The Surgeon's Log.
The photograph may be of interest to anyone who may have read the book, The Surgeon's Log; written by Dr. James Johnston Abraham who had made a voyage to Japan in a Blue Funnel ship which he had named-in the book- the CLYTEMNESTRA, but which as I (after long research) discovered was in fact the 1906 POLYPHEMUS. The voyage took place from January to June 1907.
In the book the captain was given the name Tucker and the second mate was a Mr Horner. Captain Tucker's real name was Chrimes (he later captained the ULLYSES), the second mate's name was, in reality, William Ambrose Holman and the man seated in the photograph was his son (he died aged 92 in Jan. 2006), his name was the same as his father's.
Note the walking stick which I am holding: I borrowed it from Bill just for the photo. He had inherited it from his father who had bought in Japan on one of his many voyages there.
