"There, you see," said the Doctor, nodding his head towards the retreating figure; "there's a man who in his own way knows the secret of life. Most of his days are spent in dreary, monotonous toil. He is for ever wrestling with the weather and getting scorched and frozen, and the result is that the sparse enjoyments of his life are relished with a rare gusto. He sucks his pipe of an evening with a zest which the man who lies on his back all day smoking knows nothing about. So, too, the labourer who hoes turnips for one and sixpence the day. They know the arduousness of life, which is a lesson we must all learn sooner or later. You people who have been coddled and petted must learn it, too; and for you it is harder to learn, but pleasanter in the learning, because you stand above the bare need of things, and have leisure for the adornments. We must all be fighters and strugglers, Lewie, and it is better to wear out than to rust out. It is bad to let choice things become easily familiar; for, you know, familiarity is apt to beget a proverbial offspring."
The young man had listened attentively, but suddenly he leaned from the seat and with a dexterous twitch of his whip curled it round the leg of a boy of sixteen who stood before a cottage.
"Hullo, Jock," he cried. "When are you coming up to see me? Bring your brother some day and we'll go and fish the Midburn." The urchin pulled off a ragged cap and grinned with pleasure.
"That's the boy you pulled out of the Avelin?" asked the Doctor. "I had heard of that performance. It was a good introduction to your home-coming."
"It was nothing," said the young man, flushing slightly. "I was crossing the ford and the stream was up a bit. The boy was fishing, wading pretty deep, and in turning round to stare at me he slipped and was carried down. I merely rode my horse out and collared him. There was no danger."
"And the Black Linn just below," said the Doctor, incredulously. "You have got the usual modesty of the brave man, Lewie."
"It was a very small thing. My horse knew its business--that was all." And he flicked nervously with the whip.
A grey house among trees rose on the left with a quaint gateway of unhewn stone. The dogcart pulled up, and the Doctor scrambled down and stood shaking the rain from his hat and collar. He watched the young man till, with a skilful turn, he had entered Etterick gates, and then with a more meditative face than is usual in a hungry man he went through the trees to his own dwelling.
