William felt as if he should drop down on the spot; but he controlled himself, and went and asked his master to go back to the office. It was a terrible fright. As Mr. Johnson stepped out he whispered, in great agitation, "O William, is it possible we shall have to go back to Slavery, after all we have gone through?" It was very hard to satisfy the station-master. He said if a man carried off a slave that did not belong to him, and the rightful owner could prove that he escaped on that road, they would be obliged to pay for the slave. Mr. Johnson kept up a calm appearance, though his heart was in his throat. "I bought tickets at Charleston to pass us through to Philadelphia," said he; "therefore you have no right to detain us here." "Right or no right, we shall not let you go," replied the man. Some of the spectators sympathized with the rich young Southerner, and said it was a pity to detain him when he was so unwell. While the man hesitated, the bell rang for the cars to start, and the fugitives were in an agony. "I don't know what to do," said the man. "It all seems to be right; and as the gentleman is so unwell, it is a hard case for him to be stopped on the way. Clerk, run and tell the conductor to let this gentleman and his slave pass." They had scarcely time to scramble into the cars, before the train started. It was eight o'clock in the evening, and they expected to arrive in Philadelphia early the next morning. They did not know that on the way the passengers would have to leave the cars and cross the river Susquehanna in a ferry-boat. They had slept very little for several nights before they left Georgia, and they had been travelling day and night for four days. William, overcome with fatigue, and feeling that their greatest dangers were now over, fell sound asleep on a heap of baggage. When they arrived at the ferry, it was cold, dark, and rainy; and for the first time during their hazardous journey the invalid found no faithful servant at hand when the cars stopped. He was in great distress, fearing that William had been arrested or kidnapped. He anxiously inquired of the passengers whether they had seen his boy. There were a good many Northerners on board, and, supposing his slave had run away, they rather enjoyed his perplexity. One gruffly replied, "I am no slave-hunter." Another smiled as he said, "I guess he is in Philadelphia before now."
