between them. (In the red "brick" found some remains of plants but not at all perfect. In large flat topped hills to N would expect to find the lignite intact which has caused combustion &c. over the area now in question.

"Clinker" is found in some places among the red rocks evidencing the mode of formation.

The uplands show an example of a country shaped by rain. The clays being incapable of supporting much herbage, wash away into conical or rounded hills which are scored from top to bottom by runnels of water. In dry weather the surface cracked or crumbling. If any capping of sandstone or hardened clays (as by combustion) conical hills formed (like Pyramid Creek, Great Cañon &c.) If not rounded "mud lumps" are produced.

The streams in the vallies at lower level have wide beds but are very tortuous & are still widening them & cutting into their banks. Small ravines run from the main vallies up into the uplands. Country has all the aspect so far as I can judge of the "bad lands" proper & owes its character to combination of similar circumstances.
