loating swiftly away down the rapids. He ran into the water and
seized the boat, which was then beginning also to go away. He called
upon the boys to help him pull it up and pour the water out. He then
lanched it again with all speed, seized one of the poles, clambered
into it, and pushed off into the swiftest part of the current, and
away he went after his cap.

He resorted to this desperate measure, because he was greatly alarmed
at the idea of going home without his cap. It would have certainly
insured his detection, and, as he supposed, a double punishment. He
now was as eager to go down the rapids as he had before been to escape
them. His only care was to keep his boat head down, so that if he
should encounter any snag or rock he might not be thrown broadside on.
He kept a good lookout too ahead. The boat shot through the water like
an arrow, and was soon clear of the rapids in the comparatively still

Marco contrived to paddle with his pole, so as to overtake the cap and

boat as high as he could, and went back to seek the other boys. He
concluded that it was time to go home. His conscience now began to

pleasure had failed. His clothes were wet and uncomfortable. His mind
was anxious and unhappy. With a heavy heart he began to retrace his
steps, sure of detection when he reached home, and of punishment. He
did not, however, dread the punishment so much as the just displeasure
which his cousin would manifest, and the evidence of the pain which he
knew his cousin would suffer, when he came to learn how his pupil had
betrayed the confidence which had been reposed in him. Before he set
out for home, however, he took off such of his clothes as were most
wet, and wrung out the water as well as he could, and then put them on
again.

When he drew near to the house, he expected to see his uncle still at
work, but he was not there. Marco reconnoitered the place carefully,
and then went into the office. His uncle was not in the office. He
passed through into the study. He was afraid that Forester would be
there, but, to his surprise and joy, he was not, and there was no sign
that he had been there since the morning. Marco looked at the watch,
and found that it was only about half-past eleven. So he took down
a volume of the Encyclopedia and began to rea
