  I discuss (i) hadron-hadron and photon-hadron total cross-sections, (ii)
elastic scattering, (iii) the r\^{o}le of minijets in total cross-sections and
the need to include them in Monte-Carlos for small-$x$ structure functions,
(iv) how the two pomerons affect small-$x$ behaviour, and (v) rapidity-gap
physics.
