 large to ensure its being seen, but not large enough 

 to allow the trout to detect its artificiality. To

 lochs must be provided with all sizes of flies from 

 No. 10 up to No. 3. 



The colour of the water and the amount of wind

 than when it is clear. If there is a strong breeze of 

 wind blowing, a size or two larger may be used than 

 when there is little wind; and when there is no
