"Volume II," as Adams titled it, contains approximately 86 pages of text and drawings and features many more extensive, anecdotal, and undated entries than the first journal. Beginning in June 1854, Adams, as a part of three parties of the expedition, left Cantonment Stevens. Adams accompanied Harry Pierson to Olympia on the Puget Sound; crossing the Missoula River, proceeding up the Snake River to Fort Walla Wallah, to the Cascades, down the Columbia River by steamboat to Vancouver, to Portland and Oregon City, and to Olympia. In Olympia, Adams waited for Governor Stevens' return, and during that time, traveled to Fort Steilacoom, Hudson Bay Trading Post, Vancouver, Portland, and the Coeur d'Alene Mission. He finally traveled to Fort Owen.

At Fort Owen, Adams waited for news and provisions, and while there, noted that the Flathead Indians suffered from a scarcity of buffalo and hoped that the United States government would help them make peace with the Blackfeet and provide teachers to instruct their children. During the several months that Adams stayed at Fort Owen, he became acquainted with the Flathead chief, Victor, learned of inter-tribal problems and violence, and attended Native American ceremonies and events.

In April, Adams was notified that Governor Stevens would arrive in July and that treaties were to be made with Native Americans, including the Blackfeet, during the summer.

At the end of this journal are brief biographies of thirteen Native Americans along with pencil sketches of each. There is also a six page English to Indian language dictionary.
