"King Jerome's."

"And who is he?"

"The king of the world!" shouted the maniac, still advancing with a menacing air, and so near the wagon by this time that he might almost have hit Percival with his axe.

Without pausing to hear more about the jewels, a sudden blow to the horse barely enabled us to escape the reach of our fellow-laborer before he had time to use his axe on our own formations.

In the following year, when Percival was pursuing the survey by himself, on horseback, some of the elements of this adventure were repeated, but reversed after a very odd fashion. The late Dr. Carrington, of Farmington, who told me the tale, being ten miles from home on a professional excursion, drove up to a tavern and found himself welcomed with extraordinary emphasis by the innkeeper. The Doctor was just the person he wanted to see; the Doctor's opinion was very much needed about that strange man out there; he wished the Doctor to have a talk with him, and see whether he was crazy or not. The fellow had been there a day or two, picking up stones about the lots; and some of the boys had been sent to watch him, but could get nothing out of him. This morning he wanted to go away, and ordered his horse; but the neighbors wouldn't let it be brought up, for they said he was surely some mad chap who had taken another man's horse. Thus talking, the landlord pointed out Percival, surrounded by a group of villagers, who, quietly, and under pretence of conversation, were holding him under a sort of arrest. The Doctor rushed into the circle, addressed his friend Percival by name, spoke of the survey, and thus satisfied the bystanders, who, guessing their mistake, dispersed silently. No open remonstrance was needed, and perhaps Percival never understood the adventure in which he thus unconsciously formed the principal character.

While we were in Berlin, the native town of Percival, he related to me several incidents of his earlier life. His father was discussing some geographical question with a neighbor; and the future geologist, then a boy of seven or eight, sat by listening until the ignorance of his elders tempted him to speak. "Where did you learn that?" they asked, in astonishment. With timid reluctance, he confessed that he had been reading clandestinely Morse's large geography, of which there was a copy in a society-library kept at his father's house. The book, he added, had an indescribable attraction for him; and even at that almost infantile age he was familiar with its contents. It was this reading of Morse, perhaps, which determined his taste for those geographical studies in which he subsequently became so distinguished. With him, as with Humboldt and Guyot, geography was a term of wide signification. Far from confining it to the names and boundaries of countries, seas, and lakes, to the courses of rivers and the altitudes of mountains, he connected with it meteorology, natural history, and the leading facts of human history, ethnology, and archaeology. He knew London as thoroughly as most Americans know New York or Philadelphia, and yet he had never crossed the Atlantic.

An instance of the minuteness of his geographical information was related to me by the Rev. Mr. Adam, a Scottish clergyman, long resident at Benares, but subsequently settled over the Congregational Church in Amherst, Massachusetts. On his way to visit me at New Haven, he met in the stage-coach a countryman of his, who soon opened a controversy with him respecting the course of a certain river in Scotland. The discussion had continued for some time, when another passenger offered a suggestion which opened the eyes of the debaters to the fact (not unfrequently the case in such controversies) that they were both wrong. "How long since you were there, Sir?" they asked; and the reply was, "I never was in Scotland." "Who are you, Sir?" Mr. Adam wanted to ask, but kept the question until he could put it to me. I did not feel much hesitation in telling him that the stranger must have been Percival; and Percival it was, as I afterwards learned by questioning him of the circumstance.

But we must return to Berlin, in order to hear one more of Percival's stories. Passing a field, half a mile from his early home, he told an incident connected with it, and related to his favorite study of natural history. The field had belonged to his father, who, besides being the physician of Berlin, indulged a taste for agriculture. Just before the harvest season, it became palpable that this field, then waving with wheat, was depredated upon to a wasteful extent by some unknown subjects of the animal kingdom. Having watched for the pilferers in vain by day, the proprietor resolved to mount guard by night, and accordingly ambushed himself in the invaded territory. Near midnight, he saw his own flock of geese, hitherto considered so trustworthy, approach silently in single file, make their entry between the rails, and commence transferring the wheat-crop into their own crops, after a ravenous fashion. Having eaten their fill, they re-formed their column of march, with a venerable gander at the head, and trudged silently homeward, cautiously followed by their owner, who noticed, that, on regaining his door-yard, they set up a vociferous cackle, such as he had repeatedly heard from them before at about the same hour. It was a most evident attempt to establish an alibi; it was as much as to say, "If you miss any wheat, we didn't take it; we are honest birds, and stay at home o'nights, Dr. Percival." The next morning, however, a general decapitation overtook the flock of feathered hypocrites. "It was a curious instance of the domestic goose reverting to its wild habit of nocturnal feeding," remarked my narrator, dwelling characteristically upon the natural-history aspect of the fact.

Percival was almost incapable of an irrelevancy. The survey was the business in hand, and he rarely discoursed much of things disconnected with it, except, perhaps, when we were retracing our routes, or when the labors of the day were over. Of poets and poetry he was not inclined to speak. I never heard him quote a line, either his own or another's, nor indulge in a single poetic observation concerning the objects which met us in our wanderings. Indeed, he confessed that he no longer felt disposed to write verses, being satisfied that his productions were not acceptable to the prevailing taste; although he admitted that he composed a few stanzas occasionally, in order to make trial of some unusual measure or new language. He told me that he had versified in thirteen languages; and I have heard from others that he had imitated all the Greek and German metres.

Of politics, foreign and domestic, he talked frequently, but always philosophically and dispassionately, much as if he were speaking of geological stratification. His views of humanity were deduced from a most extensive survey of the race in all its historical and geographical relations. He distinctly recognized the fact of its steady advance from one stage to another, in accordance with a plan of intellectually organic development, as marked as that detected by the geologist in the gradual preparation of the earth for the abode of our species. The slowness and seeming vacillation of man's upward movement could not stagger his faith; for if it had taken thousands of ages to make earth habitable, why should it not take thousands more to bring man to his completeness? Equally free was he from misgiving on account of the remaining presence of so much misery and wretchedness; for these he considered as the indispensable stimuli to progress. Even war, he used to say, is sometimes necessary to the welfare of nations, as sickness and sorrow plainly are to that of individuals; although, to his moral sense, the human authors of this scourge were no more admirable than the devisers of any private calamity. Improvements in knowledge he regarded as the only elements of real progress; and these he looked upon as true germinal principles, bound up organically in the constitution of the human soul. Indeed, that philosophical calmness which was characteristic of him seemed to flow in some measure from his settled persuasion that the same matchless wisdom and benevolence he recognized throughout Nature wrought with a still higher providence and a more earnest love for man and would make all things finally conduce to his welfare. It was clear that he drew a profound tranquillity from the thought that he was a part of the vast and harmonious whole.
