SHEEPSKINS 119 



20-30 minutes at 95 F. ; after washing they are " soured " 

 in weak (J per cent.) sulphuric acid solution, and retanned 

 with sumach paste for an hour, drumming at 100 F. They 

 may then be finished for basils, moroccos or roller leather as 

 described above, but are often finished as imitation glace 

 kid. In this case they are drum dyed, lightly fat- 

 liquored (see Part III., Section IV., p. 163), struck out and 

 dried. They are staked by machine, fluffed, seasoned and 

 glazed. They may be re-staked and reglazed if desired.
