will be ready in a shorter time. After the fire has 

 burnt itself out, the pile should be allowed a week 

 to cool before being opened, and the bricks will then 

 be ready for use. 



For tile-making, the clay should be prepared in 

 the same manner as for bricks, being, if anything, 

 more carefully tempered and worked up ; a more 

 tenacious character of clay being also desirable so 

 as to give greater strength, the form being more 

 fragile. Tiles are in the first instance moulded 

 perfectly flat, being afterwards bent over a cylin- 

 drical piece of wood into the requisite shape, and 

 then slipped gently off on to the ground, where 

 they are left to dry. 



Another method is as follows: the clay is 

 dabbed within the mould or frame on a board 

 previously sprinkled with brick dust, the super- 

 fluous clay being removed by means of a straight 

 bar drawn clean over the face of the mould. The 

 new tile is now slipped on to the back of one 

 previously made (the latter having been plentifully 

 sprinkled with dust to prevent cohesion), and thus 

 acquires the requisite bend or curve ; the newly- 

 formed tile is now well sanded in its turn, and the 

 next is placed on its back, and so on until a heap of 

 twenty or thirty has been formed, when a new 

 pile may be begun. These heaps are left till 

 next day, when any deficiencies in their shape are
