  The observed absence of gravitational aberration requires that ``Newtonian''
gravity propagate at a speed $c_g>2\times10^{10}c$. By evaluating the
gravitational effect of an accelerating mass, I show that aberration in general
relativity is almost exactly canceled by velocity-dependent interactions,
permitting $c_g=c$. This cancellation is dictated by conservation laws and the
quadrupole nature of gravitational radiation.
