But tiring at length of the long journeys, he became clerk in a village store at New Salem, Illinois. Many stories are told of Lincoln's honesty in his dealings with the people in this village store. It is said that on one occasion a woman, in making change, overpaid him the trifling sum of six cents. When Lincoln found out the mistake he walked three miles and back that night to give the woman her money. In less than a year the closing of this village store left him without employment, and after this he had a varied experience, first in a grocery store of his own, next as postmaster in New Salem, and then as a surveyor. ABRAHAM LINCOLN AND SLAVERY After many trials at various occupations, he decided at last to become a lawyer, and after being admitted to the bar, he opened an office at Springfield, Illinois. He succeeded well in his chosen profession, and also took a keen interest in the larger affairs of his community and State. In this wider field of action certain qualities of mind and heart greatly aided him. For, in spite of scant learning, he was a good public speaker and skilful debater, because he thought clearly and convinced those who heard him of his honesty and high purpose. Such a man is certain to win his way in the world. In due time he was elected to Congress, where his interest in various public questions, especially that of slavery, became much quickened. On this question his clear head and warm heart united in forming strong convictions that had great weight with the people. He continued to grow in political favor and, in 1858, received the nomination of the Republican party for the United States Senate. His opponent was Stephen A. Douglas, known as the "Little Giant," on account of his short stature and powerful eloquence as an orator. The debates between the two men, preceding the election, were followed with keen interest all over the country. Lincoln argued with great power against the spread of slavery into the new States, and although he lost the election, he won such favorable notice that two years later a greater honor came to him. In 1860, the Republican National Convention, which met at Chicago, nominated him as its candidate for President, and a few months later he was elected to that office. The agitation over slavery was growing more and more bitter, and when Lincoln was elected some of the Southern States threatened to go out of the Union. They claimed that it was their right to decide for themselves whether they should secede. On the other hand, the North declared that no State could secede without the consent of the other States.
