over from b 1 under i 4 . The cord now forms a sort of spiral worm round andthrough the machinery and cisterns, beginning at b c, and ending at the top ofb 1 to i 4 , the number of revolutions being governed by the number ofdivisions in the racks d and d 1 , so that if there were fifteen divisions in eachrack there would be fifteen revolutions under c, round B, through g, under e,through d, and fifteen revolutions over c, round b 1 , over i 3 , through d 1 andg 1 , under e 1 , over i 2 , and again over c, passing from the top of b 1 to i 4 ; andby this means, if one end of the goods marked k, and placed upon the seriesof rollers f, is fastened to the end of the guide cord, the goods will, when thecalender is put in motion, be conduced and washed thirty times through thewater in the cisterns, and squeezed thirty times through the calenders. Asthe operation proceeds and the guide-cord passes through the calender, it iswound by hand upon roller a to prevent it from becoming entangled, and tokeep it in readiness for the next operation. As soon as the first end of the

goods arrives at the guide-roller i 4 it is detached from the end of the guide-cord and attached to the guide-cord at the other end, or with the opposite set.of calenders. After this, by putting these in motion, the goods are washedand squeezed through its cisterns, supplied with hot and strong lime-lye, andthe goods passing over guide-roller i e are conveyed over other guide-rollers tobe placed for the purpose, and taken down by some person or by propermachinery into one of the boiling vessels, where they are suffered to remainwhile the lime-boiling is effe&ed.
The goods are saturated with the solutions by the aid of an apparatusshown in Fig. 4, being designed to supply continuous rapid motion andpressure to obviate the danger of rotting from still soaking, b b b are thewashing rollers; c c c are the gear or speed rollers; e e e are rollersimmersed in as many divisions of the cistern G, Fig. 3.
