Query: On the structure of continua with finite length and Golab's
  semicontinuity theorem   The main results in this note concern the characterization of the length of
continua 1 (Theorems 2.5) and the parametrization of continua with finite
length (Theorem 4.4). Using these results we give two independent and
relatively elementary proofs of Golab's semicontinuity theorem.
