"When a man so constituted had once mastered his craft of letters, he might take up whatever instrument he pleased with the instinctive and just confidence that he would play upon it to a tune and with a manner of his own. This is indeed the true mark and test of his originality. He has no need to be, or to seem, especially original in the form and mode of literature which he attempts. By his choice of these he may at any time give himself and his reader the pleasure of recalling, like a familiar air, some strain of literary association; but in so doing he only adds a secondary charm to his work; the vision, the temperament, the mode of conceiving and handling, are in every case personal to himself. He may try his hand in youth at a _Sentimental Journey_, but R. L. S. cannot choose but be at the opposite pole of human character and feeling from Laurence Sterne. In tales of mystery, allegorical or other, he may bear in mind the precedent of Edgar Poe, and yet there is nothing in style and temper much wider apart than _Markheim_ and _Jekyll and Hyde_ are from the _Murders in the Rue Morgue_ or _William Wilson_. He may set out to tell a pirate story for boys 'exactly in the ancient way,' and it will come from him not in the ancient way at all, but re-minted; marked with a sharpness and saliency in the characters, a private stamp of buccaneering ferocity combined with smiling humour, an energy of vision and happy vividness of presentment, which are shiningly his own. Another time, he may desert the paths of Kingston and Ballantyne for those of Sir Walter Scott; but literature presents few stronger contrasts than between any scene of _Waverley_ or _Redgauntlet_ and any scene of the _Master of Ballantrae_ or _Catriona_, whether in their strength or weakness: and it is the most loyal lovers of the older master who take the greatest pleasure in reading the work of the younger, so much less opulently gifted as is probable--though we must remember that Stevenson died at the age when Scott wrote _Waverley_--so infinitely more careful of his gift. Stevenson may even blow upon the pipe of Burns and yet his tune will be no echo, but one which utters the heart and mind of a Scots maker who has his own outlook on life, his own special and profitable vein of smiling or satirical contemplation.
