Caroline Alathea Stickney Creevey, At random, New York, G.P. Putnam’s, 1920, p. 199.

I was examining water plants. One seemed to have fruit on the stem instead of on the tips of branches, where it ought to be. Placing it under my magnifying glass, I saw that it. Was the case of a small caddis worm, made of tiniest bits of sticks, caught together at one end and sticking out in all directions. There was a certain regularity in the arrangement of the sticks that reminded me of the clothespin houses that i used to make when a child.I carefully cut off the end of this case, and exposed the head and body of an almost transparent larva, which distincly palpitated under my gaze.
