Perhaps in the excitement of the moment the parent did not fully comprehend the danger of leaving his daughter alone in the jungle, even at so slight a distance and for so brief a time as he anticipated, with nothing but a revolver as a means of defence; but he and Jack Everson were eager to rush to the aid of their friends, and they hurried over the trail without even looking back at her.
The young man was slightly behind his companion and both broke into a loping trot. Each held his rifle in hand, on the alert to use it the instant the opportunity presented itself.
It will be borne in mind that the distance from the slight natural opening to the boat was short, and a few minutes sufficed for the two men to cover it; but a strange thing happened. The reports of firearms which had broken out with such suddenness ceased with the same abruptness, and the silence because of the contrast was tenfold more oppressive than before.
"What can that mean?" asked Jack, as his companion slackened his pace.
"It means that they are through!" replied the doctor, whose face was of deathly paleness. "My God! what have we escaped!"
"We shall soon know," replied Jack, catching the awful significance of the words; and then he added to himself:
"We may have escaped it, but for how long?"
A few rods further and they were at the side of the stream, and the boat loomed to view through the thick undergrowth and vegetation.
