A trap Y and an 76 DISTILLATION OF ALCOHOL. air pipe Z provide means for the escape of gas. As before stated, the form of perforations inthe plates of a column through which the vaporpass upward through the beer or wash is particularlyimportant. The steam must be thoroughly diffusedthrough the beer, or else particles of mash arecarried up, accumulate around the perforations,baking there and clogging them up. The clogging.

Thus the operatingcapacity of the still is reduced and a larger quantityand greater pressure of steam is necessary withconsequent waste of fuel. It is necessary then that the form ot perforationor trap through which the vapor ascends should
