Inclusive production cross sections of $\pi^\pm$, $K^\pm$ and
$p\overline{p}$ in $e^+e^-$ annihilations are measured at a
center-of-mass energy of 10.54~GeV, using a relatively small sample of
very high quality data from the BaBar experiment at the PEP-II
$B$-factory at the SLAC National Accelerator Laboratory. The drift
chamber and Cherenkov detector provide clean samples of identified
$\pi^\pm$, $K^\pm$ and $p\overline{p}$ over a wide range of momenta.
Since the center-of-mass energy is below the threshold to produce a
$B\overline{B}$ pair, with $B$ a bottom-quark meson, these data
represent a pure $e^+e^- \rightarrow q\overline{q}$ sample with four
quark flavors, and are used to test QCD predictions and hadronization
models. Combined with measurements at other energies, in particular
at the $Z^0$ resonance, they also provide precise constraints on the
scaling properties of the hadronization process over a wide energy
range.
