Static electrical and magnetic properties of single crystal BaVS3 were measured over the structural (TS=240K), metal insulator (TMI=69K), and suspected orbital ordering (TX=30K) transitions. The resistivity is almost isotropic both in the metallic and insulating states. An anomaly in the magnetic anisotropy at TX signals a phase transition to an ordered low-T state. The results are interpreted in terms of orbital ordering and spin pairing within the lowest crystal-field quasidoublet. The disordered insulator at TX<T<TMI is described as a classical liquid of nonmagnetic pairs.
