 frcf|uently shows a porfoetly bundod appuaranco lioni top to 

 bottom in sliados of drab, yellowi.sh. lii;lit brown and purple <;roy, 

 when aj.prcdchod more closely, loses all distinctness, and it is 

 almost injpossiblo to draw well defined liniis between the hiyers 

 in a measured section. The forni.ition, thon^-h showing some 

 slif;ht undulati(ms on a small scale, does not aj)pe;ir to have any 

 definite direction of dip, and it is jfore diflicult to correlate 



the beds seen in different places. 



Miiny seiinis of li-nite coal crop out in this part of the Souris 

 Valley, the tliickest observed was 7 feet 8 inches, and from this 

 they show all intermediate degrees of thickness down to layers 

 of a few inches oidy. 



The following is one of many sections seen in tliis locality, and 

 may be taken as an illustration of the manner of alteri.:ition of 

 ■ the deposits. The beds are arranged in descending order:
