the base, so far as seen here, below this camp; & the dip Eastward, If any, the thickness seen must be at least 200 ft.

It seems probable that the series may overlie the Long R. Shales seen E., or may form their upper part (or represent them). The nature of the sediment not much different, but the clays less consolidated. The ironstone often Septarian. Clays may represent Hector'sl Septarian clays division C. but in this case according to him would underlie Long R. Shales. (See Palliser P.226). These clays seen by him at Elbow S.Saskatchewan &c, &c. (See Palliser PP. 226 & 54.)

Probably the same division as No. 4 (as given in Palliser) of Hayden's Missouri section. Said to be principal fossil bed of region & might very well in favourable locations from perfect preservation of remains. Selenite crystals diffused through the sombre clays.

Seem to have in Sect of June 29 junction of Cret. & Tert. well shown.

Division C. section may represent Haydens Gr. 5 & would not differ much from it in thickness.

Travelled W. over a very rough road & arrived at Ashe's deserted camp on a creek 13 m. W. of astron. stn. about 1 PM. Camped.

Crossed two other creeks on the march but none have any flowing water now.

The hills are barren & very dry, the vallies stony or clay bottomed & barren. Some fair grass however along the streams.
