 afford abundant food for our trout. In the larva state they live in the 

 water, and are then called Caddis-worms ; in the perfect state they

become winged creatures, and in both conditions are eagerly devoured 

 by trout. In the larva state they live in a beautiful house, which they 

 construct themselves of little bits of sticks, shells, or other materials, 

 which they select according to the force of the stream in which they 

 reside.

My daughter was so much interested in watching these creatures in 

 their strange houses, as they moved along the bottom of the little 

 streams, that a number were procured for more exact observation. The 

 caddis-worms were turned out of their dwellings, and each was placed 

 in a separate glass of water, with various materials suitable for the 

 construction of their house, when the nude creature immediately set 

 to work to make a new house, and never stopped till the greater part 

 of its body was encased (Fig. 1061).
