We report on inclusive hadron production in e/sup +/e/sup -/ annihilation at < s < or = = 53 GeV/sup 2/, using a small solid-angle magnetic spectrometer with good particle identification at 90/sup 0/ to the beams at SPEAR II. The cross sections of ..pi../sup + -/ and K/sup + -/ when compared with data at s = 23 GeV/sup 2/ exhibit scaling in (s/..beta..) dsigma/dx with x = 2E/s/sup 1/2/. The invariant cross section depends on the momentum as p/sup -4/.
