In each of the nations he visited, Gunn often traveled to the capital city and/or second largest population center with senior program officers of the RF to inspect existing or underway public health institutes, sanitary engineering measures, medical schools, and nursing schools. Gunn's trip to the United States describes his meetings and deliberations with the International Health Board's senior staff in New York and his inspection of medical training and laboratory facilities in the Boston (M.I.T.) and elsewhere.

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.

This diary contains the memoranda and letters sent by Raymond Fosdick to his various contacts within the Rockefeller Foundation, specifically recounting conversations and decisions made on the continuation and direction of the Rockefeller Foundation's work in the medical, natural, and social sciences. As the diary covers the pre- and post-WW II period, there is significant discussion on the appropriate actions for the Foundation to take in the continuation of its activities during the war and after in China and Eastern Europe in the early stages of the Cold War. Fosdick also highlights the Foundation's significant contributions to atomic research through Ernest Lawrence and Warren Weaver and his belief that the atomic age would continue to shape the Foundation's work in each of its other departments. This diary also reveals Fosdick's desires to reorganize the Foundation's efforts in all its programs to have greater impact and relevance, especially in the areas of the General Education Board and the Division of Medical Science.
