He was also desirous of presenting one of his canoes, the "Itasca," to the Missouri Historical Society in recognition of the unbounded hospitality he had enjoyed at the hands of the citizens of St. Louis, and it was decided that the donation of the canoe, a beautiful specimen of the Rob Roy pattern, should take place on the night of the lecture. Accordingly, on the evening of January fourteenth, a large audience consisting of members of the Historical Society, Academy of Sciences, clergy, officers and teachers of the public schools, and the various boat clubs of the city, assembled at Mercantile Library Hall to listen to his thrilling lecture on the pioneer explorers of the Mississippi, and to witness the formalities of the presentation. At eight o'clock, Captain Glazier, accompanied by Judge Albert Todd, an eminent lawyer, and vice-president of the Historical Society, made his appearance on the platform, and, after the storm of applause which greeted their entry had subsided, Judge Todd stepped to the front and introduced the lecturer in the following terms:-- Mark Twain wrote that in his oriental travels he visited the grave of our common ancestor, Adam, and as a filial mourner he copiously wept over it. To me, the grave of our common ancestress, Eve, would be more worthy of my filial affection; but instead of weeping over it, I should proudly rejoice by reason of her irrepressible desire for knowledge. She boldly gratified this desire, and thereby lifted Adam up from the indolent, browsing life that he seemed disposed and content to pass in the "Garden," and gave birth to that spirit of inquiry and investigation which is developing and elevating their posterity to "man's pride of place"--"a little lower than the angels," by keeping them ever discontented with the status quo, and constantly pressing on to the "mark of their high calling" beneath the blazing legend "Excelsior." It is the ceaseless unrest of the spirit, one of the greatest evidences of the soul's immortality, that is continually contracting the boundaries of the unknown in geography and astronomy, in physics and metaphysics, in all their varied departments. Of those pre-eminently illustrating it in geography were Jason and his Argonauts; Columbus, De Gama and Magellan; De Soto, Marquette and La Salle; Cabot and Cook; Speke, Baker, Livingstone and Franklin; and our own Ledyard, Lewis, Clarke, Kane, Hall and Stanley. And this evening will appear before you another of these irrepressible _discontents_ who would know what is still hidden at any risk or privation.
