I had all this time observed no Sabbath day; for as at first I had no sense of religion upon my mind, I had, after some time, omitted to distinguish the weeks, by making a longer notch than ordinary for the Sabbath day, and so did not really know what any of the days were; but now, having cast up the days as above, I found I had been there a year; so I divided it into weeks, and set apart every seventh day for a Sabbath; though I found at the end of my account I had lost a day or two in my reckoning. A little after this, my ink began to fail me, and so I contented myself to use it more sparingly, and to write down only the most remarkable events of my life, without continuing a daily memorandum of other things.
The rainy season and the dry season began now to appear regular to me, and I learned to divide them so as to provide for them accordingly; but I bought all my experience before I had it, and this I am going to relate was one of the most discouraging experiments that I made.
