A Thousand-Mile Walk to the Gulf

 “John Muir, Earth-planet, Universe.”—These words are written on the inside cover of the notebook from which the contents of this volume have been taken. They reflect the mood in which the late author and explorer undertook his thousand-mile walk to the Gulf of Mexico a half-century ago. No less does this refreshingly cosmopolitan address, which might have startled any finder of the book, reveal the temper and the comprehensiveness of Mr. Muir’s mind. He never was and never could be a parochial student of nature.
