Preheat the oven to 350F. Butter a 9 x 13-inch baking dish with 1 tablespoon of the butter. Lightly butter the slices of bread with 1 tablespoon of the remaining butter. Lay the bread in the bottom of the baking dish and sprinkle the bread with half of the brown sugar. Enlarge the hollows of the peaches a little with a spoon. Put the peach halves on top of the bread. Place 1 teaspoon of the remaining butter in the cavity of each peach half. Sprinkle with the remaining sugar. Bake for 35-40 minutes.
