My boy never distinctly knew what formed that island, but as there was a mill there, it must have been made by the mill-race leaving and rejoining the river. It was enough for him to know that the island was there, and that a parrot--a screaming, whistling, and laughing parrot, which was a Pretty Poll, and always Wanted a Cracker--dwelt in a pretty cottage, almost hidden in trees, just below the end of the island. This parrot had the old Creole gentleman living with it who owned the island, and whom it had brought from New Orleans. The boys met him now and then as he walked abroad, with a stick, and his large stomach bowed in front of him. For no reason under the sun they were afraid of him; perhaps they thought he resented their parleys with the parrot. But he and the parrot existed solely to amuse and to frighten them; and on their own side of the river, just opposite the island, there were established some small industries for their entertainment and advantage, on a branch of the Hydraulic. I do not know just what it was they did with a mustard-mill that was there, but the turning-shop supplied them with a deep bed of elastic shavings just under the bank, which they turned somersaults into, when they were not turning them into the river.
