It will be noticed that both Vesuvius and Ætna seem to have reached their maximum activity at the close of the last century. The same is true of the volcanoes of Iceland. This island, which is as large as Ireland, is built up entirely of volcanic matter. It doubtless began with a single, great submarine volcano; but to-day it has at least thirteen active vents. It presents us with the most tremendous outpour of matter in the history of the world. For seven hundred years there has not been an interval of forty, and seldom of more than twenty, without eruptions and earthquakes in some portion of the island. Single eruptions of Mt. Hecla have lasted six years. Often during violent earthquakes, old mountains have disappeared; new ones have been raised up; rivers turned from their courses, or dried up altogether. The old Norseman who discovered the island might much more appropriately have named it Fireland. Doubtless had his ancestors known the island they would have chosen it as the home of the terrible fire giants. But Iceland is the realm of both frost and fire; and there is no more romantic or painful chapter in history than the story of this hardy and spirited race to maintain their foothold in the face of such terrible odds. Those who hold that a nation’s progress and stamina are in proportion to its material advantages, would have to make an exception in favor of blood. The plucky Norsemen have held their own in this region for nine centuries; nor is there any deterioration. No nation can to-day show a better intellectual or moral condition than these poor but hardy islanders. Yet there is not a region of the world that has been more frequently or terribly scourged than this semibarren island. The best known volcano in Iceland is Mt. Hecla, which ranks with Ætna and Vesuvius in fame. It is not the highest nor most remarkable of Icelandic volcanoes; but the frequency of its eruptions, together with the fact that it may be easily reached, have brought it to the front. It is five thousand feet high, and lies but thirty-five miles from the sea. The larger portion of the material thrown out by it consists of slag, cinders, pumice, and ashes, the slope of its cone being about 35 degrees. It has nothing answering to the customary crater; the eruptions break from fissures in its sides; and, in consequence, it may emit several streams or showers at once. Hecla has been in eruption about thirty times since its character was first known, and has at times made fearful havoc. Its last great outbreak was in 1878. Hecla has adjutants in this volcanic field that are more savage and relentless than the generalissimo. One of the most destructive outbursts of recent times occurred in the Vatna district in 1875. In this region, about sixty [Illustration: MT. HECLA.]
