When Major Erastus Edward Strobino served at the 109th Station Hospital on New Caledonia, he kept a travelogue/nature journal of his time there. The journal records his voyage to New Caledonia and his stay on the island, from January 1942 to March 1943, though some later entries are undated. Although the journal started as a travelogue of his journey from the United States to New Caledonia, the content of the journal focuses on observations and discussions of star constellations viewed from the Southern Hemisphere, New Caledonia's flora and fauna and their adaptation to the environment, the island's landscape, its indigenous diseases and medicine, and its seasons and weather. His journal entries also describe his visits to a plantation, a farm, and one of his hikes up one of the island's mountains. His journal entries are illustrated with pencil drawings and photographs.

The journal is preserved as black-and-white photocopies and printed color scans held in a binder. A photograph of Major Erastus Edward Strobino in uniform from 1942 accompanies the journal.
