We present a locally N=1 supersymmetric model of the dilaton {phi} and the two-form tensor (axion) B{sub {mu}}{sub {nu}} as compensators without propagation. This is a generalization of our previous model with global N=1 supersymmetry to local N=1 supersymmetry. The dilaton {phi} and the axion B{sub {mu}}{sub {nu}} are, respectively, absorbed into the vector A{sub {mu}} and the three-form tensor C{sub {mu}}{sub {nu}}{sub {rho}}, where the latter is dual to the ordinary auxiliary field D in the usual vector multiplet. With local N=1 supersymmetry, we have three multiplets: the multiplet of supergravity (e{sub {mu}}{sup m},{psi}{sub {mu}}), linear multiplet (B{sub {mu}}{sub {nu}},{chi},{phi}), and the vector multiplet (A{sub {mu}},{lambda},C{sub {mu}}{sub {nu}}{sub {rho}}). We find that the field strengths of B and C need the following particular Chern-Simons terms for consistency with local supersymmetry: G{identical_to}3dB-6BD{phi}+3mBA+mC and H=4dC-6BF+4GA+8CD{phi}-4mCA. The newly established supergravity couplings provide the supporting evidence of the consistency of our basic system of the dilaton and axion as compensators.
