They were then taken to Mr. Ellis Gray Loring's home. Here William showed a most honorable spirit. When he found Mr. Loring was not at home he would not remain, saying, "I am subjecting him to a heavy fine and imprisonment, and I must go at once to look for some other shelter." His pursuers, who had come from Georgia, were staying at the United States Hotel. The knowledge of their object was soon spread abroad, and they dared not go into the streets for fear of a mob. Handbills, calling attention to them, were placed everywhere, and cries of "Slave hunters! there go the slave hunters!" were heard on all sides. At last, they were absolutely compelled to leave the city. William and Ellen no longer felt safe, and therefore went to England, where the remainder of their life was spent in peace.[235] [Sidenote: The Underground Railroad.] =§ 70. Underground Railroad.=--From the preceding sketch of the conditions of escape, it is plain that no such numbers as are known to have fled could possibly have escaped from their masters' power had they depended solely upon their own exertions. From the beginning of the antislavery agitation, about 1830, and especially near 1850, a mysterious organization made it a business to receive, forward, conceal, and protect fugitives. To that organization the name of "Underground Railroad" was given, and the many methods used by those connected with it can best be given under a more elaborate description of the system. =§ 71. Rise and growth of the system.=--The first efforts toward any systematic organization for the aid and protection of fugitive slaves are found among the Quakers in Pennsylvania. The great number of cases of kidnapping which occurred in this State after the passage of the law of 1793, by their injustice roused people to action in behalf of the free blacks; and, their sympathies once enlisted for the colored race, it was but a step to the aid of the fugitive negroes.[236] From this time, as the number of runaways increased, new agencies were constantly being established, until from the slave States to Canada a perfect chain of stations was arranged, not more than one day's journey apart.[237] The system is said to have extended from Kentucky and Virginia across Ohio, and from Maryland, through Pennsylvania and New York, to New England and Canada.[238] As negroes began to disappear, and their masters found themselves unable to trace them farther than certain towns in Pennsylvania, they said, in bewilderment, "There must be an Underground Railroad somewhere," and this expression, suiting the popular fancy, became the general name by which the whole system was known.[239] [Sidenote: Operations "Underground."]
