Great events, says the philosophic historian, spring only from great causes, though the immediate occasion may be small; but I think his law must have exceptions. Of the not inconsiderable events which I am about to chronicle, the occasion was trivial, and I find it hard to detect the majestic agency 
behind them. What world-force, for example, ordained that Mr Dickson McCunn should slip into the Tod's Hole in his little salmon-river on a bleak night in April; and, without changing his clothes, should thereafter make a tour of inspection of his young lambs? His action was the proximate cause of this tale, but I can see no profounder explanation of it than the inherent perversity of man.
