the most part, to have slipped away in small parties, mostly 

 unobserved, so that our records during that period are 

 neither so complete nor so detailed as we could have 

 wished. 



During the latter part of 1012 Mr. J. L. Bonhote, one o£ 

 the original members of the (,'ommittee, having taken up 

 work abroad, found it necessary to resign his post, and 

 Mr. M. Vaughan took his place on the C'Ommittee. It is 

 with much regret that we lose the help of our colleague, 

 who during the earlier years of our work filled the onerous 

 post of secretary, and it was largely owing to his powers of 

 organisation that our scheme was successfully started. The 

 immense amount of time and labour that he devoted to it 

 can only be fully appreciated by those actually engaged in 

 the work. 



Our best thanks are again due to the Master and Elder 

 Brethren of the Trinity House for the continuance of their 

 permission to enlist the services of the light-keepers, and 

 to the latter as well as to our many inland observers, 

 without whose kindly co-operation our enquiry could not be 

 carried on.
