Soaked several days in water to remove the sizing and then dried and smoothed 
path a hot flat iron, On this surface the data is written with India ink 
using a round-pointcd pen, The ink soaks in but does not run, Such a tag 
will last a year or longer under ordinary atmospheric conditions, For longer 
Periods or under conditions where the tags come in contact with the ground they 
are coated with paraffin after labeling, This can be done by dipping in par- 
affin or, better still, keep on hand a mixture of gasoline and paraffin (pro- 
portion 1 quart of gasoline to 1/2 pound of paraffin) into which the tags can 
be dipped. The gasoline evaporates leaving a film of paraffin, Tags treated 
in this manner last oxceptionally well. Often they become coated with mud but 
after washing, the ink shows up clearly. (fF. C. Craighead.)
