Nor, indeed, is it surprising that the aquatic birds, or any birds, in fact, should have a perception of the impending changes of the atmosphere. Sheep, however, when they skip and frisk with their clumsy gambols,[718] afford us similar prognostics; oxen, when they snuff upwards towards the sky, and lick[719] themselves against the hair; unclean swine, when they tear to pieces the trusses of hay that are put for other animals;[720] bees, when, contrary to their natural habits of industry, they keep close within the hive; ants, when they hurry to and fro, or are seen carrying forth their eggs; and earthworms,[721] emerging from their holes—all these indicate approaching changes in the weather. CHAP. 89.—PROGNOSTICS DERIVED FROM PLANTS. It is a well-known fact, that trefoil bristles up, and its leaves stand erect, upon the approach of a tempest. CHAP. 90.—PROGNOSTICS DERIVED FROM FOOD. At our repasts, too, and upon our tables, when we see the vessels sweat in which the viands are served, and leave marks upon the side-board,[722] it is an indication that a dreadful storm is impending.
