  Strange baryons have long been known to exhibit a leading particle effect. A
recent comparison of $\Xi^-$ production in $\pi^-$, $n$, and $\Sigma^-$
interactions with nuclei show this effect clearly. These data are supplemented
by earlier measurements of $\Xi^-$ and $\Omega$ production by a $\Xi^-$ beam.
We calculate the $\Xi^-$ and $\Omega$ $x_F$ distributions and nuclear
dependence in $hA$ interactions using the intrinsic model.
