coloured gypsum. One nodule seen about 6 ft long. Presented appearance below

The brook in which section occurs is one of those running streams which flow E. over Pembina Mt & disappear below the level of the plain.

Barom. at 9 P.M. 28-68 (for height of camp & beds above described).

May 23. Left camp at 7.45 with Capt. F. H., King (6) & sappers. All mounted & with a pack horse to carry tools &c. Capt. F. going to put in pickets on the line agreeing with the [Fort] Garry Meridian used in all Manitoba surveys. Went into Pembina Mt. by the trail used last June for running the line. Got to Pembina R. valley about 2 P.M. Examined sections &c. Collected plants & got back by the same trail with Nilson about 8 P.M. after a very fatiguing day. The remainder of party staid behind till last moment to run the line & have not yet (9.30) turned up. The trail is a very rudimentary one, & to learn the full value of Red R carts one has to see it. In many places it seems dangerous for horses. Much of the riding through bushes taller than the horse, & exceedingly steep hills & pitches. Several deep coulées & gullies are crossed, showing sections more or less complete.

The greater part of the region between the brow of Pembina Mt & Pembina R. (over 7 miles from camp to Pembina R. on line) is wooded with small groves of poplar now vividly green. Much burnt wood however disfigures the appearance. Many open glades, often swampy & sometimes with ponds. General run of these & of longest axes of poplar groves nearly N. & S.

The terrace levels spoken of last autumn are very distinct here. Got Barometric levelings for them, though day rather bad, being overcast, changeable & showery. The first terrace is about 1/3 above the level of the plain. The second forms the apparent brow of the Mt, & is 3/3 above level of plain (say). A still higher though less definite level is found on ascending the mountain.

The exposures in gullies & on the bank of Pembina R itself all show typical Long R. Shale, differing somewhat from that seen yesterday & resembling that found overlying the fish-bearing shale at the Crossing of the regular trail with Pembina R.

No fossils found or any appearance of organic remains except
