A common feature of the Falkland peat-bogs are low cliffs and terraces caused 
by »peat-slips», local outflows of the peat on sloping ground. 
Where on a slope the peat is partly digged away to obtain fuel, it may 
happen that the rest suddenly starts to move in a violent manner. Thus it is 
reported that once a big mass from the peat-bank above Port Stanley rushed 
through the town, causing severe damage to some buildings. 
In one respect man has affected a striking and miserable change in the appear- 
ance of the islands by letting the pasturing sheep uproot the tussock-grass that 
once formed a vividly verdant brim round the large islands. Now this principal 
adornment of the subantarctic coasts flourishes only on some small islands, 
where the sheep cannot reach it. PI. 6 gives some idea of the contrast between 
such a smilingly green, tussock-clad islet and a coast-scenery from E. Falkland Island, 
a place once certainly covered with tussock but now turned to a vegetationless field 
with barren rocks and small rippled sand-dunes.
