The elastic photoproduction cross sections for rho and phi mesons from protons have been measured from 30 to 180 GeV. The energy dependences agree well with predictions made by using vector-meson dominance and an additive quark model. The rho cross section is approximately constant with energy while the phi cross section rises from 0.5 to 0.7 ..mu..b with increasing energy.
