When he returned to Montreal, he found a great change had occurred in political affairs. It had become evident that the Iroquois were mere agents of the English. The Albany traders had searched the land between the Hudson River and Lake Erie, and had made a report that the Valley of the Genesee was fertile and beautiful to behold, and every year an increasing number of pale-faces wandered among the Indian villages toward Lake Ontario. Old officers in Canada saw that their only hope was to destroy the source of supply to the Iroquois. The question to be determined was whether the King of France or the King of England should control the region of the Great Lakes. Chevalier de Callières, who had seen much service in Europe, and was in command of the troops in Canada, insisted that decisive steps should be taken. The crisis was hastened by the arrival of the intelligence that a revolution had occurred in England, and that William and Mary had been acknowledged. Callières wrote to Seignelay relative to the condition of affairs: “It would be idle to flatter ourselves with the hope to find them improved since the usurpation of the Prince of Orange, who will be assuredly acknowledged by Sir Andros,[527] who is a Protestant, born in the Island of Jersey, and by New York, the inhabitants whereof are mostly Dutch, who planted this colony under the name of New Netherland, all of whom are Protestant.” He urged that the war should be carried into New York, and that a force be sent strong enough to seize Albany, and then to move down and capture Manhattan. “It will give his Majesty,” he said, “one of the finest harbors in America, accessible at almost all seasons, and it will give one of the finest countries of America, in a milder and more fertile climate than that of Canada.” The sequel was a conflict of drilled troops under European officers upon the borders of New England and New York. * * * * * CRITICAL ESSAY ON THE SOURCES OF INFORMATION. =1609-1640.=—The _Voyages_ of Champlain, as published in 1632 at Paris, are valuable in facts pertaining to discovery along the shores of Lake Champlain and Lake Huron; but the book is the subject of special treatment in another chapter.[528] The _Grand Voyage_ of Sagard[529] contains little more than what may be found in Champlain and the _Relations_ of the Jesuit missionaries. Charlevoix mentions that Sagard passed “some time among the Hurons, but had not time to see things well enough, still less to verify all that was told him.”
