Holmes's D&D excerpt: players' jobs

"One player should map the dungeon from the Dungeon Master's descriptions as the game progresses. This is easiest done if he uses a piece of graph paper marked North, East, South, West with entrance to the dungeon level drawn near the center. One of the players should keep a 'Chronicle' of the monsters killed, treasure obtained, etc. Another should act as 'caller' and announce to the Dungeon Master what action the group is taking. Both mapper and caller must be in the front rank of the party."
