It was only in company, as I have said, that all these many lights and colours could be seen in full play. He would begin no matter how--perhaps with a jest at some absurd adventure of his own, perhaps with the recitation, in his vibrating voice and full Scotch accent, of some snatch of poetry that was haunting him, perhaps with a rhapsody of analytic delight over some minute accident of beauty or expressiveness that had struck him in man, woman, child, or external nature. And forthwith the floodgates would be opened, and the talk would stream on in endless, never importunate, flood and variety. A hundred fictitious characters would be invented and launched on their imaginary careers; a hundred ingenious problems of conduct and cases of honour would be set and solved; romantic voyages would be planned and followed out in vision, with a thousand incidents; the possibilities of life and art would be illuminated with search-lights of bewildering range and penetration, sober argument and high poetic eloquence alternating with coruscations of insanely apposite slang--the earthiest jape anon shooting up into the empyrean and changing into the most ethereal fantasy--the stalest and most vulgarised forms of speech gaining brilliancy and illuminating power from some hitherto undreamt-of application--and all the while an atmosphere of goodwill diffusing itself from the speaker, a glow of eager benignity and affectionate laughter emanating from his presence, till every one about him seemed to catch something of his own gift and inspiration. This sympathetic power of inspiring others was the special and distinguishing note of Stevenson's conversation. He would keep a houseful or a single companion entertained all day, and day after day and half the nights, yet never seemed to monopolise the talk or absorb it; rather he helped every one about him to discover and to exercise unexpected powers of their own.
