Distinguish the Man of Words from the Man of Deeds. Discrimination here is as important as in the case of friends, persons, and employments, which have all many varieties. Bad words even without bad deeds are bad enough: good words with bad deeds are worse. One cannot dine off words, which are wind, nor off politeness, whichis but polite deceit. To catch birds with a mirror is the ideal snare. It is the vain alone who take their wages in windy words. Words should be the pledges of work, and, like pawn-tickets, have their market price. Trees that bear leaves but not fruit have usually no pith. Know them for what they are, of no use except for shade.
