It is a time of fear and peril to man and beast when the hurricane develops its giant strength, yet, contemplated apart from the probability of some fatal catastrophe, there is no scene more intensely sublime in the varied panorama of nature, than that exhibited to the senses of sight and hearing, by the dense black masses of clouds that roll in wild confusion through the air, the tumultuous aspect of the ocean, the agitation of the woods, and the voice of the tempest, varying from the melancholy wail, to the piercingly shrill cry and deafening roar, and occasionally combining every kind of intonation in its sound. However destructive these extraordinary agitations of the atmosphere—however terrible such a situation as that of Æneas on the stormy sea, helpless and hopeless, stretching his folded hands to the stars, and lamenting that he had not fallen with fierce Hector on the Ilian plains—it is unquestionable, that neither “breeze, or gale, or storm,” could be dispensed with in the economy of nature; for the various forms of life which the common air sustains, are preserved in vigor by that conflict of the elements which works occasional disaster. A variety of natural causes in operation upon the surface of the globe, and in its interior, concur to derange that constitution of the atmosphere which is alone salubrious, to vitiate the fluid, convert the medium of life and health into a cause of fever, pestilence, and death, thus changing every scene where the machinery of human existence is in movement into a Grotto del Cane, completely arresting all its wheels—an effect which would undoubtedly transpire without an antagonistic influence in constant action. In the process of supporting mankind and animals, the atmosphere is deprived of its oxygen, and exhaled in a morbid condition unfit for combustion and the sustenance of life; and the respiration of plants contributes also to its derangement. The exhalations from the low swampy regions of the earth are a further cause of deterioration, and hence the malarious mass to which the Pontine marshes, and similar districts, give birth. The provision against the reduction of the atmosphere to a universally disorganised and vitiated condition is the currents that prevail in it, which disperse and separate the poisonous ingredients, render them innocuous by bringing them into new combinations, and thus keep up that due proportion between the component parts of the aerial envelop, upon which its life-conserving property hinges, yet which the functions of life are perpetually destroying. The ordinary play of the winds, whispering in gentle breezes and rushing in powerful gales, has been ordained by the Author of life to subserve this purpose, and the dread tornado is also an efficient agent in the regeneration. In its alembic, it has been remarked, “the isolated poisons will be re-distilled; by the electric fires which it generates, their deleterious sublimations will be
