io6 ADVENTURES AMONG BIRDS 



I had seen that day, the lichened farmhouses and 

 grey barns, trees and roads and purple hedges, red and 

 black cows in a green field, and gulls and rooks and 

 distant low hills and pine-woods, with many more, 

 had appeared to me but as a fringe and small parts of

 on their yellow beaks. The light wind ruffled their
