by fresh leach liquor and fresh extract aiid dry materials. 

 The forward handlers are fresh liquors with fresh extract. 

 This tannage is fairly typical of high-class sole leather, in 

 which the liquors are worked down the yard, but worked 

 towards the offal, which thus receives liquors with relatively 

 greater proportions of mellow tans and soluble non-tans.

2. The second type consists in a tannage of about four 

 months, in which the liquors are not worked down the butt 

 yard. In this method also there is an attempt to save 

 much of the labour in handling, first by shortening the time 

 in the handlers by one week (as compared with the above), 

 and second by fusing the two progressive handler sets into 

 two sets of equal strength, through which the goods pass 

 more slowly and with less disturbance. 



The goods go through the suspenders (io-25) in about a 

 week, rocking in the early liquors, and then into large rounds 

 of handlers (30-45) for one month. The handlers consist 

 of floaters and several dusters, in which the butts are laid 

 away with 1-3 cwt. myrabs. The goods next enter the 

 layers, of the same strength as in Type i, and in which 

 they remain the same time. The total tannage is thus 15 

 weeks, of which 10 weeks (nearly 67 per cent.) are in 



The best or fourth layer is made up from leach liquor 



and extract, and is then used successively as a third, second
