Sometimes when hard pressed by pursuers she would take a train southward with her companions; she knew that no one would suspect fugitives travelling in that direction. Harriet was a well-known visitor at the offices of the anti-slavery societies in Philadelphia and New York, and at first she seems to have been content if her protégés arrived safely among friends in either of these cities; but after she comprehended the Fugitive Slave Law she preferred to accompany them all the way to Canada. "I wouldn't," she said, "trust Uncle Sam wid my people no longer."[546] She knew the need of discipline in effecting her rough, overland marches, and she therefore required strict obedience of her followers. The discouragement of an individual could not be permitted to endanger the liberty, and safety of the whole party; accordingly she sometimes strengthened the fainting heart by threatening to use her revolver, and declaring, "Dead niggers tell no tales, you go on or die." She was not less lenient with herself. The safety of her companions was her chief concern; she would not allow her labors to be lightened by any course likely to increase the chances of their discovery. On one occasion, while leading a company, she experienced a feeling that danger was near; unhesitatingly she decided to ford a river near by, because she must do so to be safe. Her followers were afraid to cross, but Harriet, despite the severity of the weather (the month was March), and her ignorance of the depth of the stream, walked resolutely into the water and led the way to the opposite shore. It was found that officers were lying in wait for the party on the route first intended. [546] Mrs. Bradford, _Harriet the Moses of Her People_, p. 39. Like many of her race Harriet was a thorough-going mystic. The Quaker, Thomas Garrett, said of her: "... I never met with any person, of any color, who had more confidence in the voice of God, as spoken to her soul. She has frequently told me that she talked with God, and he talked with her, every day of her life, and she has declared to me that she felt no more fear of being arrested by her former master, or any other person, when in his immediate neighborhood, than she did in the State of New York, or Canada, for she said she never ventured only where God sent her. Her faith in the Supreme Power truly was great."[547] This faith never deserted her in her times of peril. She explained her many deliverances as Harriet Beecher Stowe accounted for the power and effect of _Uncle Tom's Cabin_. She insisted it was all God's doing. "Jes so long as he wanted to use me," said Mrs. Tubman, "he would take keer of me, an' when he didn't want me no longer, I was ready to go. I always tole him, I'm gwine to hole stiddy on to you, an' you've got to see me trou."[548] [547] Mrs. Bradford, _Harriet the Moses of Her People_, pp. 83, 84. [548] _Ibid._, p. 61.
