"Capella" arrived at San Diego, California, 19 March 1922 to carry cargo along the west coast until July, when she returned to the east coast for similar duty in the next 4 months. Back in California waters in November, "Capella" sailed to Japan in October 1923 to bring food and medical supplies, donated by American citizens, as well as water for the relief of earthquake-desolated Yokohama.
