ford saw that they had crossed the river & were several miles away. Long after all the rest had passed an old bull who had been left behind in some way appeared following the herd as fast as he could to catch up. The buffalo paths are very useful as guides up & down such valleys as that of the Milk R. They are found guiding to every practicable route & are generally followed by horses without difficulty. They also follow the courses of the vallies choosing the best fords & making as straight lines as the nature of the ground permits.

Saw a curious indian grave in the bottom of the valley. A nearly cylindrical concretion from the sandstone had been buried obliquely in the ground & painted with Vermillion. Other stones surrounded this & many offerings or gifts had been left & apparently recently renewed. Beads, a spoon, tobacco, buttons & strips of various coloured Calico prints. Also a flat ornament composed of porcupine quills woven together & a number of eagle feathers.

Geol. The beds exposed in the banks of Milk R. are undisturbed & regular. The section is divided into an upper & lower part by a zone of sandstones which are about 1/3 from the top of the bank near the line, but which on following the R. Westward for about 8 m. from the very summit of the bank, showing a gentle dip of the formation Eastward. The sandstones though often well & evenly bedded are not regularly hardened but exhibit a nodular character & in some places false beddes [sic] as well. Thus the sandstone strata may be almost quite hardened at one place & a mile or two away may show only certain hard layers separated by unconsolidated sands.

Below the sandstone occur clays, sands, & sandy clays well stratified & individual beds of which may be traced a long way up & down the valley. The colours are generally light but there are some zones of carbonaceous clays & in one or two places impure lignite of no great thickness was observed. It appeared to be more discontinuous than the other beds & to thin out soon & disappear in both directions.

Above the sandstones a considerable thickness of sands & sandy clays much thicker in their bedding & the stratification of which is less plainly marked. The general colour of these upper beds is pale yellowish buff, but in some places chiefly greyish.

No fossils were found in the upper series, or in the sandstones.
