The U. S. surgeon from the Marine Hospital has been on board looking us over. Found only four diseases, measles, scurvy, typhoid fever and jaundice. He did not put down the graybacks that keep us scratching all the time. For a long time after they appeared they left me alone, but one morning as I lay on my back in bed writing in my diary one came crawling up over my knee and looked me straight in the face; from that on they have seemed to like me as well as anyone.
