Read it through once

I knew what was the matter with them. They were seasick. And I was glad of it. We all like to see people seasick when we are not, ourselves. Playing whist by the cabin lamps when it is storming outside is pleasant; walking the quarterdeck in the moonlight is pleasant; smoking in the breezy foretop is pleasant when one is not afraid to go up there; but these are all feeble and commonplace compared with the joy of seeing people suffering the miseries of seasickness.
