STEAM-COOKING PLANTS. 
Steam is preferable to a wood fire in cooking lime-sulphur concen- 
trate as it affords better control of the heat, but it is doubtful whether 
it would be economical to install a steam-cooking plant having a 
capacity of less than 400 gallons per cooking. 
Steam may be introduced into the mixture through either a per- 
forated or a closed pipe coil placed in the cooking tank and slightly 
above the bottom. It is generally preferable to cook by live steam 
admitted through a perforated pipe, since in cooking there is a cer-
