It was not the wonders nor the beauty of the Cataract that impressed itself upon the minds of those savages, and that led them to furnish to Champlain--and so to the white man's world--the very first knowledge of the existence of Niagara. No! What most impressed the Cataract upon the minds of those Aborigines was the fact that at this point, the Falls themselves, together with the Rapids for a short distance above them, and for a long distance below them, were an insuperable obstacle to water--that is, canoe--navigation; that here they were obliged to make a long "portage." It was the only break in an otherwise uninterrupted water travel of hundreds of miles; which, going westward, extended from a point on the St. Lawrence, many miles east of the outlet of Lake Ontario, clear to the farthest end of Lake Superior; and which, coming eastward, extended nearly 1,500 miles, from where the City of Duluth now stands even until it reached the bitter waters of the Atlantic Ocean in the Gulf of the St. Lawrence. In the same volume, "Des Sauvages," appeared a poem by one "La Franchise," addressed to Champlain, in which mention is made of the "Saults Mocosans" or Mocosan Falls, "which shock the eyes of those who dare to look upon that unparalleled downpour." Mocosa was the name of that territory vaguely called Virginia, and which seems to have embraced everything from New York to Florida, extending indefinitely to the west and northwest. The allusion is generally considered to refer to Niagara; thus making Niagara's appearance in Poetry cotemporaneous with its appearance in prose. In 1609, Lescarbot published his "Histoire de la Nouvelle France," wherein he quotes extensively (including the references to Niagara) from Champlain; the work being reissued in several editions in subsequent years. And in 1610, Lescarbot, who was a great admirer of Champlain (he may himself have been "La Franchise"), produced a poem, wherein he speaks of the "great falls" which the Indians encounter in going up the St. Lawrence, from below the present site of Montreal, "jusqu'au voisinage de la Virginia"; which, under the above-noted boundaries of Virginia, has been stretched in imagination to include Niagara, but more likely meant the Rapids of the St. Lawrence. Champlain, in the map which he made in 1612, notes a "waterfall," but places it at the Lake Ontario end of the river; still it is clearly meant for Niagara. Early references to this Niagara Region--which up to about the middle of the 17th Century was owned and occupied by the Neuters, and after that time by their conquerors and annihilators, the Senecas--are to be found in that wonderful series of Reports made by the Catholic Missionaries in Canada to their Superiors in France, during a large part of the 17th Century, and known as the "Jesuit Relations."
