very likely recognize not proofs, but indications, along the shores of
South America, that its original people constituted such a stock or
were increased by it.

As respects the possible early connections of America on the side of
Europe, there is an equally extensive array of claims, and they have
been set forth, first and last, with more persistency than effect....

Leaving the old world by the northern passage, Iceland lies at the
threshold of America. It is nearer to Greenland than to Norway, and
Greenland is but one of the large islands into which the arctic
currents divide the North American continent. Thither, to Iceland, if
we identify the localities in Geoffrey of Monmouth, King Arthur sailed
as early as the beginning of the sixth century, and overcame whatever
inhabitants he may have found there. Here, too, an occasional
wandering pirate or adventurous Dane had glimpsed the coast. Thither,
among others, came the Irish, and in the ninth century we find Irish
monks and a small colony of their countrymen in possession. Thither
the Gulf Stream carries the southern driftwood, suggesting sunnier
lands to whatever race had been allured or driven to its shelter. Here
Columbus, when, as he tells us, he visited the island in 1477, found
no ice. So that, if we may place reliance on the appreciable change of
climate by the precession of the equinoxes, a thousand years ago and
more, when the Norwegians crossed from Scandinavia and found these
Christian Irish there, the island was not the forbidding spot that it
seems with the lapse of centuries to be becoming.

It was in A.D. 875 that Ingolf, a jarl of Norway, came to Iceland with
Norse settlers. They built their habitation at first where a pleasant
headland seemed attractive, the present Ingolfshofdi, and later
