322 THE GROUSE IN HEALTH AND IN DISEASE 



about which he has but too often the most vague ideas. Again, 

 if any advance is to be made in methods of moor management, 

 it is obvious that the details must be worked out by the practical 

 man on the spot ; this can only be done if the keeper realises 

 the nature of the difficulties to be met, and the reasons for 

 which the suggested remedies are put forward. 



In recapitulating certain findings of the Committee it will 

 not be necessary to go into questions of purely scientific interest, 

 still less to set out again at any length the facts established 

 in former chapters. As far as possible, scientific nomenclature 

 will be avoided, and only such matters dealt with as bear 

 directly on the health of moors. 



Briefly stated, the " Grouse Disease " Committee claim to 

 have defined the main in their opinion the only primary 

 causes of what is commonly known as " Grouse Disease." 



During the six years of their investigation they have ex- 

 amined outbreaks of disease in every Grouse-producing county 

 of England, Scotland, and Wales. 



They have dissected birds, not only in the laboratory, but 

 freshly killed in the vicinity of the moor ; they have had the 

 advantage of all the conveniences of modern and recently devised 

 scientific appliances ; they have been kept accurately informed 

 of the outbreaks of disease, and by means of a network of 

 correspondents extending to every part of the Grouse-producing 

 area, have been able to observe the epidemic in every phase of 

 its progress. 



Apart from these advantages, not enjoyed by any former 

 body of inquirers, the Committee were assisted by field observers 

 of experience, who reported and classified variations in local 

 conditions. In the main divisions of research entomological, 

 pathological, helminthological, parasitical, botanical into which 

 the Inquiry resolved itself, it had the whole-hearted co-opera- 

 tion of a large and experienced staff of investigators, and the 

 help and advice of many leading men of science to whom 

 the subject has directly or indirectly appealed. 



After examining nearly two thousand cases of death from
