Whilst the latter is soft I insert the macadam 

 cubes, fitting them closely into contact and 

 pressing them down, but leaving their upper 

 sides slightly higher than the bricks. When 

 the space is filled I go over it with a board and 

 a mallet, beating down the cubes until they 

 are all level with the bricks. The exuding 

 mortar is transferred to the next space, and 

 that one similarly treated until the whole 

 path is finished. After allowing an hour 

 for the mortar to partly set, the path surface 

 may be washed over with a stiff brush and 

 clean water, to remove the mortar which clings 

 to the top of the stone cubes. In twelve hours 

 the path will be set and as firm as a rock, 

 the mortar used for the mosaic work 

 taking hold of the bricks and tying the whole 

 together.

 appearance is to fill in the spaces with cement 

 concrete, finishing with a rendering of cement. 



Cobble stones make an excellent filling, and 

 give quite an old-world appearance to a path. 

 They should be laid on end in dry sand, levelled 

 by the use of the board and mallet, and then 

 grouted with liquid cement poured amongst
