particles of sand agglutinated together, as I have before 

 mentioned ; and from them issue the different tribes of 

 duns, yellows, etc. all purely aquatic flies, and lures of 

 the first excellence for trout. 



These caddies may easily be procured in their re- 

 spective seasons before they assume the winged state

 in May by searching the small rills and wet ditches 

 which adjoin the rivers, when they will be found crawl-

They may be preserved for use in several different 

 ways. One method is, to put them into a linen bag for 

 five or six days, and dip it and its contents into water 

 once a day and hang them up in a cool place ; when they 

 will become tough, yellow, and fitter for use than when

 them into a thick woollen bag, along with some sand

 when they will live and thrive until transformed into
