Daniel Boone: The Pioneer of Kentucky [PDF ebook] 

The name of Daniel Boone is a conspicuous one in the annals of our country. And yet there are but few who are familiar with the events of his wonderful career, or who have formed a correct estimate of the character of the man. Many suppose that he was a rough, coarse backwoodsman, almost as savage as the bears he pursued in the chase, or the Indians whose terrors he so perseveringly braved. Instead of this, he was one of the most mild and unboastful of men. He was truly one of nature’s gentle men. This narrative reveals a state of society and habitudes of life during the founding of the Republic.
