190 several little raised beaches showing where the level had been, formed of washed gravel and stones—the counterpart, in fact, of the raised beaches of the geologists. When the water was almost all drawn off, then there was a deep winding channel in the mud of the bottom, along which trickled a little streamlet which fed the pond. The sun hardening the mud, it was possible by-and-by to walk to the edge of the channel, where it could be seen that the streamlet ran five or six feet deep between precipitous banks of mud.

Near where the stream first entered the pond the deposit was much deeper, for this five feet of alluvium had, in fact, been brought down by one small brook in the course of little more than fifty years. The pond had been formed fifty years previously, but already in so short a period, geologically speaking, all that end was silting up, and the little brook was making a delta, and a new land was rising from the depths of the wave. This is exactly what has happened on an immensely larger scale in the history of the earth, and any one who had seen it, and knew the circumstances, could comprehend the enormous effects produced in geological time by rivers like the Ganges, the Amazon, or Nile. Going by with a gun so frequently, one could not help noticing these things, and remembering them when reading Lyell's "Geology," or Maury's book on the sea, or the innumerable treatises bearing on the same interesting questions. Whether en route for the rabbit-ground, or looking for water-fowl, or later for snipe, I never passed by without finding something, often a fragment of fossil washed from the gravel or sand by the last storm.
