  We have used the SHARP polarimeter at the Caltech Submillimeter Observatory
to map the polarization at wavelengths of 350 and 450 micron in a ~2 x 3 arcmin
region of the Orion Molecular Cloud. The map covers the brightest region of the
OMC-1 ridge including the Kleinmann-Low (KL) nebula and the submillimeter
source Orion-south. The ratio of 450-to-350 micron polarization is ~ 1.3 +/-
0.3 in the outer parts of the cloud and drops by a factor of 2 towards KL. The
outer cloud ratio is consistent with measurements in other clouds at similar
wavelengths and confirms previous measurements placing the minimum of the
polarization ratio in dusty molecular clouds at a wavelength ~ 350 micron.
