We study the quasiparticle spectrum around a single vortex line in a superconductor with {ital d}{sub {ital x}}{sup 2}{minus}{ital y}{sup 2} symmetry. For {ital E}{lt}{Delta}({ital T}), the density of states around a vortex exhibits a fourfold symmetry, in sharp constrast to a superconductor with {ital s}-wave symmetry. This should be readily seen in scanning tunneling microscopy experiments.
