                Even reckoning makes lasting friends, and the
                way to make reckonings even is to make them
                often.                            --South.

                He quitted London, never to return till the day
                of a terrible and memorable reckoning had
                arrived.                          --Macaulay.

   2. The charge or account made by a host at an inn.

            A coin would have a nobler use than to pay a
            reckoning.                            --Addison.

   3. Esteem; account; estimation.

            You make no further reckoning of it [beauty] than of
            an outward fading benefit nature bestowed. --Sir P.
