As far as energy and talent are concerned, I should not hesitate to say that in her own sphere Mum Bett "had no superior nor equal;" and the same may be said about the quality of fidelity. I know of a slave in Louisiana who picked up a parcel containing 10,000 dollars, and returned it, with much trouble, to its owner. I know of a slave in South Carolina, belonging to a physician, who drives his master's gig, and has made a wonderful use of what he sees in the course of his morning's duty. While waiting for his master at the doors of patients, this slave occupied himself with copying in the sandy soil the letters he saw on signs. When he believed he had caught the method, he begged a slate, or paper and pencil, and brought home his copies, coaxing the boys of the family to tell him the names of the letters. He then put them together, and thus learned to read and write, without any further help whatever. Having once discovered his own power of doing and learning, he went on in the only direction which seemed open to him. He turned his attention to mechanism, and makes miniature violins and pianos of surprising completeness, but no use. Here he will most likely stop; for there is no probability of his ever ceasing to be a slave, or having opportunity to turn to practical account a degree of energy, patience, and skill which, in happier circumstances, might have been the instruments of great deeds.

The energies of slaves sometimes take a direction which their masters contrive to render profitable, when they take to religion as a pursuit. The universal, unquenchable reverence for religion in the human mind is taken advantage of when the imagination of the slave has been turned into the channel of superstition. It is a fact, that in the newspapers of New-Orleans may be seen an advertisement now and then of a lot of "pious negroes." Such "pious negroes" are convenient on a plantation where the treatment is not particularly mild; as they consider nonresistance a Christian duty, and are able to inspire a wonderful degree of patience into their fellow-sufferers.

The vigour which negroes show when their destiny is fairly placed in their own hands, is an answer to all arguments about their helplessness drawn from their dulness in a state of bondage. A highly satisfactory experiment upon the will, judgment, and talents of a large body of slaves was made a few years ago by a relative of Chief-justice Marshall. This gentleman and his family had attached their negroes to them by a long course of judicious kindness. At length an estate at some distance was left to the gentleman, and he saw, with much regret, that it was his duty to leave the plantation on which he was living. He could not bear the idea of turning over his people to the tender mercies or unproved judgment of a stranger overseer. He called his negroes together, told them the case, and asked whether they thought they could manage the estate themselves. If they were willing to undertake the task, they must choose an overseer from among themselves, provide comfortably for their own wants, and remit him the surplus of the profits. The negroes were full of grief at losing the family, but willing to try what they could do. They had an election for overseer, and chose the man their master would have pointed out; decidedly the strongest head on the estate. All being arranged, the master left them, with a parting charge to keep their festivals, and take their appointed holydays as if he were present. After some time he rode over to see how all went on, choosing a festival day, that he might meet them in their holyday gayety. He was surprised, on approaching, to hear no merriment; and, on entering his fields, he found his "force" all hard at work. As they flocked round him, he inquired why they were not making holyday. They told him that the crop would suffer in its present state by the loss of a day, and that they had therefore put off their holyday, which, however, they meant to take by-and-by. Not many days after an express arrived to inform the proprietor that there was an insurrection on his estate. He would not believe it; declared it impossible, as there was nobody to rise against; but the messenger, who had been sent by the neighbouring gentlemen, was so confident of the facts, that the master galloped, with the utmost speed, to his plantation, arriving as night was coming on. As he rode in a cry of joy arose from his negroes, who pressed round to shake hands with him. They were in their holyday clothes, and had been singing and dancing. They were only enjoying the deferred festival. The neighbours, hearing the noise on a quiet working day, had jumped to the conclusion that it was an insurrection.

There is no catastrophe yet to this story. When the proprietor related it, he said that no trouble had arisen; and that for some seasons, ever since this estate had been wholly in the hands of his negroes, it had been more productive than it ever was while he managed it himself.

The finest harvest-field of romance perhaps in the world is the frontier between the United States and Canada. The vowed student of human nature could not do better than take up his abode there, and hear what fugitives and their friends have to tell. There have been no exhibitions of the forces of human character in any political revolution or religious reformation more wonderful and more interesting than may almost daily be seen there. The impression on even careless minds on the spot is very strong. I remember observing to a friend in the ferryboat, when we were crossing the Niagara from Lewistown to Queenstown, that it seemed very absurd, on looking at the opposite banks of the river, to think that, while the one belonged to the people who lived on it, the other was called the property of a nation three thousand miles off, the shores looking so much alike as they do. My friend replied with a smile, "Runaway slaves see a great difference." "That they do!" cried the ferryman, in a tone of the deepest earnestness. He said that the leap ashore of an escaped slave is a sight unlike any other that can be seen.

On other parts of the frontier I heard tales which I grieve that it is not in my power to tell, so honourable are they to individuals of both races, friends of the slaves. The time may come when no one will be injured by their being made public. Meantime, I will give one which happened many years ago, and which relates to a different part of the country.

A., now an elderly man, was accustomed in his youth to go up and down the Mississippi on trading expeditions; and both in these and in subsequent wanderings of many years—to Hayti among other places—he has had opportunity to study the character of the negro race; and he is decidedly of opinion that there is in them only a superinduced inferiority to the whites. In relating his experiences among the coloured people, he told the following story:—

When he was a young man, he was going down the Mississippi in a boat with a cargo of salt, when he stopped at a small place on the Kentucky shore called Unity, opposite to a part of Arkansas. While he was there a slavetrader came up with his company of upward of two hundred slaves, whom he was conveying to the New-Orleans market. Among these A. remarked a gigantic mulatto—handsome in countenance and proud in bearing—who was nearly naked, and fettered. He had an iron band round his waist and round each wrist, and these bands were connected by chains. The trader observed to A. that this man was the most valuable slave he had ever had on sale. I think he said that he would not take two thousand dollars for him; he added that he was obliged to chain him, as he was bent on getting away. When the trader's back was turned, the mulatto looked at A. as if wishing to talk with him.

"Why are you chained in this way?" asked A.

"Because my master is afraid of losing me. He knows that I am the most valuable slave he has, and that I mean to get away."
