(448'). It is likely that one also forms where
the stream from the ‘shoulderblade’ flows
under the armpit of the rtorthern arm although
no evidence was observed.
The annual movement of the snout of Virkis-
jökull lias been measured by members of Jökla-
rannsóknafélag Islands. The measurements will
be found in successive editions of ‘Jökull’. The
measurements must be somewhat problematical
since the furthest extension of the ice dis-
appears below moraine and outwash ancl the
snout is about 1000 yards up-valley of this
point. The relative presence or absence of
moraine must be critical in determining the
amount of surface ablation and retreat.
In the summers of 1967/8 Falljökull has
been visited by parties from the Brathay Ex-
ploration Group, an organisation based on
Brathay Hall in the English Lake District
where, since 1947, there has been a permanent
centre which runs four-week courses for boys
in industry. Expeditions are arranged for boys
who have been on the courses and for senior
boys from schools; they are staffed by volun-
tary leaders mainly from schools and universi-
ties. En 1962 the Group was fortunate to be
joined by a nurnber of Icelandic boys who later
visited our lieadquaters with Guttormur Sig-
bjarnarson. Apart from Iceland, parties have
carried out scientific work in many places in-
cluding Norway and Greenland, Poland and
Yugoslavia, Tunisia and in East Africa.
The Exploration Group has visited Iceland
since 1953 and has taken expeditions to the
South-east since 1959 primarily to undertake
studies of the Great Skuas, but in 1967/68 this
