From the trees spun down The canker- worms upon the passers- by, Upon each woman's bonnet, shawl, and gown, Who shook them off with just a little cry They were the terror of each favorite walk, The endless theme of all the village talk.- "The Complete Poetical Works of Henry Wadsworth Longfellow", Henry Wadsworth Longfellow.
