ey are commonlyused at a pressure of between 35 and 50 lbs., but are sometimesrun at as low as 10 lbs. pressure. They should be able to safelystand a pressure of 70 lbs. Pressure kiers exist in tivo distinct types, (1). Those in which the circulation of the liquor is broughtabout by means of steam pressure ; the liquor being forced fromone kier to another, or into an auxiliary tank and then back intothe kier. The Barlow and Pendlebury kiers are examples of tliis class. (2). Those in which the circulation of the liquor is kept upby means of steam injectors or pumps. To this class belong mostof the modern kiers. Barlow kiers always work in pairs, the construction andarrangement of which will be seen in Fig. 3G. 76 TEXTIJ.K CHKMISTKV AND DYEINU.

After another 15 minutes boilingthe liquor is blown back into A. This alternating process is con-tinued until the goods are sufficiently boiled, usually 5 to 7 hours,when the liquor is run off tlirough H and the cloth cooled andwashed. Barlow Kiers could only be operated economically in large
