The methodology of CDF and D0 top quark analyses and their
underlying assumptions are summarized.  The CDF and D0 top mass averages,
obtained from measurements in several channels and based on about 100 pb-1
of data from p anti-p collisions at s**(1/2) = 1.8 TeV collected by each
experiment in Run-I, are: M_t = 176.1 +/- 4.0(stat) +/- 5.1(syst) GeV/c2
and M_t = 172.1 +/- 5.2(stat) +/- 4.9(syst) GeV/c2, respectively.  The
combined Tevatron measurement of the top quark mass is M_t = 174.3 +/-
3.2(stat) +/- 4.0(syst) GeV/c2.  The CDF measurement of the tt-bar cross
section (assuming M_t = 175 GeV/c2) is sigma_tt = 6.5 +/- 1.6_1.4 pb, and
the D0 value(assuming M_t = 172.1 GeV/c2) is sigma_tt = 5.9 +/- 1.7 pb.  In
anticipation of much larger statistics, prospects for top physics in
Tevatron Run-II are summarized.  The fact that top quark analyses are among
the best windows to physics beyond the Standard Model is emphasized.
