Walking farther than he intended, he found himself, almost before he was aware, crossing one of the numerous bridges that span the river. He was busy with thoughts of Jim, and how he could help him, and did not notice that two boys were following him stealthily. It was a complete surprise to him therefore when they rushed upon him, and, each seizing an arm, rendered him helpless.
"Hand over what money you've got, and be quick about it!" demanded one of the boys.
