  • In stamp collecting, a stamp cut or perforated into two parts, each half representing half the face value of the original stamp. Officially, authorized bisects have often been used during temporary shortages of commonly used denominations. Unauthorized bisects appear frequently on mail from some countries in some periods. Bisects are usually collected on full cover with the stamp tied by a cancel. At times, some countries have permitted trisects or quadrisects.

  • climbers tarry, stop

    then wait.

    cherried leaves lift, tilt, by chilled wind vibrate

    before soundless form and senseless weight.

    grey eyes ask and green reflect

    the shifting feet, distraught, caught

    rock and void, soil lost in puff and gasp and laugh bisect.

    hope is naught, closed lips don't see.

    growing gaping flying lost.

    moss is left, a life the cost.
