We find the metric of a special class of string trajectories, namely, travelling waves on a string, in the weak field approximation. One outcome of this solution is that such string trajectories exert a 1 r force on surrounding particles. We also find the temperature discontinuity across arbitrary cosmic strings. Our result generalizes the result of Kaiser and Stebbins and includes Lorentz and angular factors.
