The Honse-Martin arrived along the whole of the sonth coast, 

 but in greatest numbers on its western half. One that had 

 evidently remained throughout the winter was seen at 

 Hampton Court on the 10th o£ January. 



The earliest arrival reported was in Sussex on the 25th of

 and Kent on the 5th, 9th, 10th and 11th of May. At the
