We report on the performance of the CDF End Plug Hadron Calorimeter
in a test beam.  The sampling calorimeter is constructed using 2 inch iron
absorber plates and scintillator planes with wavelength shifting fibers for
readout.  The linearity and energy resolution of the calorimeter response to
pions, and the transverse uniformity of the response to muons and pions are
presented.  The parameter e/h, representing the ratio of the electromagnetic
to hadronic response, is extracted from the data.
