tan, but also assists in setting out. Sumaching may be 

 for several days, merely overnight or even only for a few 

 hours, being stoned after wetting back to temper. Hand- 

 stuffed goods get a coat of cod oil first, and during the drying 

 are often well set out. Drum-stuffed goods are well set 

 out by machine, and after some drying, stoned and reset 

 by hand. It is now usual to buff the grain, i.e. remove the 

 coarser parts by light shaving. This prevents cracking in 

 the finished article. The goods are blacked with logwood, 

 iron and ammonia, thinly dubbined again, again well set 

 out and tallowed. Setting out, indeed, may be done at 

 any convenient opportunity. The superfluous grease is 

 removed by slicking, scraping, brushing with a stiff brush, 

 and finally with a soft brush. 



For brown harness the goods are more carefully selected, 

 more thoroughly scoured and sumached, and bleached 

 frequently with oxalic acid. They are hand stuffed, stained 

 twice, and after the usual setting out, glassing and brushing, 

 are finally rubbed with flannel. 



For bridle leather the goods are carefully shaved but 

 are not stuffed, being merely oiled with cod oil on flesh and 

 grain. They are dried out before scouring, and then sized, 

 set out, stained and resized. The goods are heavily glassed 

 during the finishing.
