Earlier workshops~\cite{tev2k,tev33} and this study have
identified the reactions $\pp\rightarrow WH\rightarrow l\nu\bb$ and
$\pp\rightarrow ZH\rightarrow \nn\bb$ as likely modes for discovering the
Higgs boson at the Tevatron.  However, the great majority of events
from the associated production modes $\pp\rightarrow WH$ and
$\pp\rightarrow ZH$ do not give final states in these channels.
Roughly 70\% of the final states arise from events in which the $W$ or
$Z$ has decayed hadronically.  These modes result in a four-jet final
state with two jets from the vector boson decay and two $b$ quark
jets from the Higgs decay.  Moreover, the same $\qq\bb$ final
state arises in the vector boson fusion process: $\qq\to VV +
\qq \to H + \qq$ ($V=W$, $Z$) when $H\to \bb$, the
dominant Higgs decay mode for $m_H\lsim 135$~GeV.  In the case of
$VV$ fusion, because there are two forward jets originating from the
$\qq$ in the final state, one may hope to be able to suppress the
Standard Model backgrounds by appropriate cuts.  Three analyses of
this final state are presented here.  The first is an extrapolation of
a published CDF Run~1 analysis and the second is a prototype analysis
using a combination of SHW and data.  These studies focus on the
$\qq\bb$ final state that arises in $WH$ and $ZH$ production.  The
third is a feasibility study of the vector boson fusion process and is
based on a parton-level Monte Carlo analysis.
