impression is that it cannot serve us long."

"It will be time enough to leave the boat and take to the woods when we can go no further," said Jack Everson; "but we cannot get away from the main stream too soon."

This was self-evident. It was not likely that the natives after their decisive repulse would abandon their purpose of massacring the party, but they would be more guarded in what they did and probably secure reinforcements, an easy thing to do when the sanguinary wretches everywhere were thirsting for victims.

Jack had seized one of the poles, and he and young Wharton plied them with so much sturdiness that the heavy craft made better progress than at any time since it was used as a vehicle of safety. The course of the tributary was winding, and our friends had not gone far when they were shut out from the sight of any persons passing up and down the main river, even if close to the northern bank.

Would the natives suspect the course taken by the whites? That was the all-important question that must soon be answered. After searching up and down the Ganges without success, it was likely they would penetrate the stratagem and follow them, in which event the fugitives would be in a critical situation, since the straightness of the stream and the wooded shores would place them at much greater disadvantage than if they remained upon the Ganges.

When the boat had ascended the tributary for perhaps an eighth of a mile it was deemed safe to lessen the work of poling. Careful listening failed to detect any sound of pursuit, and there was ground for hoping that their enemies neither knew nor suspected what had been done.

Several facts had become apparent. The densely wooded shores offered excellent concealment. By running the boat beneath the dense branches and among the heavy vegetation the keenest-eyed Asiatics might pass up or down stream almost within arm's length without suspecting its presence. But the tributary had perceptibly narrowed and its current was swifter than at the mouth. All this pointed to the truth of what Dr. Marlowe suspected—the stream could not serve them much further.

The night was now so far advanced that the women took the advice of their friends and withdrew to the cabin for slumber. Their quarters were cramped, but they made themselves fairly comfortable. The night was cooler than the day, but only sufficiently so to be pleasant. It was not deemed probable that anything would be seen of their enemies before the morrow, and perhaps not even then.

Dr. Marlowe insisted upon taking his turn in poling, but since there were four vigorous men without him, they would not consent. When two had toiled for an hour or more, they gave way to the other couple, and the progress thus continued without interruption, while the time slowly dragged along. The resting spells gave each the opportunity for sleep, thus husbanding their vigor for the morrow. Finding that there was nothing to which he could turn his hand, the physician reclined at the bow and soon joined the others in dreamland.

It was probably one o'clock when Jack Everson, who had been sleeping for nearly an hour, was awakened by a gentle shaking of his shoulder. Opening his eyes and looking up he saw Wharton bending over him.

"All right," remarked the American; "I'm ready for my turn," and he rose, yawning, to his feet.

"I think we had better rest until morning."

"Why?"

"The current has become so rapid that it is hard to make progress; this stream can't be of much further use to us."

It needed but a glance around in the gloom to see that it was as his friend had declared. The boat was so close to the left-hand shore that it was held motionless by Anderson at the bow, who gripped an overhanging branch, with one hand. The water rippled around the front of the craft, and when Jack dipped the end of one of the poles into the current it swept downward at a rate that astonished him.

"I esteem your advice good," he said, "but it will not do to leave the boat in sight."

With the help of the limbs and the use of the poles it was easy to force the craft under the bank, where it was screened from observation. Then it was secured in place against drifting and all work for the time was over.

Wharton and Jack Everson were the only persons awake. The women had been sleeping for several hours, while Anderson and Turner had long since joined the venerable doctor in the realms of unconsciousness. The two young men sat down where they could speak in low tones without being overheard.

"It won't do for all of us to sleep at the same time," remarked Jack; "the scoundrels may be creeping up stream after us."

"That is hardly possible; I am sure that for the present we are as safe as if in the heart of London."

"I cannot believe as you do; since I have just enjoyed an hour's sleep I will act as sentinel until daybreak. I can easily keep awake for the few hours that remain."

"As you think best, though I am sure it is an unnecessary precaution."

"We must not forget that there are perils from the jungle as well as from the river. There is no saying what wild beast may pay us a visit."

Inasmuch as Jack could not be dissuaded from his purpose, and Wharton began to suspect his friend was half right, the question was decided. Wharton stretched out on the deck, falling asleep almost immediately, and Jack thus found himself the only one with his senses at command and with the safety of the others dependent upon him.

He took his place near the cabin, where the women were slumbering, with his breechloader in hand. He was never more wide awake and was sure he would remain so for hours to come. Wharton had offered to divide the duty with him in acting as sentinel, but our hero preferred to keep the matter in his own hands. He was sure his friend did not realize the full peril of their situation.

The stillness was broken only by the peculiar cries in the jungle, which it may be said were never wholly silent. First on the right, then on the left, then from the front, and again from different points on both sides of the stream he heard the sounds, some faint and far away, with others alarmingly close. The hoarse snarl of the tiger, the finer cry of the leopard, the squawking of night birds, with other noises that he could not identify, were continually in the air. Had they been heard for the first time he would have been in a tremor of fear and nervousness; but man soon becomes accustomed to danger, and the nearest must come still nearer to cause his pulse an additional throb.
