Abstract: Arcs (linearly ordered continua) $ A$ and $ B$ are constructed such that every map from $ A$ to $ B$ and every map from $ B$ to $ A$ is constant. The Generalized Continuum Hypothesis is sufficient for the existence of two such arcs each of cardinality $ {2^\aleph }$ for each uncountable cardinal $ \aleph $.
