Quark physics at multi-GeV electron beam accelerators.

We discuss the relevance of the explicit consideration of quark degrees of freedom for the understanding of experiments at multi-GeV electron accelerators such as the Continuous Electron Beam Accelerator Facility (CEBAF). We suggest that the precocious scaling'' seen in deep-inelastic scattering at low values of {ital Q}{sup 2} may be understood on the basis of a relativistic quark model which contains nonperturbative features not present in a quark-parton model. We also observe that the rate at which scaling is achieved is determined by a parameter which specifies the momentum content of the quark wave function of our model.
