It naturally suffers from all the disad-vantages of the top compression, and, in addition, the hydraulicmachinery is contained in a deep pit, which makes it difficultto be cared for and also exposes it to slag, dirt and accidentalspirts or leaks of liquid steel. In both cases the molds have tobe made sufficiently strong and correspondingly heavier and Piping in Steel Ingots j i 3 more expensive. It is, of course, a special and simpler casewhere the whole charge is poured into one mold, as, for instance,iu making a gun of large size. 3. Compression from the Sides. In this method the top isleft open, permitting the gases to escape, and the pressure isapplied directly i
