Vol. xv.] 40 



Dr. Sclater exhibited a photograph which he had re- 

 ceived from Mr. Alwyn Haagner, of the Dynamite Factory, 

 Modderfontein, some years ago. It represented a pair of 

 lrrisor viridis as observed nesting in an old breeding-place 

 of Parus qfer, in the trunk of a Sanga-tree (Cursonia) . The 

 tree was felled, and three blue eggs, quite fresh, were taken 

 out of the hole, but only one of them was left unbroken by 

 the fall. 



Mr. H. F. Witherby read the following Report : — 



" The Sub-Committee appointed at the last meeting of 



the Club to enquire into the "migration of birds within 



these Islands " reports as follows : — 



"As to the composition of the Sub-Committee. 



" It is much to be regretted that Mr. W. Eagle Clarke 

 finds himself unable to serve on the Sub-Committee owing 

 to great pressure of other work, and also because it is most 

 important for the migration- work on which he is at present 

 engaged that he should have an entirely free hand. But 

 your Committee are very pleased to be able to announce 

 that Mr. Eagle Clarke is entirely in sympathy with the pro- 

 posed enquiry, which he regards as a very important under- 

 taking. Mr. Clarke has very kindly promised his advice, 

 an offer of which it is hardly necessary to say your 

 Committee will avail itself. 



" Your Committee asks for powers to add to their number 

 if and when it is found advisable. 



u As to the scope of the enquiry. 



" The conclusion has been reached that thoroughness 

 should be the chief aim in the present enquiry; with this 

 in view, the Sub-Committee propose to limit the enquiry at 

 first to the arrival in England and dispersal through England 

 and Wales of the thirty or so strictly migratory species which 

 winter abroad and nest fairly commonly in England and 

 Wales. 



"Although it has been thought best thus to limit the 

 enquiry during its first few months, your Committee are 

 anxious for your sanction to extend it as time goes on.
