Heat oven to 450°F. Grease bottom and sides of rectangular pan, 13x9x2 inches, with shortening. In medium bowl, mix flour, 1/2 cup sugar, the baking powder and salt. Cut in butter, using pastry blender or crisscrossing 2 knives, until mixture looks like fine crumbs. Stir in milk, almond extract and eggs just until blended. Spread in pan. Sprinkle with 1 tablespoon sugar and the almonds.
