Geol. From hill tops can see hills belonging to Lig. Tertiary plateau running from the point I visited the other day W.N.W. & forming the sky line. Saw an occasional indication of the sombre clays at valley where camped 13 m. W. of astronomical station. Clays of same series pretty well exposed but now very much resembling the Long R. series. Colour not so dark as before & texture somewhat firmer. Show well marked white bands produced probably by alteration of clays by decomposition of Iron pyrites. Much shattered & with many rusty faced cracks traversing in all directions. Hold some selenite, generally in fissures. Little or no ironstone where seen. Small rusty markings running through the stone exactly like those found in Long R. Shale (? fucoids). Other fossils extremely scarce. Think found some fish scales. Found also one baculite [sic] badly preserved, but showing form of two gastropods in outer chamber.

May not this represent the Long R. Series, & the bacculite beds, or sombre clays proper of astron. stn. valley &c. be concealed between Long R..& Wood End?

It seems likely that the clay has had a good many fossils originally, as suspicious traces are very common (as in Long R. Shales). The clay however being non-calcario-us? has allowed absorption of lime while in the plastic state & fully filled up the casts of remains. The baculite found had none of the shell (like those of yesterday) but was meerely [sic] a cast. Owed its preservation to concretion round it of impure ironstone. The two shells caught up with it would tend to show that common if only preserved.

Saw no pyrites, but very likely has been sufficient to, in decomposing, change all the carbonate to sufphate of lime which in the process redistributed.

Many boulders of granite gneiss &c. in the stream beds & on the hills about here.

Saw one of limestone, weathering pinkish white, but grey internally. in the bed of this creek, which has following dimensions: 10'x 6'x 2 '8 " neither the length or thickness fully exposed. Indicates great carrying power of ice.
