A perpetual and hurrying change is visible in all things.

A few showers, and the surface of the earth is teeming with verdure; a few days of drought, and the seeds already formed are falling to the earth, springing in their turn to life at the approach of moisture.

The same rapidity of change is exhibited in their decay.

The heaps of vegetable putridity upon the banks of rivers, when a swollen torrent has torn the luxuriant plants from the loosened soil, are but the effects of a few hours' change.

The tree that arrives at maturity in a few years rots in as short a time when required for durability: thus it is no mystery, that either a house or a city should shortly fall to decay when the occupant is gone.
In like manner, and with still greater rapidity, is a change effected in the face of nature.
