“ Moles vary in color. Those we are familiar 
with are of the peculiar grayish-brown tint, rec¬ 
ognized everywhere as 4 moleskin.’ Black moles, 
however, are not uncommon; there is a white spe¬ 
cies, too, and the cape or golden mole is often of a 
decidedly orange hue. In Germany, the mole is 
termed the moltwerf: from the words molde , dirt, 
and werfen , to throw. It seems a happy combi¬ 
nation, for certainly nothing can throw dirt with 
greater zeal than the mole, unless perchance it 
may be the woodchuck.”
