These three immigrations produced a considerable increase 

 in the number o£ Grasshopper- Warblers ; but as the birds 

 M'ere silent on their arrival, they were generally overlooked 

 and were not recorded by our inland observers until they 

 commenced to sing. 



Curiously enough, however, the earlier records of this 

 species were mostly from inland counties, and apparently it 

 was not until well into the second week in May that its 

 distribution became general in the south. From the south- 

 eastern counties it was hardly recorded at all, and there can 

 be no doubt that in 1906 it was a rare bird in those 

 localities. 



From what has been said above it is clear that an attempt 

 at tracing its dispersal through the country must for the 

 present be purely speculative. 



Note. — The map merely illustrates the point of arrival of this 

 species and the first record from each county.
