The collection comprises one autograph manuscript diary from William P. Gray's 1868 trip to Alaska and approximately forty autograph letters, signed, to William Henry Gray and members of his family. The diary documents William P. Gray's month-long trip by steamer from Oregon to Sitka, Alaska. Gray records details of his voyage, including traveling through the Queen Charlotte Sound; spotting Fort Tongass, the southernmost point of Alaska, and discussing politics with United States Army officers from the Fort; and passing a boat of Native Alaskans in the Clarence Strait. After arriving in Sitka, Gray records his impressions of the settlement's Native Alaskan, American, and Russian inhabitants; the scenery and climate; Alaska's potential self-government; and resources, including gold. The family letters include letters from family members in New York and other areas of the United States to William Henry Gray, his wife Mary Gray, his son James Gray, and his son-in-law Jacob Kamm.
