_Friday, Feb. 11, 1842._--In the morning W. and M. brought the filly from the stable to the front of M.'s house. The filly was quite wild, and on being first taken out of the stable she bolted, and dragged W., who only held her by a short halter, through a heap of manure. W. changed the halter for a long training halter, which gave him such power over her that he was easily able to bring the little scared thing up to the front of the house. Both M. and W. seemed much amused, and laughingly asked E. (the Communicator) to instruct them in Catlin's method of taming horses. E. did so as well as he could, quoting only from memory. The experiment was not tried very satisfactorily, but rather under disadvantages. The filly was in the open air, many strangers about her, and both the experimenters were seeking rather amusement from the failure than knowledge from the success of their experiment. W. kept hold of the halter, and M., with considerable difficulty, for the filly was very restive and frightened, managed to cover her eyes. He had been smoking just before, and the smoke must have had some effect on his breath. When he covered her eyes, he _blew_ into the nostrils, but afterwards, at E.'s request, he _breathed_; and, as he immediately told E., directly that he began to breathe, the filly, who had very much resisted having her eyes covered and had been very restive, "_stood perfectly still and trembled_." From that time she became very tractable. W. also breathed into her nostrils, and she evidently enjoyed it, and kept putting up her nose to receive the breath. She was exceedingly tractable and well behaved, and very loth to start, however much provoked. The waving of a red handkerchief, and the presenting of a hat to her eyes, while the presenter made a noise inside it, hardly seemed to startle her at all. _Saturday, Feb. 12, 1842._--This morning the filly was again led out to show its behaviour, which was so good as to call forth both astonishment and praise. It was exceedingly tractable, and followed W. about with a loose halter. Attempts were made to frighten it. M. put on a long scarlet Italian cap, and E. flapped a large Spanish cloak during a violent wind before its eyes, and any well broken-in horse would have started much more than did this yearling. EXPERIMENT THE SECOND. SUBJECT--_A Filly, three years old, coming four, and very obstinate; quite unbroken-in._
