The silken threads by viewless spinners spun, br Which float so idly on the summer air, br And help to make each summer morning fair, br Shining like silver in the summer sun, br Are caught by wayward breezes, one by one, br Are blown to east and west and fastened there, br Weaving on all the roads their sudden snare. br No sign which road doth safest, freest run, br The wingèd insects know, that soar so gay br To meet their death upon each summer day.
