surface can be obtained. (2) the work is easier on both contractor and in- 

 spector, (3) there is no guesswork at any point of the construction, (4) under 

 similar conditions it represents a saving of from 10 to 12 cts. per square yard 

 over the old method, (5) eliminates the breaking down of the filler at a con- 

 struction crack, as each brick has a rigid support, (6) opens the field for 

 exi)eriment with thinner brick, (7) the filler is sure to reach the bottom of 

 the paving block, (8) removes need of a flush curbing, and (9) eliminates the 

 rumbling' in brick pavements."
