  We have studied the $e^+ e^- \to Z \phi_i \to Z jj$ process, where $\phi_i$
is the Higgs and/or radion bosons. The implications of the radion effects on
the preliminary ALEPH data are also discussed. The case of the lighter radion
than Higgs boson is disfavored by the ALEPH analyses of the $b$ tagged four-jet
data, since the radion predominantly decays into two gluon jets due to the QCD
trace anomaly. If the radion is highly degenerate in mass with the Higgs, the
cross section can be increased more than at one sigma level, with natural scale
of the vacuum expectation value of the radion.
