PREFACE. V 



much of the original matter was of ephemeral or 

 collateral interest. 



Bulletin No. IX, now mostly in the press, will 

 contain extracts from the annual reports made to Gov- 

 ernment up to the current year ; these will show the 

 operations actually undertaken and the progress made in 

 translating ideas and proposals into fact. The final 

 paper in that Bulletin will contain suggestions based 

 on the experience of the past ten years. 



^th September 1915. F. A. NICHOLSON.
