48 FISHERMAN'S LURES 



I do not advocate the use of them as live bait, 

 because it is more to the fisherman's interest to 

 leave them to breed and multiply solely for trout 

 food. If, however, we make our artificials suffice, 

 we shall not rob the trout or other fish of their 

 natural diet, which robbery, if carried to excess, 

 will result in there being no trout to capture. How- 

 ever plentifully the rivers are stocked, trout must 

 be supplied with food to grow and become more 

 abundant. This truism I repeat constantly, yet 

 not too often. 



Caddis-flies are classed under the general head 

 of "Duns" (trichoptera), which includes a large 

 variety of species that may be placed in two well- 

 defined families. The first consists of those larvae 

 which make portable cases which they drag around 

 with them wherever they go, of which the insect 

 I name "Cinnamon," in Trout Stream Insects, is 

 one of the largest species, and is here illustrated. 

 The other class is composed of those larvae making 

 fixed cases, generally attached to large stones, 

 from which they issue in quest of food, and to 

 which they return for rest. Each of these two 

 divisions furnishes a vast quantity of bottom 

 food for trout, which they eagerly devour, both 

 creeper and case, as I have proved by many un-
