“On approaching the coast of Iceland we got occasional soundings
towards Ostré Horn, under which we were obliged to anchor in a dense
fog, after getting inside an extensive and dangerous reef of rocks,
called by the Icelanders the Hartinger and Bortinger. These reefs lie
two miles east (true) off this cape. They do not appear on the Danish
surveys, but I afterwards found them as a single rock upon a French
chart.”
