terror. But when any whole nation becomes the victim of the destructive powers of exterior agents, then indeed man shrinks into insignificance, he feels his tenure of life insecure, his inheritance on earth cut off.
I remember, after having witnessed the destructive effects of a fire, I could not even behold a small one in a stove, without a sensation of fear. The mounting flames had curled round the building, as it fell, and was destroyed. They insinuated themselves into the substances about them, and the impediments to their progress yielded at their touch. Could we take integral parts of this power, and not be subject to its operation? Could we domesticate a cub of this wild beast, and not fear its growth and maturity?
Thus we began to feel, with regard to many-visaged death let loose on the chosen districts of our fair habitation, and above all, with regard to the plague. We feared the coming summer. Nations, bordering on the already infected countries, began to enter upon serious plans for the better keeping out of the enemy. We, a commercial people, were obliged to bring such schemes under consideration; and the question of contagion became matter of earnest disquisition.
That the plague was not what is commonly called contagious, like the scarlet fever, or extinct smallpox, was proved. It was called an epidemic. But the grand question was still unsettled of how this epidemic was generated and increased. If infection depended upon the air, the air was subject to infection. As for instance, a typhus fever has been brought by ships to one seaport town; yet the very people who brought it there, were incapable of communicating it in a town more fortunately situated. But how are we to judge of airs, and pronounce—in such a city plague will die unproductive; in such another, nature has provided for it a plentiful harvest? In the same way, individuals may escape ninety-nine times, and receive the deathblow at the hundredth; because bodies are sometimes in
