Set out for the Natural History Museum. Reached Dr Clyde Fisher, Curator of the Planetarium and of Geology. A charming white-haired gentleman. He was interested in me (because of Professor Johnson’s introduction) and in Australites, which I had taken. I promised to send him a set for the Planetarium's exhibit, which I must do as soon as I get home. He called in Dr Chester Reeds, Geology, and the meteorite assistant, Mr Arthur Draper. I showed them the Australites and the other representative tektites. They, or rather Dr Chester, was definitely antagonistic to the idea of glass meteorites. He thinks they are volcanic. However, each one of the four of us chipped in and said his piece. I advocated their meteoritic origin very strongly. But if I could see or hear any reasonable volcanic explanation (which I do not think probable) I would forsake the meteorite readily. Today I determined to write that paper Dr Leonard asked for, for the American Association for the Advancement of Science, and I shall call it ‘Tektites (Australites)—Are they Glass Meteorites?’

To Columbia University, where Professor Douglas Johnson had a group of geologists to meet me. Several not there owing to other engagements, but I heard one remark to another that he’d not seen such a showing of University and Museum geologists for a long time. There were eleven professors, including Directors of Museum Departments. Professor Johnson, Professor Sharp, his chief man, Professors Krieger and Law, his department, Professor W. K. Gregory, dinosaurs and vertebrates, Professor Lobeck, petrology, Professor Chester Reeds, Museum, Dr Clyde Fisher, planetarium, and three other geological professors. Eleven. Most pleasant. Dinner in the Faculty Club at Columbia. Yarning. Australites. Everything was very pleasant. Professor Johnson is a most remarkable host in putting everyone at ease.

Gave the lecture. 70 to a hundred there, six professors. The slides went well. I think they enjoyed it, and understood something about Australia. It lasted over an hour and though I was told that some of them had lectures, no one left. Then Professor Johnson handed me a cheque from someone’s funds for $50, which was very fine, and quite undeserved. Professor D. W. Johnson has made this New York visit memorable.
