FARM BUILDINGS IN SOUTH AFRICA 



Advantages of English Garden Bond. — If we look at the face of a wall 

 built in English bond we notice that the overlap of bricks in any one 

 course, beyond bricks in the courses immediately above or below that one, 

 amounts to | brick or 2\ inches. 



Now examine the figures illustrating English garden or Colonial 

 bond, and it will be seen that only half of the courses overlap by £ brick, 

 the remainder overlapping by \ brick or 4£ inches. This is claimed as 

 an advantage, since farm buildings are often erected by labour not fully

skilled, and, in the case of Colonial bond, there is more overlap to come 

 and go upon (in at least half the courses) than is the case in English 

 bond. This lessens weakening of the wall due to inaccurate placing of 

 the bricks in a horizontal direction. For instance, if a brick in English 

 bond be out of place to the extent of 1 inch horizontally, the overlap is 

 reduced to only \\ inches, but in Colonial bond— in the case of at least 

 50 per cent, of the courses —the overlap would still be as much as 

 Z\ inches.
