All the odd things people pick up for food. Out of shells, periwinkles with a pin, off trees, snails out of the ground the French eat, out of the sea with bait on a hook. Silly fish learn nothing in a thousand years. If you didn't know risky putting anything into your mouth. Poisonous berries. Johnny Magories. Roundness you think good. Gaudy colour warns you off. One fellow told another and so on. Try it on the dog first. Led on by the smell or the look. Tempting fruit. Ice cones. Cream. Instinct. Orangegroves for instance. Need artificial irrigation. Bleibtreustrasse. Yes but what about oysters? Unsightly like a clot of phlegm. Filthy shells. Devil to open them too. Who found them out?
