Note 1 — MIND OR INSTINCT.

Some animals are self-taught. The mocking-bird whistles for the dog; Cæsar starts up and runs to meet his master. He squeaks out like a hurt chicken, and the hen hurries about with hanging wings and bristling feathers, clucking to protect her injured brood. The barking of the dog, the mewing of the cat, the creaking of the passing wheel-barrow, follow with great truth and rapidity. He repeats the tune taught him by his master, though of considerable length, fully and faithfully. He runs over the quiverings of the Canary and the clear whistlings of the Virginia nightingale, or red-bird, with such superior execution and effect, that the mortified songsters feel their own inferiority, and become silent, while he seems to triumph in their defeat by redoubling his exertions.—Wilson.
