REVIEWS. 31 



of the Sand-Martin and otlier species were recorded even as late 

 as the first week in June. 



One of the chief aims of the investigation shoukl be, we think, 

 to trace where the birds of each immigration settle down to nest, 

 and whether all the individuals of one species nesting in a 

 particular district arrive in the same immigration. Evidence 

 on these points is somewhat vague. 



Points of general interest which are confirmed in this 

 second Eeport are that the west of England was in many 

 cases populated before the east ; that there is a well-defined . 

 route passing due north through Devon and Wales ; and that 

 the large race of the Wheatear arrives not earlier than April 9th. 



We have drawn attention to the points above mentioned by 

 way of suggestion rather than criticism, and we fvilly believe 

 the Committee will work out, in the course of a few years, this 

 intricate and difficult problem in a thoroughly satisfactory way. 

 The results of their labours become more and more valuable 

 year by year as additional or confirmatory information is 

 collected, and everyone at all interested in the migration of 

 birds should study these Reports and keep them for future 

 reference. The proceeds from the sales of the Reports are 

 devoted to the furtherance of the enquiry.
