Sept 15. Started 5.45 & travelled 10 miles. Stopped till noon. Feed being good. Travelled on again 11 miles & made camp at creek with pools of rather alkaline water, surrounded by white effervescence. The Country on the Tertiary plateau comparatively fertile & with a thick & close growth of grass, still quite green wherever moisture. No cactus on this plateau, or on that W. of White R. Showing better character of soil & less droughty conditions.

Geol. The Eastern edge of the Tertiary plateau is descended by the road about 30 or 31 miles from White R.

At Camp 34 m. W. of Woody Mt find exposures of sombre clays as suspected (see July 9). These must belong to a bay of Cretaceous extending into Tertiary from the N.
