Suddenly he sat up straight, twisted his head sideways, as a dog does
when he sees the most interesting thing of his life, dropped his
tongue out a bit, and looked intently. I looked too, and there, just
below, was old Roby, the best foxhound in a dozen counties, creeping
like a cat along the top rail of a sheep-fence, now putting his nose
down to the wood, now throwing his head back for a great howl of
exultation.--It was all immensely entertaining; and nobody seemed to
be enjoying it more than the fox.

One of the most fascinating bits of animal study is to begin at the
very beginning of fox education, _i.e._, to find a fox den, and go
there some afternoon in early June, and hide at a distance, where you

interrogation points, and back again. For hours at a stretch they roll
about, and chase tails, and pounce upon the quiet old mother with
fierce little barks. One climbs laboriously up the rock behind the
