Having made this remark, he led the way in the direction the other Indian had taken.  He soon overtook him; but as darkness was increasing we had to proceed slowly, so as not to lose the trail, which I was utterly unable to perceive.  The banks here were of a low, marshy nature, so that there were few trees about up which the fugitive could have escaped.  I did not confidently expect to meet Mike on this occasion, for he, I thought, would have come along on his skates, whereas this person, the Indian said, was on foot.
