However, when Sousa called to ask that Clarke rejoin him for a world tour, he was greatly tempted. He was ready to play solos again and leave booking problems behind him. He consoled his wife and three children by promising to take them with him on the 1905 European tour. “My life seemed to be one of change,” wrote Clarke. “But I surely gained experience in all kinds of music.” From 1904 till 1917 Herbert Clarke, the self-taught cornetist, was soloist and assistant conductor of Sousa’s great band. On the podium he had the same appearance and directing style as Sousa. Outstanding as an arranger of band music, Clarke was invaluable. The two men worked together through all these years in confidential relationship. Between tours Clarke spent more time on the farm which he had bought near Reading, Pennsylvania, getting acquainted with his family and teaching and practicing. He told of his small daughter forgetting him after a long tour and running to tell her mother that a strange man was at the door. At the age of forty-five Clarke began to think of retiring from concert work. He went to Elkhart, Indiana, to head the cornet and trumpet department of C. G. Conn’s large factory with the understanding that he be released for tours with Sousa. Clarke held this position until Mr. Conn sold his factory in 1915. As a young man Clarke had declared that he would leave the concert field at the age of fifty. He insisted that he wanted to “quit in good standing, stay in one place, sleep in the same bed every night and quit traveling all over the world.” In September, 1917, Clarke severed his connection with Sousa’s band and accepted an offer to conduct the band of the Anglo-American Leather Company in Huntsville, Canada. At the end of this five year contract, Clarke moved to Los Angeles, California, where he planned to spend the rest of his life. No sooner had he got well started in teaching cornet and in launching a correspondence course than he accepted the leadership of the Long Beach, California, Municipal Band, for a six-month period. Under Clarke’s baton this band of twenty-five musicians grew to fifty-two and the six months lengthened to twenty years. Then Clarke’s physician ordered him to retire from work. During his many years of public service, Herbert Clarke made an enviable record. The degree of Doctor of Music was conferred upon him by Phillips University in 1934. He was the author of four books on the cornet. He traveled all over the world with the greatest bands of his day, having made thirty-four tours of the United States and four of Europe. He played over 6,000 programmed concert solos.
