\subsection{CS Mapping}  The three mapped regions are shown as boxes overlaid on the GLIMPSE 8 $\mu$m images in Figures \ref{N56map}-\ref{N77map}. The maps were cropped to just those regions showing emission above 3$\sigma$. The regions containing emission were then exported to a FITS file using custom-built IDL tools {\bf and the FITS-format datacubes were analyzed} using CASA. The standard moment maps (total intensity, average velocity and velocity width) are shown next to the corresponding 8 $\mu$m emission images in Figures \ref{N56map}-\ref{N77map}.  The three maps of CS in N56, N65, and N77 (Figs. \ref{N56map}-\ref{N77map}) show evidence of supersonic gas motion in areas near each YSO. N56 has a weak peak in CS that corresponds to a velocity shift of $\sim$2 km/s in the gas immediately to the north. {\bf The CS emission in N65 has a clear, strong comma-like shape.} The peak in emission is clearly near the top of the shape, but there is a slight, secondary peak below and to the right in Fig 3b. There is also a shift in gas velocity of $\sim$1 km/s at the same location. {\bf Two spectra from the map, centered at the primary and secondary peaks, are shown in Figs. 3e and f. The spectrum at the primary peak shows two components, with the red-shifted component stronger. At the secondary peak, this component appears to shift further redward.} We interpret the secondary peak, shift in first-moment map and the double-Gaussian peak from single pointing spectra as all caused by {\bf at least} two overlapping clouds at different velocities. {\bf Using this interpretation, the emission peak seen in Fig. 3b is coincident with the blue-shifted gas shown in Fig. 3c because emission from the bluer cloud is not present at the location of the pointing shown in Fig. 3f.  There may be futher motion within each cloud, which could be responsible for the redward shift of the stronger component.} The least distinct of the regions, N77 shows weak emission with some evidence of shifts in velocity of $\sim$1 km/s. These shifts could be caused by several mechanics: outflow from or infall toward the YSO or shock-induced velocity shifts caused by the expanding HII region. The limited nature of the data prevents an exclusive interpretation.
