The collection consists of Snow's diary (March 1-July 17 1866).
Most entries begin with an account of the weather and the attendance of evening and teachers' meetings, while Sunday entries include church and singing school attendance. Diary entries primarily concern the daily events of Snow's stay on Ebon, including the acquisition of food and supplies, trade, tribal interaction, and religious instruction. Early journal entries discuss attempts to purify saltwater for salt (March 1); Snow's house construction (March 3, 13, 17, April 5, 13); the hunting and raising of pigs (March 7, 23, April 9); trade with a man named Capelle, likely a ship captain, that includes molasses, butter, tea, pickles, ketchup, a duck, and oil (March 22, June 19); and book shipments (April 5).
The diary consistently refers to the native people of Ebon Atoll. Particularly interesting entries address a fleet of twenty-two canoes to Ebon that held three prominent local chiefs named Kaibuke, Loabbaiu, and Losak; the murder of one of Kaibuke's wives and her brother, as well as the murders of several chiefs (April 4); the fact that seventeen chiefs comprised of males, females, young and old people have died since Snow arrived in the South Pacific (April 7); and a meeting between a chief from Kosaie and the chiefs of Ebon (May 7).
Information related to religion and the conversion of the native peoples is found throughout the diary. Mentioned are Snow's translation of the Book of Mark into the Kusaie language (April 2-June 12); the probational reception of ten islanders into the church (April 11); the baptism of four children (May 6); an infant's death and the funeral (May 27); and the excommunication of a church member (June 8).
Many entries describe Chief Kaibuke's relationship with Snow and with the church. Included are that fact that Ebon and the Marshall Islands were the only stations in Micronesia where no chiefs belonged to the church (May 7); Kaibuke speaking during a church service (May 20); and Kaibuke's plan to tattoo his neck and face (June 13-14).
Throughout the diary, several entries mention Snow's fondness of chess, ships arriving and leaving the atoll, fishing, and interaction with Capelle. Also of interest is an account of a July Fourth celebration involving the raising of an American flag and the firing of double-barreled muskets.
