During the four years of his college life John Muir made his way by teaching school a part of each winter and doing farm-work summers. He sometimes cut down the expense of board to fifty cents a week by living on potatoes and mush, which he cooked for himself at the dormitory furnace. Pat, the janitor, would do anything for this young man who could make such wonderful things. Years afterward he pointed out his room to visitors and tried to describe the wonders it had contained. It had, indeed, looked like a branch of the college museum, with its numerous botanical and geological specimens and curious mechanical contrivances.
Although he spent four years at the State University, he did not take the regular course, but devoted himself chiefly to chemistry, physics, botany, and geology, which, he thought, would be most useful to him. Then, without graduating, he started out “on a glorious botanical and geological excursion which has lasted,” he said, in concluding the story of his early life, “for fifty years and is not yet completed.”
He journeyed afoot to Florida, sleeping on the ground wherever night found him. “I wish I knew where I was going,” he wrote to a friend who asked about his plans. “Only I know that I seem doomed to be ‘carried of the spirit into the wilderness.’”
Because he loved the whole fair earth and longed to know something of the story that its rocks and trees might tell, he wandered on and on. After going to Cuba, a siege of tropical fever, contracted by sleeping on swampy ground, caused him to give up for a time a cherished plan to make the acquaintance of the vegetation along the Amazon.
“Fate and flowers took me to California,” he said. He found there his true Florida (Land of Flowers), and he found, also, what became the passion of his life and his life work--the noble mountains, the great trees, and the marvelous Yosemite. Here he lived year after year, climbing the mountains, descending into the cañons, lovingly, patiently working to decipher the story of the rocks, and to make the wonder and beauty which thrilled his soul a heritage for mankind forever.
He lived for months at a time in the Yosemite Valley, whose marvels he knew in every mood of sunshine, moonlight, dawn, sunset, storm, and winter whiteness of frost and snow. He would wander for days on the heights without gun or any provisions except bread, tea, a tin cup, pocket-knife, and short-handled ax.
