than the present climate of the Falkland Islands. I think that the then state of 
these islands must have been very much like the Bear Island of to-day: large de- 
position of snow in wintertime, rapid snow-melting during the summer and a scarce 
and imperfect plant-cover, that offered very little resistance to the soil-flow.

After these introductory remarks I will relate my detailed observations concern- 
ing the stone-rivers. 
As to the extent and distribution of the stone-runs in the island group I have 
only some scattered notes. N. of Port Stanley I saw the phenomenon well de- 
veloped on the south slope of Mount Low as well as W. of the town near Mount 
William. S. of Port Louis (Berkeley Sound) is the giant stone-river described 
by Darwin, and moreover here almost every mountain-slope is covered to a large 
extent by a net-work of »streams of stones». 
I noticed a very splendid development of the stone-rivers in a voyage along 
the south coast of East P'alkland. Behind the lowland forming the south part 
of the island, I saw in the distance the Wickham Heights, the principal water- 
shed, in its full extent. Every transverse valley of the low mountain-range is filled 
by the grey mass of a stone-river extending to or upon the lowland at the moun- 
tain’s foot. The resemblance to a region crowded by valley glaciers was really 
amazing.
