有声读物: Boy Scouts on Lost Trail

Walter Upton again sets out with a group of boys on a great adventure in the North Woods, this time on foot. They've heard of a trail that had been used in the days of the settlers, and are seeking to locate and map it all the way to Canada. Their journey will test the skills they have, as well as learn new ones as they develop from boys to men, and learn to handle situations they never considered.
