    We propose to detect hard X-ray emission from deeply embedded proto-
    star candidates associated with Taurus Morecular Cloud 1. ASCA provid
    eds a unique opportunity to observe the surface region of embedded
    protostars by virtue of its high imaging capability in the hard X-ray
    band where radiation is transparent to gas clouds with visual extinc-
    tion more than 100 magnitudes. We selected the TMC 1 region for the
    target of the propossed observation because 3 protostar candidates
    are located within the GIS field of view in this dark cloud, with
    enough separation from each other X-ray emission , which is feasible
    with the high sensitivity of ASCA, leads us first to understand the
    physics of protostellar surface activities, especially those related
   with magnetic fields.
