INTRODUCTION xxi 



R. H. RASTALL, M.A., F.G.S., Fellow and Lecturer of Christ's College, Cambridge, 

 drew up an interesting report on the mineral constituents of gizzard grits in 

 Grouse, and gave assistance in writing the article dealing with grits which appears 

 in this Report. He also aided the work of publication by reading and correcting 

 almost the whole of the proofs of this Report. 



PERCY H. GRIMSHAW, F.R.S.E., F.E.S., Assistant Keeper of the Natural 

 History Department, Royal Scottish Museum, was appointed in 1909 to undertake 

 the whole investigation of the insect life on the moors. He carried on and 

 elaborated the work begun by Mr Fryer and Mr Hill, and not only prepared 

 a complete list of the insects found on the moors, but also reported upon 

 those eaten by the Grouse as shown by an examination of their crops and 

 gizzards. The result of his work is published in the " Annals of Scottish Natural 

 History" for July 1910, and in chapter iv. and Appendix E of the present 

 Report. Mr Grimshaw also undertook the investigation of the habits and life 

 history of the heather beetle (Loehmcea suturalis), and his article on this subject 

 is included in the Report. 



GEORGE C. MUIRHEAD, B.Sc., acted as Field Observer from May to December 

 1905, and assisted in drawing up the pamphlet " Notes on the Grouse." 



J. C. FRYER, B.A., Gonville and Caius College, Cambridge, was appointed in 

 1907 to make a report on the Insect Life of Grouse Moors. This Report has 

 already appeared in the Interim Report of the Committee. 



ALFRED HILL was employed in 1908 to carry on the investigations already 

 commenced by Mr Fryer. 



A. S. LESLIE, B.A., W.S. As soon as the Committee was officially appointed 

 in 1905, one of their first acts was to nominate Mr Leslie as Secretary. During 

 the six years that the Committee have sat he has continued to act in that capacity, 

 and his duties have been both varied and arduous. 



To him was entrusted the task of collecting the subscriptions, which formed the 

 sole source of income for the Inquiry, and without which nothing could be done ; the 

 control of this Fund further rested in him. He also got together and organised 

 the three hundred and sixty local correspondents, he drew up all the various tables, 

 forms, etc., with which these correspondents were supplied, received the answers to 

 the questions asked, collated and tabulated not only these answers but the verbal
