[16-2] An island midway between Iceland and Greenland, discovered in the
latter part of the ninth century. Gunnbiorn was a Norwegian. This island
is no longer above the surface. See Fiske, _The Discovery of America_, p.
242.

[17-1] This should read _Eastern_ Settlement, evidently a clerical error
in an original manuscript, as both Hauk's Book and AM. 557 reproduce it.
There were two settlements in Greenland, the Eastern and Western, both,
however, to the westward of Cape Farewell, and between that cape on the
south and Disco Island on the north. Ericsey (_i.e._, Eric's Island) was
at the mouth of Ericsfirth, near the present Julianshaab. For further
details on the geography of these settlements, see Reeves, _The Finding
of Wineland the Good_, p. 166, (25), and Fiske, _The Discovery of
America_, I. 158, note.

[17-2] On the western coast of Greenland, about 70° N. Lat.

[17-3] The saga up to this point is taken from Landnama-bok, the great
Icelandic authority on early genealogy and history. It might well have
included one more paragraph (the succeeding one), which gives an
approximate date to the colonization of Greenland: "Ari, Thorgil's son,
says that that summer twenty-five ships sailed to Greenland out of
Borgfirth and Broadfirth; but fourteen only reached their destination;
some were driven back, and some were lost. This was sixteen [S: fifteen]
winters before Christianity was legally adopted in Iceland." That is, in
about 985, as Christianity was accepted in 1000 (or 1001). There is a
possible variation of a year in the usually accepted date. See _Origines
Islandicae_, I. 369.
