WORM IN CLEAR WATER 85 



the green worm, but sight surely is the sense 

 utilised more than smell in low, clear water. 

 Besides, fishes' sense of smell seems to us 

 still to remain an 'unknown quantity,' and 

 as yet unproved. 



It is unnecessary to recapitulate the ad- 

 vantages of up-stream fishing with worm. 

 Nothing can be added to that part of the 

 subject beyond Stewart's directions for prac- 

 tice. But when we come to speak of when 

 to expect sport, while his directions and 

 facts are in most cases incontrovertible, we 

 think there has been left some room for 

 deductions as to the ' whys ' and ' wherefores ' 

 of good and bad conditions, and we propose 

 in the next chapter to explain some of these 

 matters of inquiry.
