Pete shared his dread, but they both kept their thoughts to themselves as they swam on with strong, steady strokes, their light clothing of shirt and short drawers impeding them but slightly. Life from childhood on the seashore had conduced to making them expert swimmers; the swift stream helped them famously; and, keeping well away towards the middle to avoid the eddies near the shore, they went on steadily after the boat.
But this, in its light state, was being swept rapidly on, and had so good a start that for some time the swimmers did not seem to gain upon it in the least, and at last, as the distance still remained about the same, a feeling of despair began to attack them.
Pete saw the change in his fellow-swimmer’s countenance.
“Take it easy, Master Nic. Long ztroke and zlow. We could keep this up all day. On’y got to zwim steady: river does all the work.”
“We must swim faster, Pete, or we shall never reach the boat,” cried Nic.
“Nay, lad; if we zwim hard we shall get tired out, and lose ground then. Easy as you can. She may get closer in and be caught by zome of the branches.”
Nic said no more, but swam on, keeping his straining eyes fixed upon the ever-distant boat, till at last hope began to rise again, for the craft did happen to be taken by the eddy formed by a stream which joined the river, and directly after they saw it being driven towards one of the huge trees which dipped its pendent boughs far out in the water.
The feeling of excitement made Nic’s breath come thick and fast as he saw the boat brush against the leafage, pause for a few moments, and the young man was ready to utter a cry of joy, but it died out in a low groan, for the boat continued its progress, the twigs swept over it, and the power of the stream mastered. But it was caught again, and they saw it heel over a little, free itself, and then, swaying a little, it seemed to bound on faster than ever.
“Never mind, lad,” said Pete coolly; “it’ll catch again soon.”
Pete was right; the boat was nearer to the wall of verdure, and it once more seemed to be entangled in some boughs which dipped below the surface and hung there, while the swimmers reduced the distance between them and the boat forty or fifty yards. Then, with a swift gliding motion, it was off again.
