Buckling
The seamy, unsightly scars to be seen on some castings when too much slicking and too little venting have been expended on clayey loam or sand. When due attention to these shortcomings fails to work an improvement, it is evidence conclusive that more fire-sand is needed in the facing-sand. See SLICKER; SCABBED CASTINGS; VENTING; RAMMING; FACING-SAND. Buckle-chain. See SWIVEL-CHAIN.
