Imagery is the clue to conduct. Without mental imagery there can be no development of character. Without mental imagery there can be no social progress. This mental imagery comes from the experience of life. You are not the sole purveyors of it. Books, as I have said, are dead and inert things until men with some experience of life come to them for further insight and for guidance as they go their way trying to understand life and to interpret it more truly and to get out of it greater richness. There is a delight in mental pictures. May our pictures be interesting and true and ennobling, may they increase in number as the years go on, may they open up to us vistas of personal satisfaction, give us keener insight into the meaning of life and stir us to larger loyalties and to truer service. May we pledge ourselves to this great work and to the furthering and fostering of those things which Watson has so finely called "the things that are more excellent." "The grace of friendship, mind and heart Linked with their fellow heart and mind, The gains of science, gifts of art, The sense of oneness with our kind, The thirst to know and understand, A large and liberal discontent, These are the goods in life's rich hand, The things that are more excellent." At the conclusion of President Vincent's address, Mr. Lawrence J. Burpee announced that M. Amedee Tremblay, organist of the Basilica, would accompany a number of Canadian folk songs which M. Normandin, of Montreal, would sing. They were given in three groups of three, and between each group was given one of Dr. Drummond's poems in character, by Mr. Heney, of Ottawa, a most excellent interpreter of these sketches of the French-Canadian habitant. These unique, interesting and well rendered contributions to the exercises of the evening were much appreciated by all present, and at their conclusion the session closed with a brief but hearty expression of acknowledgment from President Elmendorf. SIXTH GENERAL SESSION (Russell Theatre, Tuesday, July 2, 3 p. m.) President Elmendorf occupied the chair. Mr. CARR: Many of us appreciate the work done in days past by Frederick W. Faxon, in personally conducting our post-conference tours. Business obliged him to take another course this year and cross the water. It has been suggested that we send him a wireless despatch of appreciation and felicitation in the name of the association. Madam President, I move the authorization of such a telegram. The motion was carried unanimously, and the cablegram ordered sent. The PRESIDENT: Now, we will proceed with the regular program, which brings us to the last of our series growing out of the idea of service to the individual, and we shall take pleasure in hearing Mr. CARL B. RODEN, assistant librarian, Chicago public library, on BOOK ADVERTISING: INFORMATION AS TO SUBJECT AND SCOPE OF BOOKS
