sanitary, and can be easily cleaned by simply washing down 

 with water. 



Circular tanks for water or liquid manure can be built up 

 in a manner similar to the walls, the mould in this case 

 being curved to the radius of the tank. A stout iron 

 pole is firmly fixed in the centre of the tank, and from this 

 are radius bars to the mould, which is thereby guided in 

 a circle. As there is no column to start at, the mould is 

 fitted with an enil, and a piece of triangular timber inside

this leaves a V groove down the end to form a lock when 

 a complete circuit has been made. A V groove is also cut out 

 on top of the wall round the circle, and in this is dropped 

 the re-inforcing ring, after which grout is poured in to fill 

 the groove. Succeeding rings of concrete are built up until 

 the tank is the required height. 



Almost any kind of re-inforced concrete structure can be 

 erected on these methods, and it can readily be seen that the 

 system requires the minimum of timber for moulding purposes, 

 that little skilled labour is needed, and that the scaffolding is 

 of the simplest. The practice of ramming the concrete in a 

 semi-dry state assures the greatest density and cohesion of
