  The possibility of exploring the systematics of the spectroscopy, strong
dynamics, and the weak and rare decay modes of b--quark systems at hadron
colliders such as Fermilab, LHC and SSC, is discussed. A copious yield of
$10^{10}$ detected $B$--mesons is readily accessible in a dedicated Fermilab
program, and implies a vast array of accessible decay modes, including second
order weak processes and $CP$--violation, which will be unavailable elsewhere
until the commissioning of LHC or SSC. Kinematic and flavor tagging, utilizing
the ``daughter pions'' from resonances, is expected to play a major role in
semileptonic weak decay studies and the search for $CP$--violation. Plenary
talk, Workshop on $B$ Physics at Hadron Accelerators, Snowmass, Colorado, June
25, 1993; Invited Lecture, TASI, Boulder, Colorado, June 18, 1993.
