A description of the existing experimental data on inclusive spectra of $D_s$ - mesons production in $πp$ - collision and asymmetry of leading ($D_s^-$) and nonleading ($D_s^+$) mesons in $Σ^- p$-- interaction is obtained. The predictions for cross sections and leading/nonleading asymmetry in $πp$ - and $Σ^- p$-- collision for different initial momenta are also given.Latex, 9 pages, 10 figs. tar, gzip Submitted to Phys.
