From the well known nocturnal habits of moths, and the certainty of their being destroyed by a light, a cheap and effective mode of destroying them, shown in the annexed figure. It consists of a pan of viscid matter placed upon a stake, which is set in the field of cotton at suitable distances.

When the remains of an animal or plant are exposed to the air or buried in dry earth, they generally decompose and pass off almost entirely as gasses; but when buried under water or in damp earth, their preservation is probable. Therefore, the species most likely to become fossilized are those living in water or marshes, or in the neighborhood of water or marshes.
