Here he lived about four years, undetermined what course of life he should pursue; but at length, having resolved to repair as a free trader to Hindostan, he proceeded to London in 1753 for the purpose of soliciting permission from the directors. An event now occurred, however, which promised to determine for ever the current of his hopes and pursuits. Conceiving an attachment for the daughter of an eminent wine-merchant, who, on dying, had bequeathed considerable wealth and a thriving business to his widow and child, Bruce relinquished his scheme of pushing his fortunes in the East, married, and became himself a wine-merchant. But Providence had otherwise disposed of his days. In a few months after his marriage, consumption, that genuine pestilence of our moist climates, deprived him of his amiable wife at Paris, whither he had proceeded on his way to the south of France. For some time after this event he continued in the wine trade, the interests of which requiring that he should visit Spain and Portugal, he applied himself during two years to the study of the languages of those countries, of which he is said to have possessed a very competent knowledge.
This preliminary step having been made, he may be said to have commenced his travels with a voyage to the Peninsula. Landing on the northern coast of Spain, he traversed Gallicia, spent four months in Portugal, and then, re-entering Spain, made the tour of a large portion of Andalusia and New Castile, and then proceeded to Madrid. His enthusiasm and romantic character, which had probably a new accession of ardour from the wild scenes still redolent of ancient chivalry which he had just visited, recommended him strongly to the Spanish minister, who used many arguments to induce him to enter the service of his Catholic majesty. This by no means, however, coincided with Bruce’s views. That restlessness which the man who has once conceived the idea of travelling ever after feels, unfitted him in reality for all quiet employment. He felt himself goaded on by the desire of fame; to be in motion seemed to be on the way to acquire it. He therefore proceeded across the Pyrenees into France, and thence, through Germany and Holland, to England, where he arrived in July, 1758.
