1. A device for emitting two or more volatile compositions, wherein said device comprises two or more different volatile compositions comprising at least a first volatile composition and a second volatile composition, and wherein said device comprises a heater and wick, said heater and wick are configured to emit said first and second volatile compositions through said wick, and further, wherein said device comprises a timing mechanism configured to emit said first and second volatile compositions in a substantially continuous emission sequence in which the emission of the different volatile compositions automatically alternates between the different volatile compositions in the sequence, wherein in said alternating sequence:

  • (a) said first volatile composition is emitted for a first time period, said first time period having a beginning and an end;

    (b) said second volatile composition is emitted for a second time period, said second time period having a beginning and an end, and said second time period begins at one of the following times;

    (i) at the end of said first period;

    or(ii) after a period of time comprising a gap period after the end of said first period; and

    (c) after the beginning of said second period, said first volatile composition is emitted again, and the pattern repeats;

    wherein said different volatile compositions are emitted during discrete emission periods, said discrete emission periods are each from 23⅓

    minutes to less than 120 minutes in length.
