 The running bond is the simplest of the six patterns, consisting of all stretchers. Because the bond has no headers, metal ties usually form the structural bond. The running bond is used largely in cavity wall construction, brick veneer walls, and facing tile walls made with extra wide stretcher tile.  The common, or American, bond is a variation of the running bond, having a course of full-length headers at regular intervals that provide the structural bond as well as the pattern. Header courses usually appear at every fifth, sixth, or seventh course, depending on the structural bonding requirements.

Advantages: they are fireand weather resistant, they are easy to transportate, in production and in laying. Disadvanges: they can only be used in conjuction with mortar, since they are too small, too light an too irregular to be stabilized by weight.

__<span style="font-family: 'Comic Sans MS',cursive;">**Thoughts on the use of brick in construction and public spaces.** __ <span style="font-family: 'Comic Sans MS',cursive;">Bricks have been used troughout history, weather because of their low prices or because of their shape and weight. Nowadays they are widely used to create different shapes such as columns and arches. They also bring, in conjuction with mortar, a lot of stability to the structures, so they are perfect for creating public spaces. <span style="font-family: 'Comic Sans MS',cursive;">media type="file" key="ale bricks.mp3" width="240" height="20"

Comparison and contrast:** Brick __compares__ favorably with stone as a structural material for its fire-and-weather resisting qualities and for the ease of production, transportation and laying. <span style="font-family: 'Comic Sans MS',cursive;">**b. Description:** The unit __is__ too small, too light, and too irregular. <span style="font-family: 'Comic Sans MS',cursive;">**c. Exemplification:** __For example__, wedge-shaped bricks are sometimes employed in arch construction and bricks with rounded faces in columns. <span style="font-family: 'Comic Sans MS',cursive;">**d. Cause/Effect:** Bricks may be used in construction only in conjunction with mortar, __since__ the unit is too small, too light, and too irregular to be stabilized by weight. <span style="font-family: 'Comic Sans MS',cursive;">** e. Chronology: **Brick which has been used __since__ the 4th millenium BC, was the chief building material in theancient Near East.
