LOESS WITH HORIZONTAL SHEARING PLANES 251 
results. Over a snow-covered region of this kind there would 
be ideal conditions for loess-making. A slow creeping of the 
entire field might very well be supposed to take place in the 
direction of the general slope of the land. 
It is not my desire to discuss these possibilities here. The 
object of this communication is merely to call attention to this 
new feature of the loess, and, if possible, thereby to secure more 
observations on its occurrence.
