The evidence

• “He supplemented his common school education by a course of study at Wesleyan Seminary, Readfield, Me., and at the age of eighteen years taught a public school in his state. In 1844 he became an apprentice in the carpenter's and builder's trade and followed that occupation some sixteen years. At the age of twenty-five, in 1850, he turned westward, landing at Milwaukee, Wis., with little capital other than his native energy, firm purpose, dauntless courage and determination.”
