Summary, Etc.(with French, Russian and Spanish) A gauge-to-page system for automatic computation of streamflow records has been developed by the U. S. Geological Survey as a result of continuing studies since 1952. The basic components of the system, which is now in operation at 2,000 gauging stations are a digital stage recorder, a paper-tape translator and a general purpose digital computer. The digital-stage recorder is a battery-operated slow-speed paper-tape punch which records a four-digit number on a 16-channel paper-tape at pre-selected time intervals. The recorder is basically a device for coding and recording the position of an input shaft, but it can be adapted to accept a voltage input, to record several variables in sequence, or to transmit data by wire or radio. The paper-tape format is a unique configuration which requires rearrangement before input to any present high-speed digital computer. Because input requirements for different computers vary considerably, this seemingly redundant translation step actually precludes obsolescence of the field recorder. The translation permits adaptation of the basic record to the input from required by any present or future computer
