"'Down the Great River,' by Captain Willard Glazier, gives an account of the discovery of the lake now generally asserted to be the source of the Mississippi; also a description of a canoe voyage during the summer of 1881, from the source to the mouth of the Father of Waters. A journey of over three thousand miles by canoe, and on a single stream, is in itself an arduous and remarkable undertaking, and one seldom, if ever, paralleled. Captain Glazier presents not only reasonable evidence to support his claim as the discoverer of the true source of the Great River, but gives an entertaining and instructive narrative of his researches and adventures, thus affording a graphic history and description of the Mississippi."

"'Down the Great River,' by Captain Willard Glazier, is an account of the author's voyage in 1881, from the source to the mouth of the Mississippi River in a canoe. It is a very interesting and instructive narrative from beginning to end; the descriptions of the scenery through which the river passes being unusually fine. In this volume the Captain presents his claim of having discovered beyond Lake Itasca another lake which is connected with Itasca by a well-defined stream, and consequently is the true source of the Mississippi."

"All who live in the valley of America's greatest river will be especially interested in knowing something of its source, its course, and the cities that line its banks. Since De Soto first discovered the Father of Waters in 1541, many eminent explorers have been associated with its history. Marquette, Joliet, La Salle, Hennepin, La Hontan, Charlevoix, Carver, Pike, Cass, and Beltrami preceded Schoolcraft. The last named discovered a lake which he supposed to be the source, but the Indians and the missionaries said there was a lake beyond. A learned few believed them. It remained for some explorer to make further investigation and publish the truth more widely to the world. This was done by Captain Glazier in 1881, who visited the lake, explored its shores and found it to be wider and deeper than Itasca."
