more so than their texture, and a bank which from a distance 

 frequently shows a perfectly banded appearance from top to 

 bottom in shades of drab, yellowish, light brown and purple-grey, 

 when approached more closely, loses all distinctness, and it is 

 almost impossible to draw well defined lines between the layers 

 in a measured section. The formation, though showing some 

 slight undulations on a small scale, does not appear to have any 

 definite direction of dip, and it is therefore difficult to correlate 

 the beds seen in different places. 



Many seams of lignite coal crop out in this part of the Souris 

 Yalley, the thickest observed was 7 feet 3 inches, and from this 

 they show all iotermediate degrees of thickness down to layers 

 <of a few inches only. 



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

 may be taken as an illustration of the manner of alternation of 

 the deposits. The beds are arranged in descending order:
