It was the 15th of July that I began to take a more particular survey of the island itself.  I went up the creek first, where, as I hinted, I brought my rafts on shore.  I found, after I came about two miles up, that the tide did not flow any higher, and that it was no more than a little brook of running water, and very fresh and good:  but this being the dry season, there was hardly any water in some parts of it, at least not enough to run into any stream, so as it could be perceived.

On the bank of this brook I found many pleasant savannas or meadows, plain, smooth, and covered with grass; and on the rising parts of them next to the higher grounds, where the water, as it might be supposed, never overflowed, I found a great deal of tobacco, green, and growing to a great and very strong stalk:  there were divers other plants which I had no notion of, or understanding about; and might perhaps have virtues of their own, which I could not find out.

I searched for the cassave root, which the Indians in all that climate make their bread of, but I could find none.  I saw large plants of aloes, but did not then understand them:  I saw several sugar-canes, but wild, and, for want of cultivation, imperfect.  I contented myself with these discoveries for this time, and came back, musing with myself what course I might take to know the virtue and goodness of any of the fruits or plants which I should discover, but could bring it to no conclusion; for, in short, I had made so little observation while I was in the Brasils, that I knew little of the plants of the field, at least very little that might serve me to any purpose now in my distress.

The next day, the 16th, I went up the same way again; and, after going something farther than I had done the day before, I found the brook and the savannas began to cease, and the country became more woody than before.  In this part I found different fruits, and particularly I found melons upon the ground in great abundance, and grapes upon the trees; the vines had spread indeed over the trees, and the clusters of grapes were just now in their prime, very ripe and rich.  This was a surprising discovery, and I was exceeding glad of them; but I was warned by my experience to eat sparingly of them, remembering, that when I was ashore in Barbary, the eating of grapes killed several of our Englishmen who were slaves there, by throwing them into fluxes and fevers:  but I found an excellent use for these grapes, and that was to cure or dry them in the sun, and keep them as dried grapes or raisins are kept, which I thought would be, as indeed they were, as wholesome, and as agreeable to eat, when no grapes might be had.

I spent all that evening there, and went not back to my habitation, which by the way was the first night, as I might say, I had lain from home.  In the night I took my first contrivance, and got up into a tree, where I slept well, and the next morning proceeded upon my discovery, travelling near four miles, as I might judge by the length of the valley, keeping still due north, with a ridge of hills on the south and north side of me.
