Mr. Astor's profits rolled in upon him at a rate which no one could have dreamed of, and he kept their amount a secret until he had so penetrated the frontier by his agencies that he controlled the whole trade, when he occasionally acknowledged a degree of wealth which astonished those who heard. For instance, we may state this fact in illustration: He had occasion at a certain time to use a large amount of cash, and what was very rare with him, applied to his bank for a heavy discount. The unusual circumstance and the sum demanded startled the cashier, who in a plain, business way, put the question: 'Mr. Astor, how much do you consider yourself worth?' '_Not less than a million_,' was the reply. _A million_! the cashier was overwhelmed. He supposed that he knew all his customers, and had rated Astor at hardly more than one tenth of that sum. Mr. Astor commenced at an early day to buy real estate, and the habit grew upon him until it became a passion. He was for years a leading character at sheriff and other land sales, and it was the commonest thing at such places to hear the closing words of the auctioneer: 'Last call--going, going--gone--to John Jacob Astor.' At that time many large estates were broken up, and among others, that of Aaron Burr was put into the market, and speedily became the property of Mr. Astor. It embraced a small suburban principality, whose mansion, 'Richmond Hill,' was Burr's country-seat. The whole property is now in the heart of the city and is worth millions, where once it brought thousands. Mr. Astor boldly bought those wild lands, including swamps, rocky knolls, and barren commons, which lay at waste from Canal street onward to Bloomingdale, and while others affected to laugh at his judgment, the correctness of that judgment is now quite apparent. A case similar in character is that of the late eccentric Jonathan Hunt. This man, who had accumulated a vast fortune South, was quite noted, a few years ago, for his dashing land purchases in New-York, and his relatives actually served on him a warrant _de lunatico inquirendo_, with a view of preventing him from wasting his estate. Subsequently, however, it turned out that these incessant purchases which had made him a leading man at the Merchants' Exchange, and an object of distrust to his family, were splendid operations. Poor Hunt's bid was subsequently refused by the auctioneers, on the score of insanity, while the lots he bought on Madison avenue and elsewhere, were, in fact, as speculations, superior to the operations of the most sagacious speculators.
