 several places, most distinctly in Turner Sund, at the loose 

 layers on some of the slopes I noticed a fine striate arrangement 

 on a small scale: coarse and fine gravel or even clay alternated 

 in long, regular, narrow strips, sometimes covering extensive 

 tracts. The steeper the slope was, the more regular were the 

 strips, and while in general the clayey strips, at least, were

moist, the phenomenon was also observed on dry ground. A 

 somewhat indistinct picture of the appearance of this "striate 

 land" is given in fig. 33. There was no further chance during 

 the Greenland Expedition of taking other observations touching 

 its origin, but I have since continued these observations in 

 other places. Here 1 need only mention that 1 fully subscribe to 

 Andersson's explanation of solifluction, but for the origin of 

 the narrow regular strips described I consider it necessary for
