Four of the greatest rivers in the island are credited with having more
than half of this power.

WATERFALLS
Dettifoss lies 35—40 km. north-east of the lake Mgvatn and about
125 km. from Akureyri.
This waterfall is formed by one of the mightiest rivers in Iceland,
Jokulsé 4 Fjsllum, where it plunges over a brink into a chasm a-
bout 60 metres in depth, and is said to have the capacity of nearly
half a million H.P.
Gullfoss (river Southern Hvits) is one of the greatest waterfalls in
Iceland; in grandeur it is second only to Dettifoss.
At the top it comes down in a broad fall, some 6 or 7 meires high
and then swirls on, forming lively rapids, till it takes the main plunge
into the deep rift below. This main fall is at least 60 m. wide and 20
m. high, and the volume of water is very great.
Skégafoss is one of the very finest waterfalls in Iceland; its environ-
ments are lovely; steep grassy slopes on either side, the silver dome
of Epjafiallajékull behind it, and in front the blue ocean, from which,
in the extreme south-west, rise the Westman Islands. The river is
rather a small one, but the fall is an even, unbroken sheet of water
over 60 m. high and about 25 m. broad.
This waterfall lies about 160 km. to the east of Reykjavik, most
of which distance can be accomplished by motoring. The scenery is
fine and lwo smaller falls, Selialandsfoss and Glnifrafoss will be
passed on the way.
Godafoss (river Skjélfandafljét) is situated 46 km. to the east of
Akureyri, on the way to Myvatn. It hardly exceeds 12 m. in height,
but its volume of water is great and the environments very charac-
teristic. As to shape, it has often been called a miniature of the
Niagara falls.
Barnafoss lies some 15 km. from Revykjaholi. Here the river
Western Hvitd tears its way through a narrow lava rift, making great
rapids, or almost a fall. But what is of greatest interest here, is the
clear water from some subterranean stream, pouring out from under
