"Huh!" grunted Jacinto, and then he called to the paddlers to increase their strokes.
The journey up the river was not very eventful. Many alligators were seen, and Tom and Ned shot several with the electric rifle. Toward the close of the third day's travel there was a cry from one of the rear boats, and an alarm of a man having fallen overboard was given.
Tom turned in time to see the poor fellow's struggles, and at the same time there was a swirl in the water and a black object shot forward.
"An alligator is after him!" yelled Ned.
"I see," observed Tom calmly. "Hand me the rifle, Ned."
Tom took quick aim and pulled the trigger. The explosive electric bullet went true to its mark, and the great animal turned over in a death struggle. But the river was filled with them, and no sooner had the one nearest the unfortunate Indian been disposed of than another made a dash for the man.
There was a wild scream of agony and then a dark arm shot up above the red foam. The waters seethed and bubbled as the alligators fought under it for possession of the paddler. Tom fired bullet after bullet from his wonderful rifle into the spot, but though he killed some of the alligators this did not save the man's life. His body was not seen again, though search was made for it.
The accident cast a little damper over the party, and there was a feeling of gloom among the Indians. Professor Bumper announced that he would see to it that the man's family did not want, and this seemed to give general satisfaction, especially to a brother who was with the party.
Aside from being caught in a drenching storm and one or two minor accidents, nothing else of moment marked the remainder of the river journey, and at the end of the third day the canoes pulled to shore and a night camp was made.
"But where are the mules we are to use in traveling to-morrow?" asked the professor of Jacinto.
