Map to show that a bird leaving Norway, near Aalsund, might be 

 carried round the British Islands in twenty- four hours. The 

 arrows indicate the actual directions and force of wind at the 

 times marked during a slow-travelling circular storm in 

 autumn 1901. Speed of bird about twenty-five miles per hour.
