In dealing with this perplexing subject. Mr. Lincoln kept in mind one of his favorite stories: the one on the Methodist Presiding Elder who was riding about his circuit during the spring freshets. A young and anxious companion asked how they should ever be able to cross the swollen waters of Fox River, which they were approaching, and the elder quieted him by saying that he made it the rule of his life never to cross Fox River until he came to it. The President, following this rule, did not immediately decide the question, but left it to be treated at the discretion of each commander. Under this theory some commanders admitted black people to their camps, while others refused to receive them. The curt formula of General Orders: "We are neither negro stealers nor negro catchers," was easily read to justify either course. Congress greatly advanced the problem, shortly after the battle of Bull Run, by passing a law which took away a master's right to his slave, when, with his consent, such slave was employed in service or labor hostile to the United States.
