The region around the double compact continuum source G35.2N has been mapped in J = 1-0 (C-12)O and J = 2-1 CS. High-velocity red and blue-shifted CO gas has been observed; both types show a very similar linear morphology centered on G35.2N. The results suggest a well-collimated bipolar outflow confined by the ambient molecular cloud and nearly orthogonal to the line of sight. The mass of high-velocity gas is about 60 solar masses; comparison with the HCO(+) observations of Matthews et al. (1984) suggests that the (HCO(+)/(C-12)O) abundance ratio must be enhanced in this gas by a factor of larger than about 20 compared with that expected for warm, dense clouds. A high-velocity stellar wind with a mass loss rate of roughly 8 x 10 to the -5th solar mass/yr is necessary to account for the outflowing gas.
