Boy Scouts co-founder and avid outdoorsman "Uncle Dan" Beard researched the secret languages of trappers, hobos, steamer pilots, and Indian tribes to compile this comprehensive resource of pictographs and other encoded communication symbols. First published nearly a century ago, this practical reference provides scouts and other lovers of the outdoors with an ever-useful guide to following trails and interpreting their surroundings. AUTHOR: Known as "Uncle Dan" to his friends, Daniel Carter Beard (1850–1941) was a famed author, illustrator, and social champion. Inspired by the rugged traditions of the American frontier, Beard founded the Sons of Daniel Boone in 1905. Five years later, he merged the organisation with the newly formed Boy Scouts of America.
