Luminosities are determined, for embedded sources found in the course of mapping areas on the order of 20 x 30 arcmin in the molecular clouds associated with NGC 2071, Mon R2, ON 1, and IC 5146 at 85 and 150 microns. The energetics of each cloud are also examined, and it is found that external sources may contribute to the extended far-IR emission from these clouds. The observations indicate that radio-quiet, protostellar sources have much less effect on the observed temperature structure of star-forming clouds than do objects of comparable luminosity which have already formed compact H II regions, and that the radio-quiet sources appear to be more deeply embedded than those now associated with ionized gas. It is proposed that massive stars may form deep within molecular clouds rather than only at their surfaces.
