The first concert was announced for the evening of September 11th, and it was to take place in the great hall of Castle Garden, afterward famous as the landing-place for emigrants at New York. The tickets for this occasion were sold at auction, and the first one was bid up to the extraordinary figure of $225. This was bid and the ticket was secured by John N. Genin, a hatter; and the public notice which was thereby attracted to him was such a great advertisement for his business that within a few years thereafter he amassed a fortune. It was afterward stated that Mr. Genin was Barnum's brother-in-law, and that his high bid for this ticket was a pre-arranged job; but there was no truth in this whatever. The auction itself was regarded as an occasion of such public interest that the proprietors of the Garden, where it was held, charged a shilling admission fee to it. No less than 3,000 persons paid this fee and attended the auction, and the first day's sale aggregated 1,000 tickets, which brought a total sum of $10,141. A few days after her arrival Barnum told Miss Lind that it would be desirable to make a change in the terms of their contract, if she would consent. She was startled at this, and asked him what the change was to be. "I am convinced," replied Barnum, "that this enterprise will be far more successful than either of us anticipated. So I wish to stipulate that you shall receive not only $1,000 for each concert, beside all expenses, but also that, after taking out $5,500 per night for expenses and for my services, the balance shall be equally divided between you and me." She looked at him in utter bewilderment, unable to understand his proposition. He repeated it, and at last made her realize what it was that he proposed to do. Then she grasped him by the hand and exclaimed: "Mr. Barnum, you are a gentleman of honor; you are generous; it is just as I was told. I will sing for you as long as you please. I will sing for you in America--in Europe--anywhere!" The day before the first concert Mr. Barnum told Miss Lind that, judging by appearances, her portion of the proceeds of the first concert, over and above her fee of $1,000, would amount to at least $10,000. She immediately resolved to devote every dollar of it to charity, and forthwith sent for the Mayor of the city, under whose advice she acted in selecting the various institutions among which it was to be distributed.
