Concrete Silos 111 



are available. The different rounds of the lath should 

 lap from % to % inch, and in case any bagging is seen 

 the edges must be wired together with light wire. This 

 will prevent a great deal of annoyance to the plasterers 

 in placing the first coat of plaster. Whenever it be- 

 comes necessary to splice the ends between studding, 

 the splices must be carefully wired together. When 

 the ends are spliced on the studding and lapped 3 

 inches, this wiring is not necessary. This expanded 

 metal lath has a right and a wrong side, and the best 

 results are secured if the material is so placed that the 

 slant of the mesh is upward when looked at from the 

 inside. If, when the bottom is reached, the lath does 

 not come out even, which is usually the case, the last 

 round may be left full width in case there is enough 

 lath to allow this. Care taken in getting this lath 

 smoothly placed and carefully wired will mean the 

 saving of money later, since the plasterers can make 

 better headway where this work has been properly 

 done. 



Although the first silos of this type contained no 

 other reinforcement than the metal lath, it has since 

 been thought desirable to place additional horizontal 

 reinforcement in the form of strands of heavy wire 

 completely encircling the silo. These wire strands 

 cannot be placed until all of the inside plastering is 

 done and the studding is removed. Provision must be 

 made, however, for their attachment to the vertical re- 

 inforcement in the door post before any mortar is 

 placed. 



Means of attachment at the doors can be most easily 

 provided for by fastening short wire loops to the gas-
