The next day, the 29th of June, [165] we entered the lake, which is some fifteen leagues long and seven or eight wide. [166] About a league from its entrance, and on the south side, is a river [167] of considerable size and extending into the interior some sixty or eighty leagues. Farther on, on the same side, there is another small river, extending about two leagues inland, and, far in, another little lake, which has a length of perhaps three or four leagues. [168] On the northern shore, where the land appears very high, you can see for some twenty leagues; but the mountains grow gradually smaller towards the west, which has the appearance of being a flat region. The savages say that on these mountains the land is for the most part poor. The lake above mentioned is some three fathoms deep where we passed, which was nearly in the middle. Its longitudinal direction is from east to west, and its lateral one from north to south. I think that it must contain good fish, and such varieties as we have at home. We passed through it this day, and came to anchor about two leagues up the river, which extends its course farther on, at the entrance to which there are thirty little islands. [169] From what I could observe, some are two leagues in extent, others a league and a half, and some less. They contain numerous nut-trees, which are but little different from our own, and, as I am inclined to think, the nuts are good in their season. I saw a great many of them under the trees, which were of two kinds, some small, and others an inch long; but they were decayed. There are also a great many vines on the shores of these islands, most of which, however, when the waters are high, are submerged. The country here is superior to any I have yet seen. The last day of June, we set out from here and went to the entrance of the River of the Iroquois, [170] where the savages were encamped and fortified who were on their way to make war with the former. [171] Their fortress is made of a large number of stakes closely pressed against each other. It borders on one side on the shore of the great river, on the other on that of the River of the Iroquois. Their canoes are drawn up by the side of each other on the shore, so that they may be able to flee quickly in case of a surprise from the Iroquois; for their fortress is covered with oak bark, and serves only to give them time to take to their boats.
