312 LETTERS TO YOUNG SHOOTERS LETTER 



be concealed, it is therefore always advisable it should 

 be utilised to hide the guns from the birds in an 

 upwind drive ; but should there be a suitable ridge 

 that will answer for the downwind drive, and another 

 a little way off that will serve for the upwind one, 

 ill en erect two lines of shelters, and drive the birds 

 first over the one line and back again over the other. 



The number of shelters necessary will entirely 

 depend upon the acreage of a moor and its forma- 

 tion. 



If a moor consists of several wide flats, each flat 

 will require its long line of shelters. Eight guns are 

 generally sufficient, though, for any moor, whatever 

 its size. When a moor has a good deal of high or 

 broken ground, interspersed with narrow 7 valleys, then 

 a less number of shelters will be requisite for the 

 different drives, and you cannot, as a result, find 

 sport for so many friends, unless you arrange tw r o 

 lines of shelters, one a hundred yards or so before 

 the other, an unpleasant practice, and liable to be a 

 dangerous one, save the shooters are very careful how 

 they fire. Though a moor on which the grouse have 

 to be driven through narrow passes will not supply 

 shooting for the usual eight guns, it may, nevertheless, 

 afford excellent sport to four or five ; as the more 

 confined the space within which the birds can be driven
