Optical and infrared polarimetry of sources in the direction of the Taurus cloud are obtained in order to study the magnetic field in this cloud and its possible role in the cloud's evolution. Most of the stars are background giant stars whose light shines through the cloud and is polarized by the cloud material. The transverse component of the magnetic field, as delineated by the polarization vectors, is generally perpendicular to the galactic plane, and the stratified structure of the cloud could be due to the effect of the magnetic field during the early stages of collapse. Three of the 13 embedded stars are strongly polarized with position angles nearly perpendicular to those of nearby field stars. The polarization of these stars is most likely intrinsic, and the direction of polarization indicates that the material surrounding these stars may be magnetic i.e., that the magnetic field is frozen in this material.
