A simple, largely mechanical device for automatically collecting periodic discrete water samples for use in dye tracer studies has been developed and successfully used by the U.S. Geological Survey. The device consists essentially of two rows of spring‐loaded hypodermic syringes that are released from their closed position at selected time intervals to draw in and retain the desired water samples. The sampler is mounted in a boatlike structure partially immersed in the flow to be sampled.
