Bd. III; 2) CONTRIBUTIONS TO THE GEOLOGY OF THE FALKLAND ISLANDS. 31 
On the south coast we meet Port Albemarle (Fig. 15, depth increasing gradu- 
ally from 13 fathoms in the inner part of NW. arm to 25 fath. in the outer part 
of the bay) and Port Stephens (27 fath.); on the west coast we find the largest 
bays in the island group: Queen Charlotte Bay, King George Bay and Byron Sound 
(the two first mentioned with depths descending to more than 40 fath.). These 
wide waters seem to me to be comparable with the southern deep part of Falkland 
Sound, and like this their origin may be due partly to subsidence along fault- 
lines. These waters are left out of consideration in the following discussion.^

(Copy from the Admiralty Chart [1114]). 
Bays of the common type on the west coast of W. Falkland are South Har- 
bour (20 fath.), Port Richard (25 fath.). Port Philomel (depth of the inner flat 10 — 
13, in one spot 19!, in the narrow entrance 14 — 16 fath.). At the mouth of Port 
Richard open some typical creeks: Double Creek (12 — 15 — 18 fath.), Carew Harbour 
(15 — 19—20 fath.) etc. One of the most riverlike creeks in the whole island group 
is Chaffers Gullet (16 fath.) NE. of Port Albemarle (see Fig. 15). 
As a rule the depths of the Falkland bays increase from the innermost shal- 
low branches towards the mouth. In some few cases the Admiralty chart records 
' It ought to be remarked in this connection that possibly also the exterior part of Berkeley Sound 
may be supposed to be limited by fault-lines.
