Public interest in the subject was more and more aroused, not only by the cases of cruelty and injustice which were forcibly brought to the attention of Northern communities, but also by the romantic and thrilling episodes of the escapes. To understand the attitude of the North toward fugitives, it is necessary to examine some of the different methods used by the fugitives in their flight. Perhaps a better point of view than that of the outside observer will be gained by placing ourselves in the position of the slave, and examining his motives for flight, the difficulties which he encountered at home, the manner in which he overcame them, and, finally, the various paths of escape then open to him, and the agencies which befriended him and forwarded him on his way. [Sidenote: Reasons for Escape.] =§ 64. Reasons for escape.=--First, why did the slave seek to escape? However unlike the attending circumstances, we find upon investigation that the negro's desire to run away may be traced to one of but three or four motives. Among the more intelligent slaves, who could comprehend the nature and injustice of their position, it often rose solely from the upspringing in their hearts of that love of freedom natural to all men. It is probable that in the greater number of cases this was the motive at the root of the matter. A fugitive, on being questioned at an Underground Railroad station as to his reasons for escape, replied that he had had a kind master, plenty to eat and to wear, but that notwithstanding this for many years he had been dissatisfied. He was thirsting for freedom.[216] Another said that his owner had always been considerate, and even indulgent to him. He left for no other reason than simply to gain his liberty.[217] A second reason, and that which perhaps most frequently led them to take the decisive step in this often long premeditated act, was the cruel treatment received from their masters. An owner upon one of the Southern plantations said his slaves usually ran away after they had been whipped, or something had occurred to make them angry.[218] A third and very effective cause was the fear of being sold South, where slave life, spent in toil under the merciless masters of the rice swamps and cotton fields, was seen on its darkest side. Such was the horror with which the slave regarded this change, that the threat of it was constantly used by owners as one of the surest means of reducing their rebellious slaves to submission. In the Virginia Slave Mother's Farewell to her Daughters who have been sold into Southern bondage, Whittier has well expressed their feelings.[219]
