Brick should be thoroughly wet before laying, except in freezing weather. Bricks laid with the long dimension parallel to the face of the work are called stretches, perpendicular to the face are called headers. Bats (chalk bricks) should not be used except where necessary to make corners or to form patterns on the face of the walls. Walls are bonded or tied together longitudinally by overlapping stretches in successive courses. Transverse bond is obtained by making every sixth course headers wit
