PREFACE.

Garfield said, "No page of human history is so instructive and significant as the record of those early influences which develop the character and direct the lives of eminent men."

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."

Vincenzo wrote learnedly about music, and taught his boy to play on the lute and the organ; but he was poor and life was a struggle. However beneficial poverty may be in the development of character, most of us do not crave it for our children, so Vincenzo decided to place his son where he could earn a comfortable support. Music did not bring money. Galileo therefore should become a dealer in cloth; a necessity of life, rather than a luxury.

GALILEO GALILEI.

But the boy soon showed great skill in music, surpassing his father. He excelled in drawing and color, and could have become a noted artist. He loved poetry, and had a decided taste for mechanics, making
