We have surveyed two 1.7 square degree sections of the galactic plane at 70 ..mu..m with one-arcminute resolution. The scanned areas included the giant southern H II region complexes NGC 6357 and NGC 6334. Nineteen far-infrared sources were observed. The sources range in luminosity from 1.6 x 10/sup 4/ to 5.5 x 10/sup 5/ L/sub sun/ . We present far-infrared continuum and CO line observations of NGC 6357. Four far-infrared sources were found in this complex and for one of these sources the exciting stars are identified. We present far-infrared and CO observations of sources in the field surrounding NGC 6357 and NGC 6334. The far-infrared sources coincide frequently with CO line temperature peaks. The CO clouds which surround the far-infrared sources have similar /sup 13/CO column densities. Two of the far-infrared sources in the field have associated OH and H/sub 2/O maser emission and compact H II regions.
