Measurements of the dependence on $s={(p_a+p_b)}^2$ of the cross sections for production of single charged hadrons in the reactions $a+b\to c+\mathrm{anything}$ are presented. Particle $c$ was detected in a fixed interval of laboratory momentum and angle in the fragmentation region of the target proton. The ${\pi }^{\pm }$ and $K^{+}$ production data are consistent with the Mueller-Regge prediction of an approach to scaling as $A+B{s}^{-\frac{1}{2}}$. Further tests of a simple Regge-pole model indicate that the $s$ dependence measured is fortuitous, and that higher-energy data are required in order to make detailed tests of the model.
