54 THE NATURALIST’S GUIDE. 
To mount a dried skin, first soak it in alum-water until 
it is perfectly pliable, and then mount as before. The 
water should not be too strongly impregnated with alum, 
or it will crystallize upon the hair. About a quarter of a 
pound of alum to a gallon of water are the proper propor- 
tions. Ifthe skull has been detached, replace it, or make 
an artificial one of grass or plaster to take its place. Mam- 
mals that have been preserved in alcohol may be skinned 
in the usual manner and mounted. 
To skin mammals for the fur alone, cut in a straight line 
from the inside of the knee of one hind leg to the other. 
Skin as before explained, only cut off the feet and detach 
the skull. Stretch smoothly on a thin board, with the 
wrong side out. The skin should be lengthened rather than 
widened.
