We use new measurements of the inclusive electroproduction reactions e + N --> e' + pią + X and e + N --> e' + p + X with epsilon values in the range 0.35 < epsilon < 0.45 together with earlier measurements with 0.85 < epsilon < 0.95 to determine the contributions to the cross section due to transversely and longitudinally polarized photons in the range 1.2 GeV^2 < Q^2 < 3.3 GeV^2. The longitudinal component is small and consistent with that observed in the total virtual-photoproduction cross section.
