He was scarcely fifteen years old when all the domestics who were attached to his interest, or who enjoyed any share of his confidence, were removed from under his roof by the jealous government. He remonstrated with energy beyond his years, but in vain. Vigilant observers saw the tears more than once rise in the eyes of the young state prisoner. His health, naturally delicate, sank for a time under the emotions which his desolate situation had produced. Such situations bewilder and unnerve the weak, but call forth all the strength of the strong. Surrounded by snares in which an ordinary youth would have perished, William learned to tread at once warily and firmly. Long before he reached manhood he knew how to keep secrets, how to baffle curiosity by dry and guarded answers; how to conceal all passions under the same show of grave tranquillity. Meanwhile he made little proficiency in fashionable or literary accomplishments. The manners of the Dutch nobility of that age wanted the grace which was found in the highest perfection among the gentlemen of France, and which, in an inferior degree, embellished the court of England; and his manners were altogether Dutch. Even his countrymen thought him blunt. To foreigners he often seemed churlish. In his intercourse with the world in general he appeared ignorant or negligent of those arts which double the value of a favor and take away the sting of a refusal. He was little interested in letters or science. The discoveries of Newton and Liebnitz, the poems of Dryden and Boileau, were unknown to him. Dramatic performances tired him, and he was glad to turn away from the stage and to talk about public affairs, while Orestes was raving, or while Tartuffe was pressing Elmira’s hand. He had, indeed, some talent for sarcasm, and not seldom employed, quite unconsciously, a natural rhetoric, quaint, indeed, but vigorous and original. He did not, however, in the least affect the character of a wit or of an orator. His attention had been confined to those studies which form strenuous and sagacious men of business. From a child he listened with interest when high questions of alliance, finance, and war were discussed. Of geometry he learned as much as was necessary for the construction of a ravelin or a horn-work. Of languages, by the help of a memory singularly powerful, he learned as much as was necessary to enable him to comprehend and answer without assistance everything that was said to him and every letter which he received. The Dutch was his own tongue. With the French he was not less familiar. He understood Latin, Italian, and Spanish. He spoke and wrote English and German, inelegantly, it is true, and inexactly, but fluently and intelligibly. No qualification could be more important to a man whose life was to be passed in organizing great alliances, and in commanding armies assembled from different countries.
