The third boat was given up to men lying down or sitting up together, leaving only just room for the rowers, while the fourth and largest boat was being towed; the thwarts, that in an ordinary way would have been occupied by rowers, now holding the marines, who sat with their rifles ready, and fixed bayonets, while the stern-sheets were filled with Chinamen, seated in three groups, and all in the most uncomfortable-looking way.  I could see that their hands were tied behind their backs, and it was horribly plain that several of them were wounded; but why they should have formed these three groups, and sat there with their heads laid close together, was what puzzled me.
