  We use ISAJET to perform a detailed study of the missing transverse energy
$\eslt$ plus multi-jet signal expected from superparticle production at the
CERN LHC. Our analysis is performed within the framework of the minimal
supergravity model with gauge coupling unification and radiative electroweak
symmetry breaking. We delineate the region of parameter space where the $\eslt$
supersymmetry signal should be observable at the LHC and compare it to the
regions explorable via searches for sleptons and for chargino/neutralino
production. We confirm that, given a data sample of 10~$\fb^{-1}$, $m_{\tg}\sim
1300$ GeV can be explored if $m_{\tq}\gg m_{\tg}$, while $m_{\tg}\sim 2000$ GeV
can be probed if $m_{\tq}\simeq m_{\tg}$. We further examine what information
can be gleaned from scrutinizing this event sample. For instance, the multi-jet
multiplicity yields information on whether squark production makes a
significant contribution to the observed $\eslt$ sample. Furthermore,
reconstructing hemispheric masses may yield a measure of $m_{\tg}$ to $\sim
15-25\%$. Finally, for favourable ranges of parameters, by reconstructing
masses of tagged $b\bar{b}$ jet pairs, it may be possible to detect Higgs
bosons produced via sparticle cascade decay chains.
