  We present new imaging and spectroscopic observations of the interacting
system Arp 194 (= UGC 06945 = VV 126). The northern component (A194N) is a
distorted spiral or ring galaxy likely disrupted by a collision or close
encounter with a southern galaxy (A194S). There is evidence that a third galaxy
with similar recession velocity is projected on A194N but its role is likely
secondary. A194S is connected to A194N by a string of emission knots which
motivates our interpretation that the former was the intruder. Three of the
knots are easily discernible in B,R, and H-alpha images and are assumed to
trace the path of the intruder following the encounter, which we estimate
occurred a few 10^8 yr ago.
  Both A194S and N are experiencing strong bursts of star formation: the
H-alpha luminosity indicates a total star formation rate ~ 10 solar masses per
year. The lack of detectable J and K emission from the blobs, along with strong
H-alpha emission, indicates that an evolved stellar population is not likely to
be present. The brightest knot (closest to A194S) shows a star formation rate
of ~1.2 solar masses per year which, if sustained over a time ~ 7 10^7 yr,
could explain the spectral energy distribution. This suggests that the stripped
matter was originally predominantly gaseous. The brightest knot is detected as
a FIRST radio source and this is likely the signature of supernova remnants
related to enhanced star formation. Motions in the gas between the brightest
knot and A194S, traced by an emission line link of increasing radial velocity,
suggests infall toward the center of the intruder. Arp 194 is therefore one of
the few galaxies where evidence of ``cross-fueling'' is observed [LaTeX
