DETAILS OF THE 



CHIEF MOVEMENTS OBSERVED AT THE LIGHTS 



DURING THE SPRING OF 1908. 



For some not very obvious reason both the records and the 

 wings received from the lighthouses and lightships (with the 

 exception of St. Catherine's) were very few during the spring 

 of 1908. In going through the following list it should be 

 borne in mind that records from the lights are almost entirely 

 dependent on the age of the moon and local weather conditions, 

 and consequently negative evidence from such a source is of 

 no value at all, while, on the other hand, positive evidence is 

 practically conclusive proof that the particular species was 

 on the move.
