(March 25 1925. Wednesday, Tucson. My lecture course in Stratigraphic Paleontology came to an end this morning. Finished all to the close of the Paleozoic. The students are finding the course unusually hard, and with a few exceptions are not putting in the necessary time on the forms. The first exam was not a good result. Hoffman was good at 85%. Mordele was very near this mark, and the rest marked literally mine around 75%. At least I would have questioned many one of them excepting Hoffman and Mordele. October did not take the exam. Bullard failed badly. Next Friday comes the test on forms, and from what Stofanaw tells me, no more 3 or 4 girls do poorly will. The trouble is they don't work hard enough. When I read the papers I found out none of them good. Just fancy in Arizona.
