What may have been the cause of this ferocious explosion there is no explanation. Whether the real source of it may not have lain in certain facts which had occurred during the past spring, that must have rudely broken in on the peace at once of his conscience and his home, we cannot say. Certainly it does seem, as Chambers suggests, like one of those sudden outbursts of temper which fasten on some mere passing accident, because the real seat of it lies too deep for words. Some instances of the same temper we have already seen. This is a sample of a growing exasperation of spirit, which found expression from time to time till the close of his life. Let us turn from this painful subject, to one of the only notices we get of him from a stranger's hand during the summer of 1791. Two English gentlemen, who were travelling, went to visit him; one of whom has left an amusing account of their reception. Calling at his house, they were told that the poet was by the river-side, and thither they went in search of him. On a rock that projected into the stream, they saw a man employed in angling, of a singular appearance. He had a cap of fox's skin on his head, a loose great coat fixed round him by a (p. 131) belt, from which depended an enormous Highland broadsword. It was Burns. He received them with great cordiality, and asked them to share his humble dinner--an invitation which they accepted. "On the table they found boiled beef, with vegetables and barley broth, after the manner of Scotland. After dinner the bard told them ingenuously that he had no wine, nothing better than Highland whiskey, a bottle of which he set on the board. He produced at the same time his punch-bowl, made of Inverary marble; and, mixing it with water and sugar, filled their glasses and invited them to drink. The travellers were in haste, and, besides, the flavour of the whiskey to their southern palates was scarcely tolerable; but the generous poet offered them his best, and his ardent hospitality they found impossible to resist. Burns was in his happiest mood, and the charm of his conversation was altogether fascinating. He ranged over a variety of topics, illuminating whatever he touched. He related the tales of his infancy and youth; he recited some of his gayest and some of his tenderest poems; in the wildest of his strains of mirth he threw in some touches of melancholy, and spread around him the electric emotions of his powerful mind. The Highland whiskey improved in its flavour; the marble bowl was again and again emptied and replenished; the guests of our poet forgot the flight of time and the dictates of prudence; at the hour of midnight they lost their way to Dumfries, and could scarcely distinguish it when assisted by the morning's dawn. There is much naivete in the way the English visitor narrates his experience of that 'nicht wi' Burns."
