DAVID TO LECTURE ON AVIATION

Evan J. David '07, business manager of the aeronautical magazine, "Flying," will lecture on "Aviation in War and Peace" in Brattle Hall this evening at 8 o'clock. He will illustrate his points with lantern slides and, in addition, will show motion pictures of actual airplane warfare on the western front. The lecture is being given especially for members of the University, but the public may attend.

In his address Mr. David will cover the types of aircraft used on the battle front and in the United States training camps: fighting and bombing machines, scouts, battleplanes, hydroairplanes, flying boats, seaplanes, balloons, kites and observation craft. He will also discuss the various methods of fighting, famous fighters, and changes in methods.

Since his graduation from the University in 1907 the lecturer has had a long experience in all branches of the aviation service. He is author of "The War in the Air" and other books of wide circulation. Since the outbreak of the war he has made several trips to the fronts and has performed many investigations.

Tickets for the lecture are on sale at Amee Brothers and at Brattle Hall, for 50 cents and $1.
