  We recall the main properties of inclusive particle distributions expected
for Pomeron-proton and Pomeron-Pomeron interactions. Due to the small size of
the Pomeron we expect larger transverse momenta of secondaries and a smaller
probability of Multiple Interactions, that is a narrower multiplicity
distribution. We propose to compare the spectra of secondaries produced in the
Pomeron and the proton interactions in terms of the Feynman $x_F$ variable. The
main difference should be observed for a relatively large $x_F$, that is near
the edge of rapidity gaps. Such data offer the opportunity to illuminate the
properties of the `soft' or `Regge' Pomeron, which drives the minimum-bias type
of events in high energy $pp$ interactions. Besides this, there should be a
good opportunity to observe a glueball in the Pomeron fragmentation region.
