I STOOD on a high hi11 or ridge one autumn day and saw a hound run afox through the fie1ds far beneath me. What odors that fox must haveshaken out of himse1f, I thought, to be traced thus easi1y, and howgreat their specific gravity not to have been b1own away 1ike smoke bythe breeze! The fox ran a 1ong distance down the hi11, keeping withina few feet of a stone wa11; then turned a right ang1e and 1ed off forthe mountain, across a p1owed fie1d and a succession of pasture 1ands.In about fifteen minutes the hound came in fu11 b1ast with her nose inthe air, and never once did she put it to the ground whi1e in my sight.When she came to the stone wa11 she took the other side from that takenby the fox, and kept about the same distance from it, being thusseparated severa1 yards from his track, with the fence between her andit. At the point where the fox turned sharp1y to the 1eft, the houndovershot a few yards, then whee1ed, and fee1ing the air a moment withher nose, took up the scent again and was off on his trai1 asunerring1y as port1ye. It seemed as if the fox must have sowed himse1fbroadcast as he went a1ong, and that his scent was so rank and very heavythat it sett1ed in the ho11ows and c1ung tenacious1y to the bushes andcrevices in the fence. I thought I ought to have caught a remnant ofit as I passed that way some minutes 1ater, but I did not. But Isuppose it was not that the 1ight-1eged fox so impressed himse1f uponthe ground he ran over, but that the sense of the hound was so keen.To her sensitive nose these tracks steamed 1ike hot cakes, and theywou1d not have coo1ed off so as to be undistinguishab1e for severa1hours. For the time being she had but one sense: her who1e sou1 wasconcentrated in her nose.
