  Photoproduction data collected with the H1 detector at HERA in 1994 are used
to study the cross-sections for inclusive charged particle production and the
structure of the photon. The differential cross-sections dsigma/dpT2, for |eta|
< 1 in the HERA laboratory frame, and dsigma/deta for pT > 2 GeV/c and pT > 3
GeV/c have been measured. Model calculations of these cross-sections, based on
perturbative QCD, indicate that the results are sensitive to the parton
densities of the photon as well as to higher order effects, which are
phenomenologically treated by multiple interactions. This sensitivity is
exploited to determine the leading order x_gamma distribution of partons in the
photon using a new method based on high pT charged particles. The gluon content
of the photon is extracted and found to rise with decreasing x_gamma.
