Jr. Horatio Alger 
Backwoods Boy Or The Boyhood and Manhood of Abraham Lincoln [EPUB ebook] 

Among our public men there is not one whose life can be studied with more interest and profit by American youth than that of Abraham Lincoln. It is not alone that, born in an humble cabin, he reached the highest position accessible to an American, but especially because in every position which he was called upon to fill, he did his duty as he understood it, and freely sacrificed personal ease and comfort in the service of the humblest. This is the story of Lincoln’s boyhood and manhood.
