The joy that the boy feels as he looks lovingly on his first knife is the joy of shaping things. The world about him has suddenly become plastic. It is a block of marble and he is the sculptor. He may make of it what he will. Until he possessed a knife, the hard inanimate substances about him defied him. He was the bird and they were the bars. But now he defies them. The knife makes all the difference. The knife is his sceptre. He is a king and all things are subject to him.

He may, of course, abuse his power. He probably will. A boy with a knife is very liable to carve his name in the polished walnut of the piano or to cut notches out of the neatly-turned legs of the dining-room table. From all parts of the world people go on pilgrimage to Westminster Abbey. And, at the Abbey, they are shown the Coronation Chair. Seated in it, all our English sovereigns have been crowned, and it is encrusted with traditions that go back to the days of the patriarchs. But a boy with a knife feels no reverence for antiquity. On the night of July 5, 1800, a Westminster schoolboy got locked in the Abbey. He curled himself up in the Coronation Chair and made it his resting-place until morning. And, in the morning, he thought of his pocket-knife. And, as the dawn came streaming through the storied eastern windows, he carved deeply into the solid oak of the seat of the chair, the notable inscription: P. Abbot slept in this chair, July 5, 1800. Thus he buried his blade in one of the noblest of our great historic treasures. It was enough to make the illustrious dead, by whom he was everywhere surrounded, turn in their ancient graves. George the Fourth and all his successors have since been crowned in a Chair that bears that impertinent record! Yet, as the chips flew, the boy felt no compunction. And, in his stolid calm, he is the type and representative of all who abuse the authority with which they are invested. He feels, as he wields the knife, that all things are at his mercy; he can shape them to his liking. He forgets that power carries its attendant obligations, and that, foremost among those obligations, is the obligation to restraint. A boy with a knife in his hand is merely a miniature edition of a man with a sword in his hand. And a man with a sword in his hand is often tempted to bury his blade in that which is even more precious than the oak of a Coronation Chair. Piano-frames and table-legs are not the only things that cry aloud for protection. The greatest lesson that the world has learned in our time is that the power of the sword involves its possessor in a responsibility that is simply frightful. The blood of brave men, the tears of good women, and the hard-earned wealth of nations must never be frivolously or lightheartedly outpoured.

From the moment at which, with sparkling eyes, that first man seized that first sharp splinter, the knife has steadily grown upon the imaginations of men. It took a thousand generations to discover its potentialities. Indeed, our own generation is only just beginning to realize the possibilities that it unfolds. Think of the marvels—I had almost said the miracles—of modern surgery.

'Let nothing share your heart with your knife!' said Dr. Ferguson to Barney Boyle, in The Doctor of Crow's Nest. The old doctor had just fallen in love with Barney. He liked his looks, he liked his temperament, and he liked his hands.

'You must be a surgeon, Barney! You've got the fingers and the nerves! A surgeon, sir! That's the only thing worth while. The physician can't see further below the skin than any one else. He guesses and experiments, treats symptoms; tries one drug and then another. But the knife, my boy!' The doctor rose and paced the floor in his enthusiasm. 'The knife, boy! There's no guess in the knifepoint. The knife lays bare the evil, fights it, eradicates it! The knife at the proper moment saves a man's life. A slight incision an inch or two long, the removal of the diseased part, a few stitches, and, in a couple of weeks, the patient's well! Ah, boy, God knows I'd give my life to be a great surgeon. But he didn't give me the fingers. Look at these!' and he held up a coarse, heavy hand. 'I haven't the touch. But you have! You have the nerve and the fingers and the mechanical ingenuity; you can be a great surgeon. You shall have all my time and all my books and all my money; I'll put you through! You must think, dream, sleep, eat, drink bones and muscles and sinews and nerves! Push everything else aside!' he cried, waving his great hands excitedly. 'And remember!'—here his voice took a solemn tone—'let nothing share your heart with your knife!'

Let nothing share your heart with your knife! That is always the knife's appeal. It is a plea for concentration. I was talking to an old gardener the other day. He was pruning his trees. The gleaming blade was in his hand and the path was littered with the wreckage of the branches. He seemed to be working a shocking havoc, and I told him so. He laughed.

'Oh, they're well-meaning things, are trees!' he exclaimed. 'They are anxious to do their best for you, but they attempt too much, far too much. Just look at this one!' and he laughed again. 'It thought it could cover all these branches with roses; and, if we left it alone, it would try. But what sort of roses would they be, I should like to know? No, no, no; it is better for them to produce fewer blossoms but to produce good ones. We mustn't let them attempt too much!'

'Let nothing share your heart with your knife!' said old Dr. Ferguson, as he urged Barney to do just one thing and to do that one thing well.

'We mustn't let the rose-trees attempt too much,' said the old gardener, as he lopped off the branches with his pruning-knife.

That seems to be the lesson that the knife is always teaching. I remember going one bright afternoon to see Gregor Fawcett of Mosgiel. Gregor was passing through a troublous and trying time. Hard on top of heavy business losses had come the collapse of his health. To my delight, however, I found him in a particularly cheerful mood.
