The publishers of Captain Willard Glazier's Works, having recently had their attention drawn to sundry articles in the public prints calling in question his claim to have located the source of the Mississippi, conclude to invite the consideration of the reader to a few of the many press notices, letters of endorsement and other papers placed at their disposal by friends of the explorer, bearing directly upon the subject of the primal reservoir or true source of the Great River. In view of the apparent incredulity of some critics, it is thought expedient to lay this matter before the public in connection with Captain Glazier's latest work, "Down the Great River," which gives a detailed account of his discovery, in order that a sound and enlightened conclusion may be arrived at upon the merits of the claim presented.
