The muskrat is common in Harding County. Half a century ago Visher
(1914:89) noted that it was "Fairly plentiful along the streams having
deep permanent 'holes'."
Seven adults, all in winter pelage, were taken late in March from a pond
near the west side of Slim Buttes (5 mi. S and 14 mi. E Buffalo). Testes
of three adult males measured 17, 19, and 22; of three females, none
evidenced reproductive activity.
