THE DRY-FLY SEASON 209 



welcoming the floating banquet and have learned 

 to expect it. The day must necessarily be cold 

 indeed if the hardy Iron Blue is not seen sailing 

 down the pool and bringing up the trout to inspect. 



If, on the contrary, the sun streams fiercely 

 down, let it be remembered that it beats also upon 

 the sandbeds, wherein lurk the young sandflies 

 waiting and wearying for its coming. Over the 

 sand they gaily sport, and a puff of wind, a mere 

 breath, comes along, blowing them on the water, 

 where await the trout longing for such great deli- 

 cacies, and the angler must be there to reap the 

 harvest. 



Even sometimes another race of flies which love 

 the gloaming will be born anew, and so the day 

 may be prolonged into the night. 



On the river the flies that may be expected 

 are numerous, too numerous we might almost 

 say, but the variations in size and coloration 

 are so exceedingly minute that not all are worthy 

 of imitation. Perhaps the time may yet come 

 when the education of the trout will reach such 

 a state of perfection that it will be necessary to 

 attend to every detail, but the day is not yet. 

 Greenwell Quill, Medium Olive, Iron Blue will 

 on most waters be sufficient, but the sand-fly is 

 indispensable on those streams which rejoice in 

 the environment necessary to its development. 

 It may be plentiful on some reaches of a river 

 and altogether absent from others, the nature 

 of the bank being the determining factor. The 

 Grannom or Greentail is also due, and on suit- 

 able evenings a floating Red Quill will account 

 for many trout.
