98 THE GROUSE 



upon the average period occupied from 

 the year of burning to mature regrowth 

 on any particular moor. The yearly 

 extent on any single moor or estate to 

 which heather burning may be safely 

 carried may greatly exceed that which 

 may be properly practised on another. 

 Here again soil, climate, and other 

 elements enter into the problem. Where 

 a rule or standard must be laid down 

 in leases, a fair proportion frequently 

 adopted is one-tenth every year of all 

 aged, dead, or decaying heather, which of 

 course is not commensurate with the 

 same proportion of all heather and much 

 less than all the ground of the farm or 

 moor. Not infrequently it proves to be 

 more than can be overtaken, owing to 

 unsuitable weather, even when the burn- 

 ing season is extended from the 11th to 

 25th April ; but it is usual on most 

 estates when this occurs to allow in 

 the succeeding year a further extent, 

 equivalent to the shortcome of stipulated 

 burning in the previous year.
