et.Every film of sediment proclaims that the fashion ofthe planet has been worked over to some extent.The making of the planet has been merely a progres-sive changing of the fashion of the materials ofwhich it is composed. If the completed planet as wesee it is the product of geological forces, then thework of sedimentation proceeds by means of forceswhich are geological. The filling of boyhood^s mill-pond was a geological work. The slime settled bythe roadside is a geological phenomenon. These areresults accomplished. The sediments have been brought by moving Thesedi- waters; we must therefore trace the waters to their journey sources ; we must retrace their course from the higher traced,level. Obviously, the roadside slime has descendedthe rill-ways from the middle of the street; from thehill-slope down which a portion of the water de-scended. Some water flowed down the field-slope,moved under the fences, and found its course to theroadside pool, bringing as much sediment with it as

The corn-fields have beentaxed; the earth built into the highway has beenstolen; the form and bulk of the hill have beenchanged. So the farmers fields contributed thematerial which lies in the bottom of the mill-pond.To some extent, the fields have been scraped downand impoverished. There lies the farmers propertyspread over a surface which forms the floor of thesunfishes home. Over every square mile flows some stream. Thesmallest stream, as well as the largest, occupies avalley; and down its slopes descend the sediment-laden drainage waters which seek the stream to join vin its journey to the lower levels. Follow the stream-let. Along every rod of its course we find dischargedduring a rain the muddy washings of the land. Thestreamlet grows. Many a lateral rill brings in itscontribution from the fields which stretch in anotherdirection. Our streamlet flows on, and sooner o
