on Rome:
My temper is not very susceptible of enthusiasm; and the enthusiasm which I do not feel, I have ever scorned to affect. But, at the distance of twenty-five years, I can neither forget nor express the strong emotions which agitated my mind as I first approached and entered the eternal city. After a sleepless night, I trod, with a lofty step, the ruins of the Forum; each memorable spot where Romulus stood, or Tully spoke, or Caesar fell, was at once present to my eye; and several days of intoxication were lost or enjoyed before I could descend to a cool and minute investigation. My guide was Mr. Byers, a Scotch antiquary of experience and taste; but, in the daily labour of eighteen weeks, the powers of attention were sometimes fatigued, till I was myself qualified, in a last review, to select and study the capital works of ancient and modern art . . . On my return, I fondly embraced, for the last time, the miracles of Rome; but I departed without kissing the feet of Rezzonico (Clement XIII.), who neither possessed the wit of his predecessor Lambertini, nor the virtues of his successor Ganganelli.
On the edification of travel:
The use of foreign travel has been often debated as a general question; but the conclusion must be finally applied to the character and circumstances of each individual. With the education of boys, where or how they may pass over some juvenile years with the least mischief to themselves or others, I have no concern. But after supposing the previous and indispensable requisites of age, judgment, a competent knowledge of men and books, and a freedom from domestic prejudices, I will briefly describe the qualifications which I deem most essential to a traveller. He should be endowed with an active, indefatigable vigour of mind and body, which can seize every mode of conveyance, and support, with a careless smile, every hardship of the road, the weather, or the inn. The benefits of foreign travel will correspond with the degrees of these qualifications; but, in this sketch, those to whom I am known will not accuse me of framing my own panegyric.
