"No, no, my dear lad," said the doctor; "I was only joking. It is your task."
"But come too," cried Harry.
"There will be plenty in the boat without me. Off with you."
Harry looked unwilling to stir, but the doctor seized him by the shoulders and hurried him along, and the next minute they were being paddled towards the floating reptile, the men managing so that the boys could have a thrust in turn, the Prince as they passed along one side, Harry on their return on the other.
But the thrusts did not follow one another quickly, for the deep plunging in of the spear by Phra seemed to act like a reviver, although it was delivered about where the lad believed the heart to be.
In an instant the great reptile had flung itself over and began lashing the water with its tail.
"Take care!" shouted Mr. Kenyon from the landing-stage. But the warning was needless, for a sharp stroke from the oars sent the boat well out of reach, the rowers changing their positions and sending it backward in pursuit, as the crocodile began once more to swim up stream, at a pretty good rate at first, then slower and slower, leaving the water stained with its blood as it went on.
It managed to make its way, though, quite a hundred yards above the bungalow before its tail ceased its wavy, fish-like motion. Then there was a struggle and a little splashing, and once more it turned over upon its back.
"Your turn now," cried Phra excitedly. "I must have missed its heart.
You stab it there this time."
"Want the doctor here to tell me where it is," said Harry, as he stood up with his spear poised ready to strike when within reach.
