ground for fossils above the great fossil bed, Ogygopsis shale, is in the Mount Bosworth section on the continental divide.

The principal locality from which good fossils can readily be obtained is on the slope of Mount Stephen, above Field. The best way to make a collection from the "fossil bed" is to ride up the trail on a pony to about 2000 feet above the railroad, collect specimens, securely wrap them in paper, place them in a bag, tie the bag to the saddle, and lead the pony down the mountain. A fine lot can be secured in a long day's trip, 6 a.m. to 6 p.m.

In order that the reader may understand the location of the "fossil bed" and the position of the various formations in the Mount Stephen section, four photographs taken in 1907 and a geological section are given in connection with this paper; also a list of the fossils from the "fossil bed" and illustrations of the more common species.

No. 1. Northwest fact of Mount Stephen, showing the Kicking Horse River at the base.

A—The railroad tunnel.
B—The great north shoulder.
C—The lower bluish-black limestone belt.
D—The upper bluish limestone belt.
E—The celebrated "fossil bed."
F—Best locality to camp in working "fossil bed."
G—East slope of Mount Dennis.

No. 2. View looking northwest from the "fossil bed," which is shown in the foreground. The trail from Field can be followed with a saddle animal to the large dead pine tree on the left. Just below this is the ridge upon which the trail is located. To the left of the ridge
