He writes:

'...in the evening we were puzzled to know how we should pass the Imperial fleet in safety. They are somewhat random with their fire after dark, and might easily have taken us for Chinese, if not Rebel spies. Mr Edkins came to the rescue, proposing that we should sing as we passed them, that they might know we were foreigners. This suggestion seemed good and the boatmen were pleased with the idea... We approached some ships we took to be the fleet, and passed them singing lustily. But just as we were about to congratulate one another on our success, the boatmen shouted to us to recommence, as we had been mistaken in what we supposed to have been the fleet and were just coming within range of their guns. 

'So now we had to tune up again without delay...We concluded just opposite the largest ship of the fleet. It was now quite dusk.

'"What now?" cried Mr Edkins, as the alarm-gong struck on board the ship. 'There is not a moment to lose."

'He then commenced singing I know not what. Quaterman struck up a truly American tune...while I at the same moment raised a third with all the voice I could command. The men on the warship were shouting loudly, our boat's crew outdoing them if possible, and the whole thing was so ludicrous that I could control myself no longer. I burst into a fit of laughter most inappropriate to the occasion. 

'"Who goes there?" shouted a voice from the Imperial ship.

'"Bai-gui [white devils]," yelled our men, while we cried simultaneously, "Da Ying-guo" [Great Britain] and "Hua-qi-guo" which means Flowery Flag Country, or America. 

'After a little further explanation we were allowed to pass, upon which my companions began to lecture the boatmen for having called us 'white devils'. The poor men, who had not yet received their day's pay were very penitent.'
