_Saturday, Feb. 12, 1842._--While the last experiments were being tried on the yearling, W. espied B., a farmer and tenant of M., with several men, at the distance of some fields, trying, most ineffectually, on the old system, to break-in a horse. W. proposed to go down and show him what effect had been produced on the yearling. The rest agreed, and W., M., and E. proceeded towards B., W. leading the yearling. On their way they had to lead her over a brook, which she passed after a little persuasion, _without force_. One of the fields through which she had to pass contained four horses, three of which trotted up and surrounded her, but she did not become in the least degree restive, or desirous of getting loose. When the party arrived at the spot, they found that B. and his men had tied their filly short up to a tree in the corner of a field, one side of which was walled, and the other hedged in. W. now delivered the yearling up to M., and proposed to B. to tame his horse after the new method, or (to use his own phrase) to "puff" it. B., who was aware of the character of his horse, anxiously warned W. not to approach it, cautioning him especially against the fore-feet, asserting that the horse would rear and strike him with the fore-feet, as it had "lamed" his own (B.'s) thigh just before they had come up. W. therefore proceeded very cautiously. He climbed the wall, and came at the horse through the tree, to the trunk of which he clung for some time, that he might secure a retreat in case of need. Immediately upon his touching the halter, the horse pranced about, and finally pulled away with a dogged and stubborn expression, which seemed to bid W. defiance. Taking advantage of this, W. leaned over as far as he could, clinging all the time to the tree with his right hand, and succeeded in breathing into one nostril, without, however, being able to blind the eyes. From that moment all became easy. W., who is very skilful in the management of a horse, coaxed it, and rubbed its face, and breathed from time to time into the nostrils, while the horse offered no resistance. In about ten minutes W. declared his conviction that the horse was subdued; and he then unfastened it, and, to the great and evident astonishment of B. (who had been trying all the morning in vain to gain a mastery over it), led it quietly away with a loose halter. Stopping in the middle of the field, with no one else near, W. quietly walked up to the horse, placed his arm over one eye and his hand over the other, and breathed into the nostrils. It was pleasing to observe how agreeable this operation appeared to the horse, who put up its nose continually to receive the "puff." In this manner W. led the horse through all the fields, in one of which were the four horses already mentioned, who had formerly been the companions of the one just tamed, and who surrounded it, without, however, making it in the least degree restive. At length W.
