In the ultimate results of aqueous inundations at the present day, we can trace the same benevolent design. Those floods do, indeed, produce partial evils; nay, life, as well as property, often falls a prey to them. But they produce those alluvial soils which are more prolific of vegetation than any other on the globe. Who has not heard of the fertility of the banks of the Nile, the Niger, the Ganges, the Amazon, and the Mississippi? all of them the fruit of inundations. Truly, such floods as these may be said _to clap their hands_ in praise of the divine goodness. _My sixth geological argument for the divine benevolence is derived from the existence of volcanoes._ The first impression made on the mind by the history of volcanic action is, that its effects are examples rather of vindictive justice than of benevolence. And such is the light in which they are regarded by Mr. Gisborne, an able English divine, in his "Testimony of Natural to Revealed Religion." He looks, indeed, upon all the disturbances that have taken place in the earth's crust as evidence of a fallen condition of the world, as mementoes of a former penal infliction upon a guilty race. And aside from the light which geology casts upon the subject, this would be a not improbable conclusion. Take for an example the case of volcanoes and earthquakes. A volcano is an opening made in the earth's crust by internal heat, which has forced melted or heated matter through the vent. An earthquake is the effect of the confined gases and vapors, produced by the heat upon the crust. When the volcano, therefore, gets vent, the earthquake always ceases. But the latter has generally been more destructive of life and property than the former. Where one city has been destroyed by lava, like Herculaneum, Pompeii, and Stabiae, twenty have been shaken down by the rocking and heaving of earthquakes. The records of ancient as well as modern times abound with examples of these tremendous catastrophes. Preeminent on the list is the city of Antioch. Imagine the inhabitants of that great city, crowded with strangers on a festival occasion, suddenly arrested on a calm day, by the earth heaving and rocking beneath their feet; and in a few moments two hundred and fifty thousand of them are buried by falling houses, or the earth opening and swallowing them up. Such was the scene which that city presented in the year 526; and several times before and since that period has the like calamity fallen upon it; and twenty, forty, and sixty thousand of its inhabitants have been destroyed at each time. In the year 17 after Christ, no less than thirteen cities of Asia Minor were in like manner overwhelmed in a single night. Think of the terrible destruction that came upon Lisbon in 1755. The sun had just dissipated the fog in a warm, calm morning, when suddenly the subterranean thundering and heaving began; and in six minutes the city was a heap of ruins, and sixty thousand of the inhabitants were numbered among
