WATER INSECTS AND THE RISE 73 



fly on the water, he will be well advised to substitute 

 any other of the flies thus grouped together. 



Looking back over many years of trout fly fishing, it 

 appears to me that though each district, or even the different 

 rivers in each district, may have its own special order in 

 the appearance of the metamorphosis of the aqueous life 

 of its water insects into their flying state, yet the order 

 in which I have placed the artificial flies will be found to 

 have a fairly general application, and to be somewhat 

 in the order in which these flying insects will appear, 

 although some of them will be taken throughout the fishing 

 season. 



There are districts in which certain flies are successful 

 at all times of the year, and for this reason it is advisable 

 to avail oneself where possible of the experience of the local 

 fishermen. 



A certain fly may appear by the water side at an earlier 

 or later date than usual, but it does not follow that at 

 their first hatch such flies will be taken by the trout, 

 or indeed until some weeks have elapsed after their first 

 appearance. 



Any of the above flies may be useful for dry fly fishing 

 on lochs, etc. For wet fly fishing on lochs the flies locally 

 used and tied on gut can nearly always be obtained. 



If you intend fishing in any particular district, you 

 should, when stocking your fly case, commence with the 

 flies which are recognized killers on the rivers, streams and 

 lochs which you are going to fish. 



If, however, your fishing is likely to be extensive, and 

 you are to visit different parts of the United Kingdom, then 

 it will be well to stock all the flies in the list I have given, 

 and arrange your small fly box daily. 



Were I dependent on say twenty different flies, I 

 should choose the following varieties :
