Crossing the Pyrenees, he went to Bordeaux, where, delighted with the cheerful vivacity of French society, he remained several months among friends and some relations who were residing there. From Bordeaux he travelled through France to Strasburg; then, following the course of the Rhine to its confluence with the Maine, he visited Frankfort. Returning to the romantic valley of the Rhine, he visited Cologne, from whence he proceeded to Brussels, the capital of the Austrian Netherlands, which country he had long been extremely desirous to examine. On the second day after his arrival, he happened to be in the company of a young man, a perfect stranger to him, who was rudely insulted. Bruce foolishly remonstrated with the aggressor, who sent him a challenge, which he accepted. They met; and Bruce, having wounded his antagonist, left Brussels immediately for Holland; whence, proceeding towards Hanover, he arrived in time to see the battle of Crevelt. This was the first military operation which he had ever witnessed. He had often boasted, and still more often dreamed, of what he was always delighted to call the _exploits_ of his ancestors, but hitherto he had only read or heard of war. The moment he became acquainted with its reality, it appeared to his excited mind to be a brilliant game, teeming with prizes and blanks; a legal gambling of life, which, by comparison, made every other employment appear trifling and insipid; and, impressed with these feelings, he resolved to forsake the peaceful life he had hitherto led, and seek adventures more congenial, as he conceived, to the spirit of his ancestors.
On his way to England he received a letter at Rotterdam informing him of the death of his father. The inestimable affection of a mother Bruce had never known; and, by the demise of his father, a man of excellent character and sound abilities, he was now deprived of all that he had ever known of parental love. He immediately proceeded to England, where he arrived in the end of July, 1758. In consequence of his father's death, Bruce succeeded to the family estate of Kinnaird, a respectable inheritance, but inadequate to the wants of his growing ambition. He did not immediately visit Scotland, being partly occupied with his concern in the wine-trade: but he gradually retired from this occupation, and in 1761, three years after his return, the partnership was legally dissolved. During this period he had been diligently employed in acquiring the Eastern languages; and, in the course of studying the Arabic (a branch of learning at that time little connected with European knowledge), he was induced to examine, in the works of Ludolf, the Ethiopic or Geez tongue, which first directed his attention to the mountains of Abyssinia. While he was thus employed, the establishment of the Carron Company in Scotland made a very considerable addition to his fortune: his property partly consisting of coal-mines, which were required by that company for the smelting of their iron.
