"Now on, boys, on!" sung out the doctor, who saw what had occurred; and bringing our sticks down on our horses' backs, we dashed past the infuriated negroes, on whose heads Silva bestowed many a terrific whack with his stout stick, as they attempted to catch his rein. We were followed closely by the guide and our valiant ally, old Surley, at whom several blows were aimed, but he escaped them all, and at full gallop we pushed over the sandy plain, pursued by our black assailants. Happily they had no fire-arms, or we should have fared ill. When we had got beyond their reach we pulled up and congratulated ourselves on our escape, while old Surley came in for his due share of praise and thanks. He wagged his tail and opened his mouth, as if he were about to speak and say, "I only did my duty, masters; you feed me well, and treat me kindly, and I love you, and am ready to fight for you, and do you any other service in my power, as I hope to prove whenever I have the opportunity." It was very late when we got back to Lima, to the house of a merchant who had asked us to stay with him. He told us that the blacks who attacked us were, he had no doubt, emancipated slaves, who had always borne a very bad character. Had they been properly educated, and prepared for freedom, they might have turned out well; but those wretches are a melancholy example of what will be found to be the case in other countries where slavery still exists, should the slaves suddenly be made free, or should they rise and win their freedom for themselves. Unless they are carefully trained--taught to depend on their own exertions, and instructed in the pure truths of Christianity-- they will, when freed, sink into a state of sloth and wretchedness; or if they rise to obtain their own freedom, they will, very certainly, be guilty of the most dreadful murders and every kind of atrocity in carrying out their designs. I often have since thought of what our friend said, and have prayed that the people of the United States will make due preparation for enlightening those held so long in bondage. On the nature of that preparation it defends (I have often heard Captain Frankland say) whether their dear-bought liberty shall give joy and gladness, or poverty and misery.
