The killers sounded cheerful
"The killers worked in the swamps from nine to four, half past four, as the sun would have it. Sometimes, if it rained too much, they came later in the morning. They came in columns, announcing their arrival with songs and whistles. They beat drums, they sounded very cheerful to be going killing for an entire day.
One morning, they would take one path, the next day another path. When we heard the first whistles, we disappeared in the opposite direction. One morning, they cheated, they came from all sides springing traps and ambushes; and that day was a very dispiriting one because we knew that that evening there would be more than the usual number of dead."
