The analysis of the data from our 48k photo 205 GeV π^⁻p exposure of the bare 30-inch hydrogen bubble chamber (Experiment No. 137) has pointed up the desirability of another run at substantially higher energy. We therefore request another exposure in the same chamber of at least comparable statistics (50K photos) at approximately double the beam momentum. We estimate that with 460 GeV accelerated protons we can get a sufficient flux of 400 GeV π^⁻. Details are given in the appended note. Such an exposure should produce some 800 elastic scatters and about 6000 inelastic events from which one can measure total and elastic cross sections, and study multiplicity distributions, diffractive processes, strange particle production, inclusive distributions and gross characteristics of copiously produced channels.
