CHAPTER XX.
THE OLD GARDEN.
The avenue seemed to Donal about to stop dead against a high wall, but ere they quite reached the end, they turned at right angles, skirted the wall for some distance, then turned again with it.

It was a somewhat dreary wall--of gray stone, with mortar as gray--not like the rich-coloured walls of old red brick one meets in England.

But its roof-like coping was crowned with tufts of wall-plants, and a few lichens did something to relieve the grayness.

It guided them to a farm-yard.

Mr.Graeme left his horse at the stable, and led the way to the house.
They entered it by a back door whose porch was covered with ivy, and going through several low passages, came to the other side of the house.
