These sketches show how young men have overcome difficulties, sometimes poverty, sometimes illness; how they have made failures before finding their true vocation. They show the results of energy, perseverance, and untiring devotion; how a cheerful face and a hopeful spirit like Agassiz's, or a gentle and kindly nature like Darwin's, can win its way against opposition.
A sketch of Benjamin Franklin, which otherwise would have a place in this volume, will be found in "Famous American Statesmen"; also one of Michael Faraday, in "Poor Boys Who Became Famous."
