The tendency of the tertiary streams, or streams of the third order, to swing into parallelism with the strike, is illustrated by the tribu Fig. 33. The junction of the tributaries of Raccoon creek with their main. taries to Raccoon creek, shown in Fig. 33. The main stream is here at tide-level, and long since ceased to lower its valley. The lower ends of the tributaries turn so as to flow along the strike, and join their main at a right angle. In the figure, the dotted lines indicate the probable course of the streams before adjustment. The phenomena of Raccoon creek are repeated in Mantua creek, where Edwards run joins it, and in the lower course of the Chestnut branch, where it enters Mantua creek, just below Wenona. Similar phenomena, though to a less extent, are seen along Timber and Cooper's creeks. Fig. 34 shows the same tendency manifested in a slightly different way along Pensauken creek. The south branch of this creek originally had an independent course to the Delaware through the Pachack, but a tributary of the north branch, heading back from d, Fig. 34, on one of the softer layers of the Cretaceous, made such headway that it captured the south branch and diverted it to the north. The present Pachack is therefore a beheaded stream, and the low pass along the dotted line, representing the abandoned course of the south branch, is merely a wind gap, inconspicuous because the region is so Fig. 34.
