MOOR MANAGEMENT 341 



without fear of disease developing locally, i.e., among 

 the home stock of Grouse. 



(2) That drainage is very beneficial. 



(3) That an abundant supply of good grit is essential. 



(4) That Grouse driving is largely responsible for the 



increase. 



(5) That the limit has not necessarily been reached. 



(6) That the introduction of an artificial supply of water 



may be beneficial in a dry season or on the drier parts 

 of the moor. 



Cawdor Moor. 



A very fine moor not yet fully developed or arrived at its 

 full carrying power, with good young heather. The following 

 points in the record should be noted : 



(1) The improvement in each decade. 



(2) A slight set-back in 1890 to 1900, probably due to the 



moor being less well cared for during that period. 



(3) The period 1900 to 1910 shows a marked advance, owing 



to regular driving and improved methods of manage- 

 ment. 



(4) The time required for the moor to recover from the 



effect of the 1907 epidemic was one year ; on all 

 previous occasions it took upwards of four years to 

 get back to the average yield. 



This moor is in the centre of a Grouse-bearing district, 

 and will probably always be liable to disease from overcrowding 

 by birds from higher and less well-burnt moors in late winter 

 and early spring. This danger will remain until some system 

 is adopted for the proprietors taking joint action to regulate 

 the stock in good Grouse years. 



The bag in 1910 was 7,180| brace and in 1911 (a bad season 

 in the district) it was 3,443J brace. The moor is probably now 

 capable of yielding an average yearly bag of 5,000 brace as 

 compared to 600 brace in 1860 to 1870.
