" Naturally the question suggests itself, Why did these people want the river now when nobody had wanted it in the five preceding generations? Apparently it was because at this late day they thought they had discovered a way to make it useful; for it had come to be believed that the Mississippi emptied into the Gulf of California, and therefore afforded a short cut from Canada to China. Previously the supposition had been that it emptied into the Atlantic, or Sea of Virginia. "
