It is suggested that a single source of cosmic rays (supernovas) occurring in all galaxies can produce the observed spectrum and the observed anisotropy, and is predictable from supernova shock theory. Below 10 to 100 trillion eV the source and observed spectrum are the same, with N (greater than E) proportional to E to the minus alpha power, alpha approximately equal to 1.75. Above 100 trillion eV I predict a source with alpha approximately equal to 1.2. Galactic leakage above 10 to the fifteenth power eV is linear so that alpha approximately equals 2.2 as observed. Above 10 to the nineteenth power eV, cosmic rays fill the metagalaxy to a flux several times the anisotropic residual flux from a few events in our galaxy as observed.
