MY GARDEN. 



In a division of the order Neuroptera, and separated into the sub- 

 order Tricoptera, we have creatures of some importance to us, as they 

 afford abundant food for our trout. In the larva state (fig. io6oa) they

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

 state (fig. 1060 h) 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 hoVise (fig. 1061).
