 must be built in flush with the wall. 



Cast-iron rain-water pipes, and even water taps, are best Recessed 

 protected by being recessed in the walls, as they are necessarily ^ojj P^P^^

more liable to be broken in stables than in other buildings. 

 The former should be in chases, built as the work progresses, 

 by inserting a piece of wood of sufficient scantling for the 

 diameter of the pipe, and building round it to the required 

 height. It will be seen in the accompanying designs that the 

 down pipes, both in and outside the buildings illustrated are 

 mostly recessed (see /, Plate 39). 



A good effect is produced for the walls of stables and coach- Rough cast, 

 houses by the use of rough castwork; the mixture for this 

 purpose is made with washed gravel, mixed with hot hydraulic 

 lime and water. This is cast upon a prepared surface from 

 large trowels whilst it is in a semi-liquid state. To prepare the 

 ground a layer of coarse stuff is " pricked up," upon which a 

 second layer of a similar kind is spread. Whilst the latter is 

 wet, and in progress, the material is thrown upon it, and forms 

 a rough coating, which is at once coloured with lime-wash and 

 ochre. 



A still better result may be obtained by what is known as "Depeter 

 " Depeter," consisting of small stones pressed into the material ^°^^* 

 whilst soft. Both of these operations may be performed on 

 the outer surface of rough brickwork, or upon brick nogging,
