loo RECREATIONS OF A NATURALIST 



From independent observation we are inclined ta 

 believe that the supply of drinking water may have 

 something to do with it. Grouse, like other game 

 birds, must have water, and so long as they can drink 

 from the burns or the little rills of pure water that 

 trickle down the hillsides all goes well ; but should 

 there come a dry summer, when the running water 

 fails, they are obliged to have recourse to the small 

 stagnant pools on the low ground, which may 

 produce a species of typhoid comparable to that 

 which attacks our troops on the march when 

 compelled to drink unwholesome water. To 

 substantiate this view it would be desirable to 

 ascertain whether the outbreaks of Grouse disease 

 have invariably occurred when the moors have beea 

 in this waterless condition.
