The shower was arranged so thatthe bulk of the water fell at the center of the model, but some parti-cles of water were carried beyond, while others fell short, the resultbeing that there was a zone of maximum rainfall extending from one sideof the model to the other and passing over the dome. This necessarihinfluenced the drainage. As shown in PL XLVI, A and B represent-ing an earlier and a later stage of degradation, two main streams devel-oped in the line of maximum rainfall, flowing in opposite directionsfrom the dome, and in a Very short time after erosion commencedthey had captured all the drainage, which, as shown in PI. XLVI, -4,was initially radial. Seveial small streams consequent upon the initialslope flowed from the dome and united near its base to form the fourencircling master stre
