Second Relief

       Little is known about Stone; he was one of the three vigorous young men — “the boys,” Reed called them — who arrived at the lake camp a day ahead of the rest of the Second Relief. Reed left him to take care of the handful of emigrants at the lake camp, but Stone disliked the look of the weather and deserted, along with Charles Cady. What became of him afterwards is uncertain, but H. H. Bancroft believed that he may have been the individual named Stone killed by Indians in Lake County in 1849.
