with which and two smaller craft he again sailed in May, 1577. Passing Friesland, he steered for Labrador, and touched at the strait which still | bears his name. He passed up this inlet in a boat, supposing the land on his left to be America, and that on his right Asia. The strait being cleared of ice by a N. W. blow, he sailed westward for 30 leagues, confidently supposing that it led to the Pacific. Ice beginning to form around the ships, it was considered hopeless, for the season, to proceed further on the (imaginary) voyage to China; and therefore the squadron took on board about 200 tons of the glittering dross previously discovered, and returned to England.

Strange to say, the golden delusion was not yet dispelled. Scientific men, appointed by the queen, pronounced the ore genuine, and the passage to India feasible. Honors and rewards were lavished upon the fortunate adventurer without stint, and fifteen vessels were soon placed at his disposal, with which he sailed once more.

The fleet encountered great dangers from tempests and icebergs, and at last entered a great strait to the westward, probably the chief entrance to Hudson's Bay; but the fears of his associates compelled the return of the squadron without accomplishing any thing worthy of its magnitude. The worthlessness of the trash he had formerly brought home was by this time discovered, and he could obtain no further aid to second his enterprises. After a life passed in naval adventure and warfare, he perished in 1594 from a wound received on the coast of France.

JOHN DAVIS.

On the 7th of June, 1585, this excellent and kind-hearted seaman sailed from England with two

effect further discoveries. He coasted along the western shores of Greenland to lat. 64°, where he landed, and was soon on friendly terms with the natives whom he astonished not a little by music from a band which he had taken with him. Thence he steered across the great strait which still bears his name, and after touching at Cumberland Island, and making some further explorations, returned home in autumn.

He sailed again on the 7th of May following; and after renewing his intercourse with the Esquimaux in Greenland, who ere long began to " practise their devilish nature," he crossed Baffin's Bay. On the 17th July he saw what was supposed to be an extensive coast, diversified with hills, capes, and bays; but, to his horror, found it only a "most mighty and strange quantity of ice." His crew remonstrated against proceeding farther, but he pushed on with his boldest mariners in the Moonshine, until he reached lat. 66° 33′, whence he coasted southward by Labrador, and so made his way to England. The English cod-fishery, since so valuable, may trace its slender beginning to this voyage-Davis having fallen in while returning with immense shoals of these fish.

In a third expedition, undertaken in 1587, Davis left his vessels at their former station on the coast of Greenland, and in a pinnace, “so dull that she sayled like a cart drawn by oxen," penetrated northward beyond 720, and made fresh surveys of the two coasts. On returning to his rendezvous, he found that his vessels had deserted him, and, not having much choice left, he safely conducted his slender and ill-sailing little craft to England, where his unexpected arrival created no little excitement; but he was never encouraged to undertake another voyage.

ANCIENT NOTIONS OF EUROPE.

Ir is not here proposed to enter into any extended detail in regard to the countries or people of antiquity; and this is rendered the more unnecessary, as the various phases which nearly all of them have assumed at different periods, will be noticed incidentally in other portions of our work. In this division, we shall only cursorily glance at the limited ideas which prevailed in early times, and touch briefly upon what was known as the Europe of antiquity and its two most prominent people.

It has been truly said that "early ancient geography lay in a very narrow compass." Greece and Italy were the extent north and west, and the Indies on the east. The Persian Gulf, the Caspian, the Euxine, and the Mediterranean bounded the countries consecrated in Ancient History, and which extended over 20 degrees of longitude, or about 900 miles, by 12 degrees of latitude, or over 1800 miles. Arabia and Egypt lay to the south-west, and Chaldea bordered on Arabia, south of the Euphrates; Babylonia lay between it, on the Tigris; Assyria was in both; Media to the west, and Parthia to the north; Syria lay to the west, and its extent was but 400 miles long, and about 100 wide. The priests taught that the Temple of Apollo at Delphos was the centre of the world; beyond the Archipelago and the Levant, was all fable; and they believed that the whole plain of the earth might be viewed from any very high mountain! A volume of no circumscribed dimensions might be filled by a mere enumeration of the vague and absurd teachings of this reputedly infallible class; but as we have

"metal more attractive" for our readers, we shall spare them any further details of the ignorance and stupidity which generally prevailed, and confine ourselves to facts of more positive value.

ANCIENT EUROPE.

EUROPE (Expón) occurs for the first time in the Homeric Hymn to Apollo, where it does not indicate the continent, but simply the main-land of Hellas proper, in opposition to Peloponnesus and the neighboring islands. Herodotus is the first writer who uses it in the sense of one of the divisions of the world, and he considers it to be derived from Europa, the daughter of Agenor, king of Tyre, although he does not seem perfectly satisfied of the fact. Another learned author asserts with some confidence that the "continent of Europe derives its name from the worship of Eur-op, the Serpent of the Sun;" while Professor Anthon, in our day, regards the name as of Phoenician origin, denoting the " Evening Land" that is, the land of sunset or gloom, in opposition to Asia, the " Land of Light.”

In earlier times the River Phasis was usually supposed to be its boundary, and sometimes even the Araxes and the Caspian Sea; but at a later period the River Tanaïs and the Palus Mæotis were usually regarded as the boundaries between Asia and Europe. The north of Europe was little known to the ancients, but it was generally believed, at least in later times, that it was bounded on the north by the Frozen Ocean. Ptolemy's boundaries are in brief: N. by the Northern Ocean, W. by the Atlantic, S. by the Mediter
