 sometimes very deadly. In swollen rivers of the 

 porter colour above mentioned some of the largest 

 takes have been made with stone-fly that ever were 

 made in the south of Scotland ; but it very seldom 

 happens that the porter-coloured river and an abun- 

 dance of stone-flies are to be met with in a state of 

 co-existence. The trout taken with this bait are 

 large and of the best quality better on the table than
