Lind demanded the fee in advance and Barnum agreed; this permitted her to raise a fund for charities, principally endowing schools for poor children in Sweden. Barnum borrowed heavily on his mansion and his museum to raise the money to pay Lind but he was still short of funds; so he persuaded a Philadelphia minister that Lind would be a good influence on American morals, and the minister lent him the final $5,000. The contract also gave Lind the option of withdrawing from the tour after 60 or 100 performances, paying Barnum $25,000 if she did so. Lind and her small company sailed to America in September 1850, but she was a celebrity even before she arrived because of Barnum's months of preparations; close to 40,000 people greeted her at the docks and another 20,000 at her hotel. The press was also in attendance, and "Jenny Lind items" were available to buy. When she realized how much money Barnum stood to make from the tour, she insisted on a new agreement which he signed on September 3, 1850. This gave her the original fee plus the remainder of each concert's profits after Barnum's $5,500 management fee. She was determined to accumulate as much money as possible for her charities.
The tour began with a concert at Castle Garden on September 11, 1850, and it was a major success, recouping Barnum four times his investment. Washington Irving proclaimed, "She is enough to counterbalance, of herself, all the evil that the world is threatened with by the great convention of women. So God save Jenny Lind!" Tickets for some of her concerts were in such demand that Barnum sold them by auction, and public enthusiasm was so strong that the press coined the term "Lind mania". The blatant commercialism of Barnum's ticket auctions distressed Lind, and she persuaded him to make a substantial number of tickets available at reduced prices.
