The extended infrared emission from dust around the L1551 flow and the extended and small scale infrared emission from the Serpens nebula are analyzed using IRAS data. The extended infrared emission from the L1551 flow has an infrared bolometric luminosity greater than 20 Lo. Ultraviolet radiation appears to heat the dust surrounding the flow. The infrared emission raises the total energy requirement over a 100,000 yr lifetime by 2 orders of magnitude to 10 to the 46 to 47th ergs. In all four IRAS bands the Serpens nebula exhibits infrared emission over a scale of a degree around three stars of spectral class B and A. The stars appear to lie near an interface region. The infrared emission from the central 12 arcmin portion of the nebula correlates well with ammonia.
