A study of hadronic events with high jet-multiplicity is performed usi
ng the data sample collected by the L3 experiment at LEP at root s = 1
30-172 GeV. The observed event rates agree with the Standard Model pre
dictions and upper limits are set on the production cross section of p
airs of heavy particles that decay hadronically. (C) 1997 Elsevier Sci
