     There're five people at our table, including myself. I've already learnt a great deal about them in the

short time we've been at sea, although we rarely meet except at meal times.

     First of all, there's Dr Stone. He's a man of about sixty five, with gray hair and a friendly face. He

gave up his work a short while ago and is now traveling round the world before he retires to some quiet

country village. As a young man, he served for many years as a doctor in the Army and visited many

countries. He's told us a lot about the city to which we are going.

     Then there's "Grandmother". I call her that because her name escapes me. In spite of being a

grandmother, she looks rather young, not more than fifty, She's on her way to visit a daughter who went

to Australia some years ago. Naturally she is very excited at the thought of seeing her again, and her

three grandchildren, whom she has never seen.

     Then there's a man I don't care for very much, an engineer by the name of Barlow. He has been on

leave in England and is now returning to his work in Singapore.

     The other person who sits at our table is Mrs. Hunt. I've found out hardly anything about her. She's

extremely quiet and rarely talks, except to consult (咨询) the doctor about children's various illness.

She's on her way to join her husband in India.
