The deck log of the Juniata beginning 6 May 1883, lists P. F. Harrington as Commander. The list of officers on board includes Asa M. Mattice, P. Asst. Engineer. Also listed is “H. H. Colson, 1st Lieut., USMC, Marines on Board: 4 non-commissioned, 1 drummer, 20 privates.” A notation on the envelope containing the Mattice negative appears to identify the figures on the bridge as Dr. Woods, (Ichabod) Hobbs (Paymaster), Mattice, and (Richard) Mitchell.
