To make the tan liquor, dissolve 2 ounces of salt and 2 ounces of 

 powdered alum in a quart of boiling water. Wlaen this is cool add 

 slowly, while stirring, 4 ounces commercial sulphuric acid and then 

 2 ounces washing soda {not "cooking" soda). The liquor is ready to. 

 use when cold and keeps well in bottles; but the bottles will burst if 

 tightly corked at first.

In thin skins, two, and in thick skins three, coats of the tan liquor 

 should be applied at six-hour intervals. After the last application 

 of tan liquor the pelt should be hung up for ten hours. ~ The entire 

 skin should then be soaked for ten minutes in a neutralizing solution 

 made by dissolving a handful of washing soda in half a gallon of cold 

 water. This will neutralize any acid that may remain in the pores of 

 the skin. The acid would in time weaken the skin if left unneutralized. 

 The skin should then be thoroughly rinsed in clear cold water. A couple 

 of light sticks, with the ends sharpened and placed in the pads of the 

 feet (figure 1. 6) will keep the legs extended and insure uniform 

 drying.
