equally logical to opposite sorts of minds. Ben Butler, in Virginia, quickly declared slave property contraband of war, and put the fugitives to work; while Fremont, in Missouri, declared the slaves free under martial law. Butler's action was approved, but Fremont's was hastily countermanded, and his successor, Halleck, saw things differently. "Hereafter," he commanded, "no slaves should be allowed to come into your lines at all; if any come without your knowledge, when owners call for them deliver them." Such a policy was difficult to enforce; some of the black refugees declared themselves freemen, others showed that their masters had deserted them, and still others were captured with forts and plantations. Evidently, too, slaves were a source of strength to the Confederacy, and were being used as laborers and producers. "They constitute a military resource," wrote Secretary Cameron, late in 1861; "and being such, that they should not be turned over to the enemy is too plain to discuss." So gradually the tone of the army chiefs changed; Congress forbade the rendition of fugitives, and Butler's "contrabands" were welcomed as military laborers. This complicated rather than solved the problem, for now the scattering fugitives became a steady stream, which flowed faster as the armies marched.
Then the long-headed man with care-chiselled face who sat in the White House saw the inevitable, and emancipated the slaves of rebels on New Year's, 1863. A month later Congress called earnestly for the Negro soldiers whom the act of July, 1862, had half grudgingly allowed to enlist. Thus the barriers were
