We report the results of more than a year's timing observations of the binary pulsar PSR 1913+16. Within the accuracy of our measurements, about +- 300 ..mu..s, the pulse arrival times are exactly those expected from a clock of well-defined period, moving in a Keplerian orbit with a constant rate of apsidal advance. The observations have yielded much-improved values for the parameters of the pulsar and its orbit, and are approaching the length of baseline needed to perform certain tests of the gravitation theories. We place an upper limit 60..mu..Jy on peridically pulsed radio emission from the companion object. (AIP)
