I acquainted them with my design of discovering other nations, to preach to them the mysteries of our holy religion, at which they were much surprized, and said all they could to dissuade me from it. They told me I would meet Indians who spare no strangers, and whom they kill without any provocation or mercy; that the war they have one with the other would expose me to be taken by their warriors, as they are constantly on the look-out to surprize their enemies. That the Great River[2] was exceedingly dangerous, and full of frightful monsters who devoured men and canoes together, and that the heat was so great that it would positively cause our death. I thanked them for their kind advice, but told them I would not follow it, as the salvation of a great many souls was concerned in our undertaking, for whom I should be glad to lose my life, I added that I defied their monsters, and their information would oblige us to keep more upon our guard to avoid a surprize. And having prayed with them, and given them some instructions, we set out for the Bay of Puan,[3] where our missionaries had been successful in converting them.... The next day, being the 10th of June, the two guides [Miamies] embarked with us in sight of all the village, who were astonished at our attempting so dangerous an expedition. We were informed that at three leagues from the Maskoutens, we should find a river which runs into the Mississippi, and that we were to go to the west-south-west to find it, but there were so many marshes and lakes, that if it had not been for our guides we could not have found it.... Before embarking we all offered up prayers to the Holy Virgin, which we continued to do every morning, placing ourselves and the events of the journey under her protection, and after having encouraged each other, we got into our canoes. The river upon which we embarked is called Mesconsin [Wisconsin]; the river is very wide, but the sand bars make it very difficult to navigate, which is increased by numerous islands covered with grape-vines. The country through which it flows is beautiful; the groves are so dispersed in the prairies that it makes a noble prospect; and the fruit of the trees shows a fertile soil. These groves are full of walnut, oak, and other trees unknown to us in Europe. We saw neither game nor fish, but roebuck and buffaloes in great numbers. After having navigated thirty leagues we discovered some iron mines, and one of our company who had seen such mines before, said these were very rich in ore. They are covered with about three feet of soil, and situate near a chain of rocks, whose base is covered with fine timber. After having rowed ten leagues farther, making forty leagues from the place where we had embarked, we came into the Mississippi on the 17th of June [1673].[4]
