From that day, however, the Iroquois were the bitter enemies of the French, and this enmity seriously interfered with the successful carrying out of French plans. Having control of the St. Lawrence River, France greatly desired to get control of the Mississippi River as well. Once securing possession of these two great streams, she would come into possession of the wealth of the North American Continent. But the Iroquois Indians were strongly posted in the Mohawk River Valley, and thus held the key to the situation. In this way they blocked the path of the French, who wished to reach the Ohio and the Mississippi through Lake Erie and Lake Ontario. So the French were driven to seek a route farther north, a route which was much longer and more difficult. It would be well for you to trace on your map this roundabout way, which extended up the Ottawa River into Georgian Bay, through Lake Huron and Lake Michigan, across into the Illinois River, and through that into the Mississippi. In the same year that Champlain made the Iroquois bitter enemies of the French, Henry Hudson won their lasting friendship for the Dutch. About the time the Frenchman was fighting in the battle against the Mohawks at Ticonderoga, Hudson, with a crew of twenty men in the Half Moon, was sailing up the river that now bears his name. Instead of finding the short passage to the Pacific, for which he was searching in the interests of the Dutch, he discovered the great water-way to the interior. Having received just treatment from him, the Iroquois Indians became his friends and the friends of the Dutch settlers and traders that came later. From that time, in fact, these Iroquois Indians were as ready to sell their furs to the Dutch and to the English, who in 1664 took New York away from the Dutch, as they were to oppose the French and compel them to go many hundred miles out of their way in the tedious explorations in search of the Mississippi. This toilsome work of exploration was largely accomplished by the Jesuit missionaries. Fearless in their heroic efforts to advance their faith, they suffered all sorts of hardships, many being put to death, in their earnest struggle to bring religious truth to the ignorant red men of the woods. In their journeys through the forests and over the lakes, these Jesuit Fathers made many valuable discoveries and explorations which they carefully recorded in their journals. It was one of these missionaries, Father Marquette, who succeeded in reaching the waters of the Mississippi. Attended by Joliet and five other Frenchmen, he went, in 1673, as far down the mighty river as the mouth of the Arkansas. This was sixty-five years after Champlain made his settlement at Quebec.
