Passing through the suburbs of the city one day, her attention was arrested by the chime of youthful voices. Seeing that the music proceeded from some little beggar-girls, who were sitting in the sun beside the fence and singing a Sabbath school hymn, she inquired of them what they were doing, when the following dialogue occurred: "We were cold, ma'am, and are getting warm in the sun." "Where do you live?" "In Twentieth street, ma'am." "Why have you come so far away from your homes?" "To get some food and some things to make a fire." "Why were you singing?" "To praise God: we go to the Sunday school, and our teacher says if we are good children God will never let us want." Pleased with the modest and artless answers to her questions, the good woman took them across the street, procured each of them a loaf of bread, gave them some pious counsel, and left them with smiles on their faces and gratitude in their hearts. Mrs. Prior frequently visited the city prison, and on occasion[78] went to Sing Sing. She made a record of her visit to the latter place, from which we make an extract: "In visiting the female convicts at their cells on Sabbath morning, after Sabbath school, which, under the customary regulations, we were permitted to do, we found nearly all employed in reading their Bibles. We conversed with them respecting the welfare of their souls, and as we knelt with them at the throne of grace, they on one side of the grated door and we on the other, we felt that He who healed a Mary Magdalene, is still the same compassionate Saviour, and our faith, we trust, apprehended him as the atoning sacrifice, who bore our sins in his own body on the tree, and opened a way for the salvation of even the chief of sinners." [78] June, 1840. Being on an errand of mercy in G---- street one day, she stepped into a house of infamy to leave a certain tract. As soon as she had entered and made known her mission, the door was closed and locked by one of the female inmates, who told her that she was their prisoner. "For a moment," writes Mrs. Prior, in her journal, "my heart was tremulous; I said nothing till the risings of fear were quelled, and then replied pleasantly, 'Well, if I'm a prisoner, I shall pray here, and would sing praises to God if I were not so hoarse. Yes, bless the Lord! his presence can make me happy here or any where, and you can have no power to harm me unless he gives it. This is a dreadful place, to be sure, but it is not so bad as hell; for there, there is no hope. The smoke of their torment ascendeth up for ever and ever! What a mercy that we are not all there! what compassion in the blessed Jesus that he spares us, when our sins are every day so great.' I talked to them in this manner till they were glad to open the door as a signal for my release."
