Using the Collider Detector at Fermilab, the W boson differential cross section
(d sigma)/(d Pt), is measured using W --> e nu events in proton-antiproton
collisions at s**(1/2) = 1.8 TeV.  A next-to-leading order theoretical
calculation agrees well withthe data.  The crossection (sigma) for Pt > 50
GeV/(c**2) is measured to be 423+-58(stat.)+-108(sys.) pb.
