There are few more interesting thoroughfares in the world than this avenue. Here ruler and ruled jostle each other; here thunder the liveried equipages of foreign nobles; here saunters the President, and nobody turns to look. Sooner or later all the famous of the world are tolerably sure to be met upon it: as we walk there History walks beside us and mighty shadows move before us. Washington has dashed down that avenue in his yellow chariot that was painted with cupids and drawn by six white horses; Hamilton, Jefferson, La Fayette, Burr, and all the gods of the republic have trodden it before us; dishonoring British squadrons have marched upon it; it has shaken to the tread of our own legions; and great forms begin to loom in the national memory that have just passed from its daily crowds. Nor does all its interest belong to the past: those daily crowds themselves are full of perpetual dramas in which the actors are unknown perhaps to fame or fiction, but none the less real and in sad earnest with their play. Here goes a little withered man in his threadbare coat: he has a proud and scowling face, but he pauses with a singularly sweet and gentle manner at every group of children, black or white. He is an old numismatician, a foreigner, and his youth in Europe was given to the gathering of coins and medals till he had a nearly unrivaled collection, and he came over the sea, hoping to dispose of them to the government of this country. Failing in his purpose, his means dwindling day by day, he was obliged to pledge a portion of his treasure that he might be able to live. It cut him to the heart to divide the collection: he had the history of the world in those incontrovertible records of brass and silver and gold, currency of the old Hindoo, of the Assyrian--medals where Alexander's superb profile shone crowned as Apollo--coins of the Ptolemies, of the Cæsars, of almost every people and generation from the beginning of civilization till to-day. But divide them he did, and left a part of them in other hands, and went to the North. There, driven by necessity, he pledged another portion; and after a while, wishing to redeem the latter pledge, and not being allowed to do so, he began a lawsuit to obtain it. The court decided the case against him; and the little man, half crazed, unable to obtain the portion he had pledged in Washington, and now seeing this also leave him, cried out in the open court, "O unjust judge! God shall demand your soul of you!" And the judge, with a sudden exclamation, fell backward, and before the sun set he was dead. The little numismatician returned to Washington, and having failed in all the hopes of his life, took translating and any other writing he could find to do. But there a certain high official having treated him unworthily, he adjured him much as he had adjured the unjust judge; and a fortnight afterward the official had gone to join the judge. It
