  We present results from the measurement of the inclusive jet cross section
for jet transverse energies from 40 to 465 GeV in the pseudo-rapidity range
$0.1<|\eta|<0.7$. The results are based on 87 $pb^{-1}$ of data collected by
the CDF collaboration at the Fermilab Tevatron Collider. The data are
consistent with previously published results. The data are also consistent with
QCD predictions given the flexibility allowed from current knowledge of the
proton parton distributions. We develop a new procedure for ranking the
agreement of the parton distributions with data and find that the data are best
described by QCD predictions using the parton distribution functions which have
a large gluon contribution at high $E_T$ (CTEQ4HJ).
