We have again to teiuler our grateful thanks to the many 

 observers who have sent in Schedules weekly^ and without 

 whose assistance this enquiry would have been impossible. 

 In response to suggestions from many quarters, we have this 

 year published a list of these observers ; and by referring 

 to this, it will be seen that many districts are still but 

 sparsely watched. We shall therefore feel grateful to anyone 

 who can furnish us with the names and addresses of com-

 work. 



The Master and Elder Brethren of Trinity House have

The writer of the review appeared to think that the work 

 done by the British Association Committee was complete and 

 final, and that until " new methods " were applied further 

 investigation would not be likely to lead to any results 

 commensurate with the labours involved ; but, as the B.A. 

 Committee stated that they had " no wish to discourage the 

 prosecution of observations,^* we consider ourselves justified 

 in continuing the work. The sending in of weekly schedules 

 bv many observers and our investigations of the inland migra- 

 tions, which, as the B.A. Committee specially mention in their 

 final report, have been hitherto untouched, are undoubtedly 

 " new methods " of dealing with this difiicult subject. 



The reviewer also regretted that we should have published 

 a Report on the work of a single season, but he seems to 

 have forgetten that we were only elected for one year, and 

 that we could hardly ask for further support without showing 

 the members of the Club our methods and the results 

 obtained. It was made very clear in the Introduction that 

 the first Report only showed the results of one year and that
