Phenomena such as pulsar frequency glitches are believed to be attributableto differential rotation of a current of ``free'' superfluid neutrons atdensities above the ``drip'' threshold in the ionic crust of a neutron star.Such relative flow is shown to be locally describable by adaption of acanonical two fluid treatment that emphasizes the role of the momentumcovectors constructed by differentiation of action with respect to thecurrents, with allowance for stratification whereby the ionic number currentmay be conserved even when the ionic charge number Z is altered by betaprocesses. It is demonstrated that the gauge freedom to make different choicesof the chemical basis determining which neutrons are counted as ``free'' doesnot affect their ``superfluid'' momentum covector, which must locally have theform of a gradient (though it does affect the ``normal'' momentum covectorcharacterising the protons and those neutrons that are considered to be``confined'' in the nuclei). It is shown how the effect of ``entrainment''(whereby the momentum directions deviate from those of the currents) iscontrolled by the (gauge independent) mobility coefficient K, estimated inrecent microscopical quantum mechanical investigations, which suggest that thecorresponding (gauge dependent) ``effective mass'' m* of the free neutrons canbecome very large in some layers. The relation between this treatment of thecrust layers and related work (using different definitions of ``effectivemass'') intended for the deeper core layers is discussed.Comment: 21 pages Latex.
