FAEM BUILDINGS IN SOUTH AFEICA 



Note that all the bricks composing the clamp, with the exception 

 of those forming the above-mentioned foundation layer, are to be laid 

 on edge. 



On top of the foundation the first course of " green " bricks is laid. 

 The bricks forming this layer are placed close together (close-packed), 

 without actual cramming, with their lengths at right-angles to the lengths 

 of the bricks forming the foundation course. 



The second course consists of rows of bricks laid diagonally, as shown 



I so' o" l 



Fig. 6. 



in Fig. 6, with spaces 3 inches wide between each row of bricks. These 

 spaces are filled with small fragments of coal. Eound the outside of this 

 course a row, E, of bricks is laid about 1£ inches away from the outer 

 corners of the bricks composing the main mass, and in the space between 

 fragments of coal are placed. 



The third course is similar to the second, except that the rows of 

 bricks composing it run in opposite diagonal directions to the rows of the 

 second course, thereby crossing the latter rows at right-angles.
