WTWHTAS
Chap 11, part 3.a

How that day passed I don't know. The sun climbed and the heat became almost unbearable. At noon the daily round of delirious shouts began. There were snatches of crazy song. By this time nearly all of us were holding long and serious conversations with people who weren't there. Jim Blood came up from Davy Jones' locker to talk to me a while.

I could hear his voice, but could not see him. He explained that in daylight and on the surface he had to be invisible. It was not very satisfactory. Then I heard a voice that made me jump. It was my son, Thomas, talking to me. When I left home he had been attached to a naval unit stationed in San Francisco.
