This diary records Mr. Mason's interviews and travels between January 2 and December 30 1930. The diary shows that he met with and interviewed natural science researchers and university administrators both in the United States and Europe, and coordinated with the Rockefeller Foundation's senior staff to ensure funding of projects to a maximum number of candidates at the earliest part of the Great Depression in the United States. While the depression is never directly referenced, the diary contains a copy of the "New Mexico Tax Bulletin" of 1930, a 23-page report which provided figures, estimates, and conclusions on the size and scope of the state's bonded debt in 1930. On a separate note, more than half the diary appears to be handwritten notes penned (almost illegibly) by Mason spanning several weeks and topics.
