418 THE GROUSE IN HEALTH AND IN DISEASE 



No figures relating to the breeding stocks on these moors 

 are available, but judging from the bags the following deduc- 

 tions may be made : 



No. 1 Moor. Three hundred to four hundred pair of birds 

 appears to be the limit of stock the ground would carry in 

 March. It will be noted that every time the bag exceeds one 

 thousand brace disaster follows. 



No. 2 Moor. An improving moor apparently able to carry 

 three hundred to five hundred pairs of March stock in a normal 

 year. 



No. 3 Moor. A very typical dogging moor with four hundred 

 pairs of breeding stock a safe limit. 



No. 4 Moor. A small well-burned moor note the rapid 

 recovery from disease ; also that it is dangerous to approach 

 five hundred pairs of breeding stock. 



No. 5a and 5b Moors. The records begin with the year 

 18C6, and the disastrous character of the outbreaks in 1867 

 and 1873 are reflected in the bags. 1 The figures in column 5a
