Coarse and fine were arranged along the same horizons. The layers. 
or lamine ofice which were close together where only silt and 
sand were present separated so far as needful to admit bowlders. 
It was interesting to observe that the lamine as they approached 
a bowlder parted, a portion curving over the bowlder and a por- 
tion curving under it. No good photographic illustrations of this _ 
were secured from this glacier, but fair ones from other glaciers. 
will be given later. Many of these other glaciers show the 
phenomena of stratification and the inclusion of débris so much 
more clearly and pronouncedly that we may leave further details 
to be subsequently described. 
The débris was enclosed almost exclusively in the basal beds, 
the upper portion of the glacier being almost entirely free from 
rocky material.. The distribution throughout the lower layers 
was not strictly progressive from the base upwards. Higher 
layers sometimes contained more than lower ones, but the general 
fact of basal distribution was very pronounced. It was furthet 
observed that there was more débris in the layers near the sides. 
of the glaciers than in the central portion. This is expressive of 
a law which somewhat widely obtains. 
The top of the glacier was not reached by us, but from what 
could be seen it appeared to be essentially free from bowldery 
erratics, though somewhat discolored by atmospheric dust. 
The débris which was embedded in the Fan glacier was. 
largely composed of a hard pinkish sandstone derived from the 
middle member of the clastic series previously described. There 
was present, however, a considerable sprinkling of crystalline 
bowlders of the granitic type and occasionally bowlders of the 
greenstone type. If it is recalled that the source of this ice-flow 
was probably not more distant than the middle of the peninsula, 
the stratigraphy beneath the glacier is readily inferred. The 
uppermost member of the clastic series which occurs in the sides 
of the valley adjacent to the lower part of the glacier must soon 
be replaced at the surface by the rising of the pink sandstone
