Shortly after the conclusion of this tour he accompanied his pupil in a little excursion to Calais, when he enjoyed the satisfaction, which none but a traveller can appreciate, of treading for the first time on foreign ground. In 1792 he was fortunate enough to obtain an engagement to travel with Lord Berwick, whom he had known at college, and in the autumn of that year set out in company with that young nobleman, through Germany and Switzerland into Italy. He was now in the position for which nature had originally designed him. “An unbounded love of travel,” says he, “influenced me at a very early period of my life. It was conceived in infancy, and I shall carry it with me to the grave. When I reflect upon the speculations of my youth, I am at a loss to account for a passion which, predominating over every motive of interest and every tie of affection, urges me to press forward and to pursue inquiry, even in the bosoms of the ocean and the desert. Sometimes, in the dreams of fancy, I am weak enough to imagine that the map of the world was painted in the awning of my cradle, and that my nurse chanted the wanderings of pilgrims in her legendary lullabies.” This was the spirit which urged the Marco Polos, the Chardins, and the Bruces to undertake their illustrious journeys; and if Clarke was compelled by circumstances to confine his researches to less remote and better known countries, he exhibited in his rambles through these a kindred enthusiasm, and similar devotion and energy.
