The coasts of the lakes up which the _Griffin_ led the oarless way are three thousand three hundred and eighty-five miles in length, or, including those of the lower lake, Frontenac, which was also first touched of French keels, over four thousand miles. The statistics of the traffic which has grown in the furrow of that wind-drawn plough would be fatiguing if they did not carry you to heights of a wider and more exhilarating view. We have occupied and apportioned the billion acres of French domain among sixty million people. Here is an added domain in which no landmarks can be set--which belongs to all men. These are a few graphic facts gathered from recent reports and books about the Great Lakes: [Footnote: Edward Charming and M. F. Lansing, "The Story of the Great Lakes." Macmillan, New York, 1909. James O. Curwood, "The Great Lakes." Putnam, New York, 1909. James C. Mills, "Our Inland Seas." McClurg, Chicago, 1910.] Nearly as many people live in States that have ports upon those shores as in France to-day--between thirty-five and forty millions. The lakes have a tonnage equal to one-third of the total tonnage of North America. [Footnote: Curwood, "The Great Lakes," p. 4. "In 1913 the total tonnage of the Great Lakes was 2,940,000 tons, of the United States 7,887,000 tons."--Report United States Commission of Navigation.] They have made possible a saving in cost of transportation (and so of production) of several hundred million dollars in a single year. [Footnote: Curwood, "The Great Lakes," p. 4.] Only ninety million dollars have been spent by the government for their improvement in the whole history of their occupation, above Niagara Falls, [Footnote: Curwood, "The Great Lakes," p. 9.] while France in that time has spent for harbors and waterways alone seven hundred and fifty million dollars.[Footnote: "Four hundred and fifty million dollars of this total has been for the improvement and maintenance of the waterways."--Report of National Waterways Commission, p. 507.] They have been privately developed. Six times as much freight passes over these lakes as through the Suez Canal in a year. [Footnote: Curwood, "The Great Lakes," p. 6.] Three thousand five hundred vessels, and more than twenty-five thousand men are required to move the hundred million tons of freight which every year would fill a train encircling the globe. [Footnote: Curwood, "The Great Lakes," pp. 25, 26, and Report of United States Commission of Navigation, 1913.] If one were to stand on the shore of that "charming strait," between Erie and Huron, the Detroit River (which Hennepin so covetously describes, wishing to make settlement there, until La Salle reminded him of his "professed passion for exploring a new country"), one would now see a vessel passing one way or the other every twelve minutes, on the average, day and night during the eight months of open navigation.
