176 NATURE IN DOWNLANB 



In the course of a hot summer day on these shade- 

 less hiUs one may experience a variety of tempera- 

 tures and a succession of contrasted sensations. 

 Lying flat on the grass on a lower slope it is exces-

 merely to repose during the idle noonday hours. One 

 August day, on coming to the summit of Mount Harry, 

 west of Lewes, I found a company of rooks and daws
