  I present some comments on the partonic interpretation of the HERA data on
the proton structure function. The effects of the resummation of the leading
and next-to-leading $\ln x$-contributions are discussed. A new factorization
scheme, in which these resummation effects are absorbed into a steep
redefinition of the gluon density, is introduced and its (possible)
interpretation and phenomenological relevance are suggested.
