Denver, Col., July 12. – Billie Burke, the actress, has accepted an offer for $30,000 for an engagement of five weeks with a Pacific coast movie concern. At the time of the death of Mr. Charles Frohman, it was predicted that Miss Burke would be under the management of her husband, Mr. Florenz Ziegfeld, Jr. This was denied later with the news that she would continue under the Frohman estate and that Mrs. Cushing was writing a new play for her. Miss Burke, it is believed, will leave the Frohman interests.
