Now I need not tell you that what impelled me to these actions was the desire to prevent my mother's death; whenever I touched any particular object, it was with the view of baffling the evil chance, as you would call it--in this instance my mother's death.
"A favourable crisis occurred in my mother's complaint, and she recovered; this crisis took place about six o'clock in the morning; almost simultaneously with it there happened to myself a rather remarkable circumstance connected with the nervous feeling which was rioting in my system.

I was lying in bed in a kind of uneasy doze, the only kind of rest which my anxiety, on account of my mother, permitted me at this time to take, when all at once I sprang up as if electrified, the mysterious impulse was upon me, and it urged me to go without delay, and climb a stately elm behind the house, and touch the topmost branch; otherwise--you know the rest--the evil chance would prevail.

Accustomed for some time as I had been, under this impulse, to perform extravagant actions, I confess to you that the difficulty and peril of such a feat startled me; I reasoned against the feeling, and strove more strenuously than I had ever done before; I even made a solemn vow not to give way to the temptation, but I believe nothing less than chains, and those strong ones, could have restrained me.

The demoniac influence, for I can call it nothing else, at length prevailed; it compelled me to rise, to dress myself, to descend the stairs, to unbolt the door, and to go forth; it drove me to the foot of the tree, and it compelled me to climb the trunk; this was a tremendous task, and I only accomplished it after repeated falls and trials.

When I had got amongst the branches, I rested for a time, and then set about accomplishing the remainder of the ascent; this for some time was not so difficult, for I was now amongst the branches; as I approached the top, however, the difficulty became greater, likewise the danger; but I was a light boy, and almost as nimble as a squirrel, and, moreover, the nervous feeling was within me, impelling me upward.
It was only by means of a spring, however, that I was enabled to touch the top of the tree; I sprang, touched the top of the tree, and fell a distance of at least twenty feet, amongst the branches; had I fallen to the bottom I must have been killed, but I fell into the middle of the tree, and presently found myself astride upon one of the boughs; scratched and bruised all over, I reached the ground, and regained my chamber unobserved; I flung myself on my bed quite exhausted; presently they came to tell me that my mother was better--they found me in the state which I have described, and in a fever besides.
