"When walking to and from the trenches in the darkness, I find it is a great help to study the stars (not for purposes of direction). I know very little about them, and I saw a very useful plan in, I think, the _Daily News_ of 3 April, called 'The Night Sky in April.' It was just a circle with the chief planets and stars shown and labelled. The periphery of the circle represented the horizon.
