Rock and A^ilas Counties. I have also seen tlie species in 
Jefferson and Kenosha Counties. 
Canis griseus (Sabine). 
Timber Wolf ; Gray Wolf. 
Timber wolves are quite common in the extreme northern 
counties, and it seems they are increasing in numbers. Gray 
wolves are very destructive to deer, and, also, domestic animals, 
particularly sheep. In most of the northern sections of the state 
sheep raising is impracticable, if not impossible, on account of the 
depredations of wolves. Experienced trappers and hunters in- 
form me that if the leg bones of a sheep are burned in the air, 
the odor will attract wolves a distance of fifteen to twenty-five 
miles. 
I have examined specimens, mostly skulls, taken in Ashland, 
Bayfield, Forest and Oneida Counties. This species is sometimes 
reported from southern Wisconsin, but we have seen no speci- 
mens ; it may possibly occur there during severe winters. 
Canis latrans Say. 
Prairie Wolf ; Coyote. 
The prairie wolf occurs rarely in nearly all parts of southern 
Wisconsin, east nearly to Lake Michigan ; it is reported quite com- 
mon in certain localities near the Mississippi River. Mr. J. N. 
Clark writes me that this species is "not uncommon in small num- 
bers" in Dunn County. The only specimens I have seen from the 
state were taken in Green County. 
Lutra canadensis (Schreber). 
Otter. 
Otters are of regular occurrence in northern Wisconsin, and 
sometimes the species occurs in southern Wisconsin. There was 
an otter slide on the banks of Lake Koshkonong during the sum- 
mer of 1901. Dr. H. V. Ogden has a skull taken in Racine
