Harriet Tubman

Apart from the rest of the children, on the top rail of a fence, holding tight on to the tall gate post, sat a little girl of perhaps thirteen years of age; darker than any of the others, and with a more decided woolliness in the hair; a pure unmitigated African. She was not so entirely in a state of nature as the rollers in the dust beneath her; but her only garment was a short woolen skirt, which was tied around her waist, and reached about to her knees.
She seemed a dazed and stupid child, and as her head hung upon her breast, she looked up with dull blood-shot eyes towards her young brothers and sisters, without seeming to see them. Bye and bye the eyes closed, and still clinging to the post, she slept. The other children looked up and said to each other, "Look at Hatt, she's done gone off agin!" Tired of their present play ground they trooped off in another direction, but the girl slept on heavily, never losing her hold on the post, or her seat on her perch.
Behold here, in the stupid little negro girl, the future deliverer of hundreds of her people; the spy and scout of the Union armies; the devoted hospital nurse; the protector of hunted fugitives; the eloquent speaker in public meetings; the cunning eluder of pursuing man-hunters; the heaven guided pioneer through dangers seen and unseen; in short, as she has well been called, "The Moses of her People."
