had disappeared, but otherwise the vegetation of the burnt patch 
showed little change. On some parts of the burnt area nearly every 
plant of Ulex minor was sprouting from the base, the new growth 
being very closely adpressed to the surface of the ground as a general 
rule (cf. p. 152 and PI. V, fig. 4); at other points the C/tev-plants 
over an area of two or three square yards showed no sign of resuming 
growth. Numerous t7/eA:-seedIings were present, but their number 
in comparison with January seemed to have diminished, and from 
other observations it appears very probable that only very few of 
them prosper. At some points on the burnt patch Molinia was 
reappearing, this growth again arising from the old plants (Text- 
fig. 3). Here and there very isolated fronds of Pteridium were

coming up, hut no other forms yet showed any indication of 
growth. By July of this year a vigorous growth of the sprouting 
gorse had taken place, sufficient to give a greenish tinge to the 
whole area when viewed from a little distance. The seedlings of 
Ulex minor were however doing rather badly and gave no great 
promise of future success. This is in marked contrast to the 
behaviour of the seedlings of U. europceus on the part of the burnt 
area situated in the valley A ; many of these looked very robust and 
had attained a height of 6-8 ins. above the level of the ground, their 
growth being no doubt favoured owing to the protection afforded to 
them by the dense mass of tall bracken that occupies the valley 
(cf. above). A considerable number of Vaccininm -shoots were now
