of limestone as already mentioned. The whole dipping gently Nwestward. Ascending the W. side of watershed the rocks seen mostly greenish slates but not well exposed. The upper red beds cap the hills on the left hand & of the watershed ridge & appear to dip westward into the base of the ridge. The red beds are underlain by fawn-coloured beds which are probably chiefly of limestone or calcareous grit. These followed by the amygdaloidal trap bed, not nearly so thick however as when seen in Mt Yarrel. Then the great limestone series weathering columnar & craggy when on the peaks but flaggy & shelving when cropping out in hillsides.

Beds immediately below limestone not well seen, but probably all variagated sandstones &c. The crimson beds, or lower red Series then come in say about 200'.

(These red beds were not distinctly observed in Mt Yarrel section).

Below the red beds & forming the point of the hill near camp No. 1. which seperates the S.Western & Western branches of the pass. Variagated sandstones & quartzites.

A gentle anticlinal runs nearly W. (Mag.) into the nose of the mountain mentioned, & follows the ridge seperating the two brooks. In the S.W. Brook a lower greenstone trap is exposed. Very hard but so traversed by joints & slikensided surfaces that hardly possible to obtain a clean faced specimen.
