But it was not the big green waves or any sight in nature that drew him--he sniffed and sniffed and wriggled and twisted his black nose, and raised and depressed his ears as he sniffed, and was excited solely because the upward currents of air brought him tidings of living creatures that lurked in the rocks below--badger and fox and rabbit.

One day when quitting one of these places, on looking up I spied Jack standing on the summit of a precipice about seventy-five feet high.

Jack saw me and waved his tail, and then started to come straight down to me! From the top a faint rabbit track was, visible winding downwards to within twenty-four feet of the ground; the rest was a sheer wall of rock.

Down he dashed, faster and faster as he got to where the track ended, and then losing his footing he fell swiftly to the earth, but luckily dropped on a deep spongy turf and was not hurt.
After witnessing this reckless act I knew how he had come by those frightful bruises on a former occasion.

He had doubtless fallen a long way down a cliff and had been almost crushed on the stones.
