Ole Bull continued his triumphant course through Italy. At Lucca he played at the duke's residence, where the queen-dowager met with a surprise, as Ole refused to begin playing until she stopped talking. At Naples he experienced the misfortune of having his violin stolen, and he was obliged to buy a Nicholas Amati, for which he paid a very high price. After playing and making a great success in Rome, he returned to Paris, where he now found the doors of the Grand Opéra open to him, and he gave several concerts there.

In 1836 he married Félicie Villernot, the granddaughter of the lady in whose house he had met with so much kindness during his first stay in Paris.

Following the advice of Rossini, he went to London, where he made his usual success, notwithstanding the intrigues of certain musicians, who endeavoured to discredit him. Such was his popularity in England that he received for one concert, at Liverpool, the sum of £800, and in sixteen months' time he gave two hundred and seventy-four concerts in the United Kingdom.

He now decided to visit Germany, and on his way through Paris he made the acquaintance of Paganini, who greeted him with the utmost cordiality. He went through Germany giving many concerts, and visited Cassel, where he was now received by Spohr with every mark of distinction. He played in Berlin, where his success was great, notwithstanding some adverse criticism. He also played in Vienna and Buda-Pesth, and so on through Russia. At St. Petersburg he gave several concerts before audiences of five thousand people. He now went through Finland and so on to Sweden and Norway, where he was fêted.

Although closely followed by Vieuxtemps and Artot, Ole Bull was the first celebrated violinist to visit America, and in 1843 he made his first trip, landing in Boston in November of that year and proceeding directly to New York, playing for the first time on Evacuation Day. "John Bull went out on this day," he said, "and Ole Bull comes in." He remained two years in the United States, during which time he played in two hundred concerts and met with many remarkable adventures. During his sojourn he wrote a piece called "Niagara," which he played for the first time in New York, and which became very popular. He also wrote "The Solitude of the Prairies," which won more immediate success.

He travelled during these two years more than one hundred thousand miles, and played in every city of importance. He is estimated to have netted by his trip over $80,000, besides which he contributed more than $20,000, by concerts, to charitable institutions. No artist ever visited the United States and received so many honours.

In 1852 he returned to America, and this time he was destined to meet with tribulation. It was his desire to aid the poor of his country by founding a colony. He therefore bought a tract of land of 125,000 acres in Potter County, Pennsylvania, on the inauguration of which he stated his purpose: "We are to found a New Norway, consecrated to liberty, baptised with independence, and protected by the Union's mighty flag." Some three hundred houses were built, with a store and a church, and a castle on a mountain, which was designed for his permanent home. Hundreds flocked to the new colony, and the scheme took nearly the whole of his fortune.

Ole Bull now started on a concert tour together with little Adelina Patti, her sister Amalia Patti Strakosch, and Mr. Maurice Strakosch. Patti was then only eight years old, and was already exciting the wonder of all who heard her.

When crossing the Isthmus of Panama his violin was stolen by a native porter, and Ole Bull was obliged to remain behind to find his instrument, while the company went on to California. He was now taken down with yellow fever, and owing to a riot in the town he was entirely neglected, and was obliged to creep off his bed on to the floor in order to escape the bullets which were flying about. On his recovery he set out for San Francisco, but the season was too late for successful concerts. He was miserably weak, and when he played his skin would break and bleed as he pressed the strings.

He now heard that there was some trouble in regard to his title to the land in Pennsylvania, and, hastening to Philadelphia, he was legally notified that he was trespassing.
