 for each warble contains a grub, and there is a perfora- 

 tion of the skin immediately above the warble. It 

 is highly probable that a careful study of parasites, 

 accompanied by special knowledge, would result in 

 discoveries sufficiently important to warrant great 

 alterations in the management of sheep and deer, 

 which might eventually lead to the permanent 

 reduction of the present heavy death-rate prevailing 

 amongst these animals. Mr. Evans is confident that 

 burning considerable tracts of heather almost entirely 

 checks parasite mischief ; but of course there must be 

 a limit to this remedy, as in burnt ground there is 

 hardly any feeding for the first winter after burning, 

 and, therefore, good judgment as to where and how 

 much to burn is essential to the success of this plan. 



That the mortality in all deer forests is heavy 

 may be taken for granted, the following having been 

 the death-rate in Jura, which, from its position, should 

 be better off in this respect than the forests of the 

 mainland : —
