The history of Greenland really begins about the year 986 A. D., when Eric the Red, a chieftain who had been banished from Iceland, landed on the island with some of his followers and made it his permanent residence. At different times these hardy and daring seamen made expeditions to the eastern coast of North America, and sailed as far south as Chesapeake Bay. They attempted to found a colony on the east coast at a point thought to be on the coast of New Jersey but, after contending with the savages for some time, deemed it best to abandon the project and to return to their Greenland home. The location at which they attempted their colony is by no means certain.

All this island, a half million square miles in area, except a small part of the southern coast line and a larger area in the north, is covered by an immense glacier. And this field of ice, like a huge piece of plastic wax, is constantly moving from the interior down toward the sea. As it approaches the ocean it divides into branches which flow down the numerous fiords and valleys into the sea. As the fronts of the branch glaciers are pushed out into the water their ends are broken off by the buoyancy of the water. These glacial-born masses then float away as icebergs, carrying with them on their southward journeys the rock waste—moraine detritus it is called—gathered by the parent glaciers.

When these floating leviathans are off the coast of Newfoundland, they encounter the waters of the Gulf Stream, melt, and scatter their dÉbris of stony matter over a large area of the ocean bed. This process, having gone on for thousands of years, has shoaled the ocean in certain parts, forming the so-called Banks of Newfoundland.

A gelatinous slime filled with minute animal life forms on the bottom of the ocean in the arctic; the cold currents flowing south carry some of it along with them, and much of it is lodged on the stony bottoms of these banks. Fish, especially the cod, are fond of this gelatinous substance, and throng thither at certain seasons of the year in countless numbers to feed upon it.

One ignorant of the currents of the ocean might be puzzled at times in observing that an iceberg floats southward at the same time that pieces of wood are floating northward, both apparently acted upon by the same current. This may be explained by recalling that warm water is lighter than cold and hence is found as the upper layer when a cold and a warm current are flowing in different directions, one upon the other. It should be borne in mind that seven-eighths of the floating iceberg is under water, leaving but one-eighth above the surface. The Gulf Stream drift spreads out as it travels northward, and, being much shallower than the arctic currents, carries floating objects northward on the surface, while the deeper and more powerful arctic currents force the huge masses of ice southward.

When the warm air over the Gulf Stream comes in contact with the floating ice it is chilled, and the moisture which it holds is condensed into fog. The fogs in turn, which are off the Newfoundland coast, being in the line of steamship communication between Europe and America, are a constant menace to navigation. The near presence of ice is usually detected by a greater chilliness in the air. In order to avoid collisions with one another, and also with icebergs, a ship constantly sounds its sirens and fog horns as warnings while in the fog belt. The signal of another steamship is a warning of the one; the answering echo announces the nearness of the other.

The high interior of Greenland, about ten thousand feet in altitude, is thought to result largely from the accumulation of ages of snow and ice, only a part of which melts or moves oceanward to form glaciers. No other part of the world is such an absolute desert as the greater part of this island. Animal and vegetable life are wholly absent.

The colony which was planted in Greenland by Eric the Red, and subsequently augmented by other Norsemen, continued to prosper for four hundred years. At the end of that period there were about two hundred villages, twelve parishes, and two monasteries. These, however, disappeared. The hostility of the Eskimos in part accounts for their extinction, but an encroachment of ice from the north, which encompassed the southern part of the island, is thought to have been also a factor. The fact that foreign trade with Greenland was forbidden by the mother country may account in part for the gradual disappearance of the colony. At all events, intercourse with Europe seems to have been cut off. This condition continued for upward of two centuries, and when intercourse with the mother country was again possible there was no Greenland colony. Perhaps the finding of "white" Eskimo in Victoria Land may explain this disappearance.

Subsequently the island was again colonized, but concerning the disappearance of the former inhabitants history is silent. The mute testimony of a few ruined buildings and relics is all that has been found to give the least shadow of information as to the final struggle of the wretched colonists. We only know that they mysteriously disappeared. But the great glacial cap is slowly receding and ages hence more ground will be laid bare.

The present inhabitants number about ten thousand, most of whom are Eskimos. They are lacking in thrift and live chiefly by hunting and fishing. Among the wild animals living here are the arctic fox, the arctic hare, the musk ox, the seal, the polar bear, the ermine, and the walrus.

The principal resources of the island are sealskins, eider-down, oil, and cryolite.

Cryolite is a mineral from which common soda is easily extracted, and also from which the light silver-like aluminum was formerly prepared. The mines near the village of Ivigtut furnish practically the world's supply of this mineral. Formerly it was carried to Philadelphia, but in recent years not much is used. The fisheries are a monopoly of Denmark, and each station is visited from one to three or four times a year.
