I also conducted a series of concerts at Ravinia Park, organized by the Chicago and Milwaukee Electric Railway to serve a similar commercial purpose. Chicago had, of course, enjoyed for years the splendid winter concerts of the Chicago Orchestra, first under Theodore Thomas and then under his successor, Frederick Stock, but this was the first time that symphonic concerts were given during the summer amid such charming surroundings on the borders of Lake Michigan. These concerts proved exceedingly popular, the audiences consisting not only of the North Shore residents but of thousands who came out from Chicago on trains and trolleys. After several years of this work, however, the incessant daily concerts, coming after an arduous winter season, began to pall on my musical nerves. I ran a real danger, if I continued, of becoming nothing but a musical routinier, with an inevitable loss of the enthusiasm and freshness which is an absolute necessity for the interpreter. I therefore gave up all conducting during the summer months. I founded the Damrosch Opera Company in 1895, and the harassing question of how to maintain my orchestra seemed solved, for, during the first year, my opera season lasted thirteen weeks and during the following three years, from twenty to thirty weeks each. This not only enabled me to maintain a beautifully trained orchestra for the Wagner operas, but also gave to my symphony performances a greater finish. The orchestra was now under my exclusive control and could rehearse as often as the endowed orchestra of Major Higginson. But as it was the opera that enabled me to give my men such a long engagement, its needs had to control all other arrangements, and gradually the regular sequence of my winter concerts in New York began to suffer. I could not keep my opera company in New York except for a limited period each year, and therefore had to fill in much of my time in Philadelphia, Boston, and the larger cities of the South and Middle West. In 1899 I was therefore finally compelled to give up the regular subscription series of our New York concerts and the New York Symphony Orchestra became a part of my travelling operatic organization. I made this sacrifice with a heavy heart, but at that time it was the only solution. An orchestra devoted only to concerts could not be maintained without an endowment, and that I did not have at the time, while the length of my Wagner opera season enabled me not only to give my men a good engagement but to have the pick of the best musicians in New York. From then on until 1903 most of our playing of symphonic music was only on our spring concert tours and at irregular intervals in New York.
