  We have searched for the pair production of first generation scalar
leptoquarks in the eejj channel using the full data set (123 pb-1) collected
with the D0 detector at the Fermilab Tevatron during 1992--1996. We observe no
candidates with an expected background of approximately 0.4 events. Comparing
the experimental 95% confidence level upper limit to theoretical calculations
of the cross section with the assumption of a 100% branching fraction to eq, we
set a lower limit on the mass of a first generation scalar leptoquark of 225
GeV/c^2. The results of this analysis rule out the interpretation of the excess
of high Q^2 events at HERA as leptoquarks which decay exclusively to eq.
