On finding these insects in the trout I 

 took some of them home, and made imita- 

 tions of them. With these the next day 

 I caught a number of trout, though the 

 weather was just as unfavourable. Since 

 then I have improved somewhat upon the 

 imitations I then used, and in waters 

 which are inhabited by Oorixse. These 

 imitations have met, both in my hands 

 and in the hands of others, with greater 

 success than any other form of wet fly. 



It is an extraordinary thing, considering 

 the number of men who have written on 

 trout fishing, that it has apparently never 

 occurred to one of them to describe an imi- 

 tation of one of this large family of insects. 

 Mr. Halford, in his Dry-fly Entomology, 

 indeed states that he has frequently found 

 them in the stomachs of trout, but he does 

 not even suggest that an imitation of them 

 might be made. 



There are many species of Oorixse which 

 inhabit our waters, but the commoner sorts 

 are so similar in appearance that many of 

 the species are very difficult to distinguish 

 even by an expert, and but little work has 

 been done with regard to them. Therefore
