He once said, «  The only use of books is to instruct you in the meaning of a name. Your own eyes and ears and touch must teach you the nature of things. »

« Did you ever see a caddis worm ? When I wasfishing I never could stick a book into a caddisworm. » (a case worm, the larval stage of a caddis fly- a trichopterous neuropterous insect, like a phryganied). «  I never contemplate a caddis worm without a certain feeling of brotherhood. Nature is essentially too satirical in the way she takes off one thing when she design another.

Everyone has, by nature, the faculty of picking up bits  wherewith to furnish himself according to the ground he is upon at the time, as the caddis worm dresses her self in scraps of green when she is upon the leaves, and in bits of brown when upon the stones.

Don’t despise the simile and think it rough. Don’t say to me, «  Everything has both its higher and its lower paralleles ; why should be tempted to reply. «  To keep us down at our proper level. O brother worms. »
