306 LETTERS TO YOUNG SHOOTERS LETTER 



over the boundary, and from not being able to shoot 

 certain parts of the naoor lest they should in this 

 way escape the guns. 



The outline of a moor that is suitable for grouse 

 driving should be as square as possible, so that, by 

 selecting a line of shelters, according to the wind, you 

 may drive it in almost any direction without sending 

 its birds over the march. This does not at all neces- 

 sitate a very large acreage, but it implies a moor 

 that is not narrow, and does not run here and there 

 into long points. 



The perfection of a driving moor is one of the 

 same average elevation, and containing several broad 

 level valleys pointing south-west, so as to obtain the 

 assistance of the prevailing winds for driving the birds, 

 with low heather-clad hills, alternating with wide flat 

 tracts of land, and long smooth slopes. You can do 

 as you like with grouse when driving them under 

 these conditions. 



We cannot arrange the hills and valleys to suit 

 our wishes, but at the same, time select a driving 

 moor as near as you can to the above description, 

 or even a moor that you wish to introduce grouse 

 driving on after its birds are too wild for your 

 pointers and setters.
