Results are presented of a search for pair production of heavy objects decaying into four hadronic jets, as expected for example from associated or pair production of MSSM Higgs bosons, \hA ~or \HH, using a data sample of $5.9\;$pb$^{-1}$ of $e^+ e^-$ collisions at $\sqrt{s}=130-136\;{\mathrm {GeV}}$ collected with the DELPHI detector at LEP in November 1995. The data and expectations from standard processes agree after four-jet selections. An analysis based on $b$-tagging finds no \hA ~candidate with high mass. A study optimized to search for \HH ~events with mass in the $40-50 \; {\mathrm{GeV}}/c^2$ range also finds no candidate. Finally a comparison is made with a recent ALEPH analysis which found an excess of four-jet events with high m...
