Pray note, all this was the fruit of a disturbed mind, an impatient temper, made desperate, as it were, by the long continuance of my troubles, and the disappointments I had met in the wreck I had been on board of, and where I had been so near obtaining what I so earnestly longed for—somebody to speak to, and to learn some knowledge from them of the place where I was, and of the probable means of my deliverance. I was agitated wholly by these thoughts; all my calm of mind, in my resignation to Providence, and waiting the issue of the dispositions of Heaven, seemed to be suspended; and I had as it were no power to turn my thoughts to anything but to the project of a voyage to the main, which came upon me with such force, and such an impetuosity of desire, that it was not to be resisted.
When this had agitated my thoughts for two hours or more, with such violence that it set my very blood into a ferment, and my pulse beat as if I had been in a fever, merely with the extraordinary fervour of my mind about it, Nature—as if I had been fatigued and exhausted with the very thoughts of it—threw me into a sound sleep.
