Fes., 1912. MAMMALS OF ILLINOIS AND WISCONSIN — Cory. 255 
except on the lower back, hips, and sides of base of tail where they 
are longest; quills blackish at tip, whitish at base, the largest ones 
having a length of from 3 to 4 inches, they lie flat but can be erected 
by muscular contraction; incisors deep orange. 
Measurements — Total length, about 35 in. (890 mm.); tail, 5.50 to 
6.50 in. (152 mm.); hind foot, 3.50 in. (90 mm.). 
At the present time the range of the Porcupine within our limits 
is restricted to northern Wisconsin, but in early days it probably 
extended considerably farther south. Porcupines are still common 
in the forested regions from Marathon County, Wisconsin, northward, 
and individuals are occasionally seen in Wood, Jackson, Clark and 
Buffalo counties, which appear to be about the southern limits of 
their present range in the state. 
I have been unable to find any satisfactory proof of its occurrence 
in Illinois, although in early days it is not unlikely that it may have 
inhabited some of the northern counties. Kennicott writes, “I am 
not aware that it has been observed in northern Illinois, although it 
is said to inhabit Whiteside County and the banks of the Illinois River”’ 
(l. ¢., p. 91). I have been informed that years ago it was occasionally 
found in Jo Daviess County, but upon investigation the evidence 
proved unsatisfactory. Nevertheless, Mr. Edward Grimm of Galena 
writes me, he believes it was formerly found in that county. In Indiana, 
however, its range is known to have extended to the southern portion 
of the state, and it was apparently not uncommon in several of the 
extreme western counties in close proximity to Illinois. The Prince 
of Wied states that it was rare in Posey County at the time of his 
visit to New Harmony in 1832. Evermann and Butler cite numerous 
records for Indiana, the latest being a specimen taken in Grant County, 
in 1892 (1. ¢., p. 125); but Hahn believes it probably survived along 
the Kankakee River a few years later (J. c., p. 532). Mr. E. J. Chansler 
of Bicknell, Indiana, writes me that old men told him Porcupines were 
common in Knox County in early days, and that Mr. T. F. Chambers 
saw one near Chambers Pond in that county in 1864. There are two 
specimens in the State Museum at Indianapolis claimed to have been 
taken in Laporte County, Indiana, but the date is not given. Dr. John 
T. Plummer states that several Porcupines were killed in the suburbs 
of Richmond, Wayne County, Indiana, and that he had a fine speci- 
men in his collection captured near the town (Amer. Journ. Sci. & 
Arts, XLVI, 1844, p. 248). 
The Porcupine is an inhabitant of the forests and spends the greater 
part of its time in trees. When on the ground its movements are slow 
and clumsy, and it appears to have little fear of man, which often leads 
to its undoing, as its sharp pointed quills, which are held in great
