Take two good-sized hearts of fine romaine; remove the outer greens; wipe, washing it carefully. Drain, then place it in a salad-bowl, sprinkling over a teaspoonful of chopped chives, half a teaspoonful of chopped chervil, the same of tarragon, and season with one pinch of salt, and half a pinch of pepper, diluted in a wooden salad-spoonful of vinegar, and one and a half spoonfuls of sweet oil. Mix thoroughly together, and serve immediately.
