be used after mordanting \\ith chrome alum. Direct dyes, 

 natural dyestuffs and pigment dyes are also used. The goods 

 are struck out after dyeing, lightly fat liquored with com- 

 mercial egg yolk, dried out at 110 to 120 F., staked and 

 fluffed on the face side. 



Buff leather is a similar leather made from hides. They 

 are limed mellow for a fortnight, unhaired, fleshed, and then 

 limed again for another week in sharp limes. The grain is 

 then split off, and the goods rinsed and scudded, slightly 

 delimed and hung up to dry. They are then treated in 

 much the same way as fleshes for chamois, but lime is often 

 added to the cod oil used in stocking. 



Buck leather is a similar product obtained from deerskins, 

 but much mock buck is made from cheaper raw material.
