In quiet weather mesa days have no parallel for stillness, but the
night silence breaks into certain mellow or poignant notes. Late
afternoons the burrowing owls may be seen blinking at the doors of
their hummocks with perhaps four or five elfish nestlings arow, and
by twilight begin a soft whoo-oo-ing, rounder, sweeter, more

vitals at a thousand yards, is both bold and curious. Not so bold,
however, as the badger and not so much of a curmudgeon. This
short-legged meat-eater loves half lights and lowering days, has
