On one of these walks, the conversation happened to turn to the perennial problem of life beyond the grave and the possibility of the dead communicating with the living. Brougham, mindful of the views maintained by his father, doubtless treated the subject lightly, if not scoffingly; but one word led to another, until finally, in what he afterward described as a moment of folly, he covenanted with his friend that whichever of them should happen to pass from earth first would, if it were at all possible, show himself in spirit to the other, and thus prove beyond peradventure that the soul of man survived the death of the body. So far as Brougham was concerned, this undertaking was speedily forgotten in the pressure of the many activities into which he plunged with all the ardor of his impetuous nature. His days were given wholly to the pursuit of knowledge; his nights to the pursuit of pleasure, as pleasure was then counted by the roystering young Scotchmen, whose favorite resort was the tavern, and whose most popular pastime was filching signs, bell handles, and knockers, and stirring the city guard to unwonted energy. Under such conditions neither the death pact nor the solemn minded youth with whom he had made it could remain long in his memory; and it is not surprising to find that with the end of college life and the removal of his boyhood's friend to India, where he entered the civil service, they soon became as strangers to each other. Brougham himself remained in Edinburgh to read for the law, and incidentally to develop with the aid of an amateur debating society the oratorical talents that were in time to make him the logical successor of Pitt, Fox, and Burke in the House of Commons. He continued none the less a lover of pleasure, some of which, however, he now took in the healthy form of long walking trips through the Highlands. In this way he acquired a desire for travel, and when, in the autumn of 1799, an opportunity came for an extended tour of Denmark, Sweden, and Norway, he grasped it eagerly. Together with the future diplomat, Lord Stuart of Rothsay, then plain Charles Stuart and the boon companion of many a pedestrian excursion, he sailed for Copenhagen late in September, and by leisurely stages made his way thence to Stockholm, alive to all the varied interests of the novel scenes in which he found himself; but encountering little that was exciting or adventurous, until, after a prolonged sojourn in the Swedish capital and a brief visit to Goeteborg, he started for Norway.
