Fig. 2 gives a general view of Section II, from a 
photograph. The sand with the marks of the pickaxe can 
be seen dividing the upper and lower portions of the gravel. 
Fig. 1 illustrates, on a larger scale, a portion of the top 
bed in Section I. It shows the vertical position of the 
flints and quartzite pebbles, and that some flints have the

corner of Fig. I, and the middle of the right-hand side of 
the same picture), seems to be explainable on the supposi- 
tion that in detachment some ice surrounding the bigger
